The irony gnawed at me: My entire vocation as an investigative reporter was predicated on being able to reveal truths, and yet I could not even rustle up the evidence to convince my own mother that our 45th president was not, in fact, the hero she believed him to be. Or, for that matter, that John F. Kennedy Jr. was dead. Or that Tom Hanks had not been executed for drinking the blood of children.

The theories spun from Q’s messages seemed much easier to disprove. Oprah Winfrey couldn’t have been detained during a wave of deep state arrests because we could still see her conducting live interviews on television. Trump’s 4th of July speech at Mount Rushmore came to an end without John F. Kennedy Jr. revealing he was alive and stepping in as the president’s new running mate. The widespread blackouts that her Patriot friend’s “source from the Pentagon” had warned about failed to materialize. And I could testify firsthand that the CIA had no control over my newsroom’s editorial decisions.

“I believe the Holy Spirit led me to the QAnons to discover the truth which is being suppressed,” she texted me. “Otherwise, how would I be able to know the truth if the lamestream media suppresses the truth?”

Through the years, I’d battled against conspiracy theories my mom threw at me that were far more formidable than QAnon. I’d been stumped when she asked me to prove that Beyoncé wasn’t an Illuminati member, dumbfounded when research studies I sent her weren’t enough to reach an agreement on vaccine efficacy, and too worn down to say anything more than “that’s not true” when confronted with false allegations of murders committed by prominent politicians.

Eventually, I accepted the impasse. It didn’t seem healthy that every conversation we had would devolve into a circuitous debate about which one of us was on the side of the bad guys. So I tried to pick my battles.

But what I had dismissed as damaging inconsistencies turned out to be the core strength of the belief system: It was alive, flexible, sprouting more questions than answers, more clues to study, an investigation playing out in real time, with the fate of the world at stake.

With no overlap between our filters of reality, I was at a loss for any facts that would actually stick.

Meanwhile, she wondered where she’d gone wrong with me

She regretted not taking politics more seriously when I was younger. I’d grown up blinkered by American privilege, trained to ignore the dirty machinations securing my comforts. My mom had shed that luxury long ago.

The year my mom began falling down QAnon rabbit holes, I turned the age she was when she first arrived in the States. By then, I was no longer sure that America was worth the cost of her migration. When the real estate market collapsed under the weight of Wall Street speculation, she had to sell our house at a steep loss to avoid foreclosure and her budding career as a realtor evaporated. Her near–minimum wage jobs weren’t enough to cover her bills, so her credit card debts rose. She delayed retirement plans because she saw no path to breaking even anytime soon, though she was hopeful that a turnaround was on the horizon. Through the setbacks and detours, she drifted into the arms of the people and beliefs I held most responsible for her troubles.

With a fervor I knew was futile, I’d tell my mom she was missing the real conspiracy: The powerful people shaping policy to benefit their own interests, to maintain wealth and white predominance, through tax cuts and voter suppression, were commandeering her support solely by catering to her stance on the one issue she cared most about.

The voice my mom trusted most now was Trump’s. Our disagreements were no longer ideological to her but part of a celestial conflict.

“I love you but you have to be on the side of good,” she texted me. “Im sad cuz u have become part of the deep state. May God have mercy on you...I pray you will see the truth of the evil agenda and be on the side of Trump.”

She likened her fellow Patriots to the early Christians who spread the word of Jesus at the risk of persecution. She often sent me a meme with a caption about “ordinary people who spent countless hours researching, debating, meditating and praying” for the truth to be revealed to them. “Although they were mocked, dismissed and cast off, they knew their souls had agreed long ago to do this work.”

Last summer, as my mom marched in a pink MAGA hat amid maskless crowds, and armed extremists stalked racial justice protests, and a disputed election loomed like a time bomb, I entertained my darkest thoughts about the fate of our country. Was there any hope in a democracy without a shared set of basic facts? Had my elders fled one authoritarian regime only for their children to face another? Amid the gloom, I found only a single morsel of solace: My mom was as hopeful as she’d ever been.

I wish I could offer some evidence showing that the gulf between us might be narrowing, that my love, persistence, and collection of facts might be enough to draw her back into a reality we share, and that when our wager about the storm comes due in a few months, she’ll realize that the voices she trusts have been lying to her. But I don’t think that will happen

What can I do but try to limit the damage? Send my mom movie recommendations to occupy the free time she instead spends on conspiracy research. Shift our conversations to the common ground of cooking recipes and family gossip. Raise objections when her beliefs nudge her toward dangerous decisions.

I now understand our debates as marks of the very bond I thought was disintegrating. No matter how far she believes I’ve fallen into the deep state, how hard I fight for the forces of evil, how imminent the grand plan’s rapture, my mom will be there on the other side of the line putting in a good word for me with the angels and saints, trying to save me from damnation. And those are the two realities we live in. ●

The quality of mathematics research in the United States today is the envy of the scientific world. This is a direct result of the openness and inclusivity of the profession.

Can Americans maintain this unmatched excellence in the future? There are worrisome signs that suggest not.

The Organization for Economic Cooperation and Development compares mathematical proficiency among 15-year-olds by country worldwide. According to its 2018 report, America ranked 37th while China, America’s main competitor for world leadership, came in first.

This is despite the fact that the United States is the fifth-highest spender per pupil among the 37 developed OECD nations

This massive failure of our K-12 education system trickles through the STEM pipeline.

At the undergraduate level, too few American students are prepared for higher-level mathematics courses. These students are then unprepared for rigorous graduate-level work

According to our own experiences at the universities where we teach, an overwhelming majority of American students with strong math backgrounds are either foreign-born or first-generation students who have additional support from their education-conscious families. At all levels, STEM disciplines are more and more dependent on a constant flow of foreign talent.

There are many reasons for this failure, but the way that we educate and prepare teachers is particularly influential. The vast majority of K-12 math teachers are graduates of teacher-preparation programs that teach very little substantive mathematics

This has led to a constant stream of ill-advised and dumbed-down reforms. One of the latest fads is anti-racist mathematics. Promoted in several states, the bizarre doctrine threatens to further degrade the teaching of mathematics.

Another major concern is the twisted interpretation of diversity, equity, and inclusion (DEI).

Under the banner of DEI, universities are abandoning the use of standardized tests like the SAT and GRE in admissions, and cities are considering scrapping academic tracking and various gifted programs in schools, which they deem “inequitable.”

such programs are particularly effective, when properly implemented, at discovering and encouraging talented children from disadvantaged backgrounds.

The new 2021 Mathematics Framework, currently under consideration by California’s Department of Education, does away “with all tracking, acceleration, gifted programs, or any instruction that involves clustering by individual differences, without expressing any awareness of the impact these drastic alterations would have in preparing STEM-ready candidates.”

These measures will not only hinder the progress of the generations of our future STEM workforce but also contribute to structural inequalities, as they are uniquely detrimental to students whose parents cannot send them to private schools or effective enrichment programs.

These are just a few examples of an unprecedented fervor for revolutionary change in the name of Critical Race Theory (CRT), a doctrine that views the world as a fierce battleground for the narratives of various identity groups.

This will only lead to a further widening of racial disparities in educational outcomes while lowering American children’s rankings in education internationally.

Ill-conceived DEI policies, often informed by CRT, and the declining standards of K-12 math education feed each other in a vicious circle

Regarding minorities, in particular, public K-12 education all too often produces students unprepared to compete, thus leading to large disparities in admissions at universities, graduate programs, and faculty positions. This disparity is then condemned as a manifestation of structural racism, resulting in administrative measures to lower the evaluation criteria. Lowering standards at all levels leads eventually to even worse outcomes and larger disparities, and so on in a downward spiral.

A case in point is the recent report by the American Mathematical Society that accuses the entire mathematics community, with the thinnest of specific evidence, of systemic racial discrimination. A major justification put forward for such a grave accusation is the lack of sufficient representation of Black mathematicians in the professio

the report, while raising awareness of several ugly facts from the long-ago past, makes little effort to address the real reasons for this, mainly the catastrophic failure of the K-12 mathematical educational system.

The National Science Foundation, a federal institution meant to support fundamental research, is now diverting some of its limited funding to various DEI initiatives of questionable benefit.

Meanwhile, other countries, especially China, are doing precisely the opposite, following the model of our past dedication to objective measures of excellence. How long before we will see a reverse exodus, away from the United States?

The present crisis can still be reversed by focusing on a few concrete actions:

Improve schools in urban areas and inner-city neighborhoods by following the most promising education programs. These programs demonstrate that inner-city children benefit if they are challenged by high standards and a nurturing environment.

Follow the lead of other highly successful rigorous programs such as BASIS schools and Math for America, which focus on rigorous STEM curricula, combined with 21st-century teaching methods, and recruit talented teachers to help them build on their STEM knowledge and teaching methods.

Increase, rather than eliminate, tailored instruction, both for accelerated and remedial math courses.

Reject the soft bigotry of low expectations, that Black children cannot do well in competitive mathematics programs and need dumbed-down ethnocentric versions of mathematics.

Uphold the objective selection process based on merit at all levels of education and research.

Historians are no longer grandees at the centre of a fixed civilisation; they are simply journalists writing about celebrities who haven't got the grace to be alive any more

There are those who wonder if the whole of history is now valuable only as a politically correct lesson in the stupidity and cruelty of monarchs, aristocrats, industrialists and generals

You don't even have to dignify it with ideological abstractions any more; history is really the story of a series of subjugations, oppressions, exploitations and abuses.

The biggest challenge facing the great teachers and communicators of history is not to teach history itself, nor even the lessons of history, but why history matters.

A history in which historians have to stand on one side of an argument or another, for, in between, they are nothing but dry-as-dust statisticians

we measure the exponential growth in the public appetite for history

History, then, as one long, grovelling apology or act of self-abasement and self-laceration.

After all, isn't that what poetry and novels show, that humanity is best comprehended by understanding humans rather than ideas? But for some, this leads to the worry that history can now only mean witness

Certainly, history is popular in grand traditional forms, but new subgenres of history have, for the last 20 years, exploded in popularity, too.

We haven't arrived at our own moral and ethical imperatives by each of us working them out from first principles; we have inherited them and they were born out of blood and suffering, as all human things and human beings are.

This does not stop us from admiring and praising the progressive heroes who got there early and risked their lives to advance causes that we now take for granted.

In the end, I suppose history is all about imagination rather than facts

If you cannot feel what our ancestors felt when they cried: 'Wilkes and Liberty!' or, indeed, cried: 'Death to Wilkes!', if you cannot feel with them, then all you can do is judge them and condemn them, or praise them and over-adulate them.

History is not the story of strangers, aliens from another realm; it is the story of us had we been born a little earlier

History is memory

forgetting seems to be an active mechanism that is constantly at work in the brain.

“To have proper memory function, you have to have forgetting.

Different types of memory are created and stored in varying ways, and in various areas of the brain.

Neurons communicate with each other through synapses — junctions between these cells that include a tiny gap across which chemical messengers can be sent

The more often a memory is recalled, the stronger its neural network becomes. Over time, and through consistent recall, the memory becomes encoded in both the hippocampus and the cortex

Because the hippocampus is not where long-term memories are stored in the brain, its dynamic nature is not a flaw but a feature

Neuroscientists often refer to this physical representation of a memory as an engram. They think that each engram has a number of synaptic connections, sometimes even in several areas of the brain, and that each neuron and synapse can be involved in multiple engrams

The brain is always trying to forget the information it’s already learnt,

Hardt’s lab showed that a dedicated mechanism continuously promotes the expression of AMPA receptors at synapses.

To forget certain things, it seemed that the rat brain had to proactively destroy connections at the synapse. Forgetting, Hardt says, “is not a failure of memory, but a function of it”.

Paul Frankland, a neuroscientist at the Hospital for Sick Children in Toronto, Canada, had also found evidence that the brain is wired to forget

Frankland was studying the production of new neurons, or neurogenesis, in adult mice. The process had long been known to occur in the brains of young animals, but had been discovered in the hippocampi of mature animals only about 20 years earlier. Because the hippocampus is involved in memory formation, Frankland and his team wondered whether increasing neurogenesis in adult mice could help the rodents to remember.

Eventually, it exists independently in the cortex, where it is put away for long-term storage.

Researchers think that the human brain might operate in a similar way

Studies of people with exceptional autobiographical memories or with impaired ones seem to bear this out

People with a condition known as highly superior autobiographical memory (HSAM) remember their lives in such incredible detail that they can describe the outfit that they were wearing on any particular day

Those with severely deficient autobiographical memory (SDAM), however, are unable to vividly recall specific events in their lives

As a result, they also have trouble imagining what might happen in the future

By better understanding how we forget, through the lenses of both biology and cognitive psychology, Anderson and other researchers might be edging nearer to improving treatments for anxiety, PTSD and even Alzheimer’s disease

Hardt thinks that Alzheimer’s disease might also be better understood as a malfunction of forgetting rather than remembering

But more memory researchers are shifting their focus to examine how the brain forgets, as well as how it remembers

In the past decade, researchers have begun to view forgetting as an important part of a whole

Why do we have memory at all? As humans, we entertain this fantasy that it’s important to have autobiographical details,

Forgetting enables us as individuals, and as a species, to move forwards.

Scientists have spent hundreds of years trying to understand how human sensory organs work, concluding that sight is the most important sense, followed hearing, touch, taste and smell.

To answer this question, an international team led by Professor Majid, conducted a large-scale experiment to investigate the ease with which people could communicate about colors, shapes, sounds, textures, tastes and smells

Speakers of 20 diverse languages, including three different sign languages, from across the globe were tested, ranging from hunter-gatherers to post-industrial societies

If the commonly accepted hierarchy of the senses were true, participants in the study should have been able to communicate about vision most easily, followed by sounds, such as loud and quiet; textures, such as smooth and rough; taste, such as sweet and sour; and smell, such as chocolate and coffee

"While English speakers behaved as predicted, describing sight and sound with ease, this was not the case across all cultures

What this study shows us is that we can't always assume that understanding certain human functions within the context of the English language provides us with a universally relevant perspective or solution

In a modern digital-led world, which typically engages sight and hearing, it could be worthwhile learning from other cultures in the way that taste and smell can be communicated

This could be particularly important for the future of some professions, such as the food industry, for example, where being able to communicate about taste and smell is essential

Worldwide, some mutually understandable ways of speaking, which one might think of as “dialects” of one language, are actually treated as separate languages

It turns out that it’s also impossible to determine precisely where one “language” leaves off and another begins

As such, English tempts one with a tidy dialect-language distinction based on “intelligibility”: If you can understand it without training, it’s a dialect of your own language; if you can’t, it’s a different language

The only thing that can save an attempt to impose a formal definition on the terms “language” and “dialect” now is perhaps to be found in popular usage, which suggests that languages are written and standardized and have a literature, while dialects are oral, without codified rules, and have no literature.

Namely, it’s the implication that there is something lesser about a “dialect.

As often as not, obscure, unwritten “dialects” are much more grammatically complicated than familiar “languages.”

A language, then, is indeed a dialect with an army and a navy; or, more to the point, a language is a dialect that got put up in the shop window.

In popular usage, a language is written in addition to being spoken, while a dialect is just spoken. But in the scientific sense, the world is buzzing with a cacophony of qualitatively equal “dialects,” often shading into one another like colors (and often mixing, too), all demonstrating how magnificently complicated human speech can be.

I learned something more useful: the existence of non-fiction literature that can teach you anything.

something felt odd. Whenever a conversation revolved around a serious non-fiction book I read, such as ‘Sapiens’ or ‘Thinking Fast and Slow,’ I could never remember much. Turns out, I hadn’t absorbed as much information as I’d believed. Since I couldn’t remember much, I felt as though reading wasn’t an investment in knowledge but mere entertainment.

When I opened up about my struggles, many others confessed they also can’t remember most of what they read, as if forgetting is a character flaw. But it isn’t.

It’s the way we work with books that’s flawed.

there’s a better way to read. Most people rely on techniques like highlighting, rereading, or, worst of all, completely passive reading, which are highly ineffective.

Since I started applying evidence-based learning strategies to reading non-fiction books, many things have changed. I can explain complex ideas during dinner conversations. I can recall interesting concepts and link them in my writing or podcasts. As a result, people come to me for all kinds of advice.

What’s the Architecture of Human Learning and Memory?

Human brains don’t work like recording devices. We don’t absorb information and knowledge by reading sentences.

we store new information in terms of its meaning to our existing memory

we give new information meaning by actively participating in the learning process — we interpret, connect, interrelate, or elaborate

To remember new information, we not only need to know it but also to know how it relates to what we already know.

Learning is dependent on memory processes because previously-stored knowledge functions as a framework in which newly learned information can be linked.”

Human memory works in three stages: acquisition, retention, and retrieval. In the acquisition phase, we link new information to existing knowledge; in the retention phase, we store it, and in the retrieval phase, we get information out of our memory.

Retrieval, the third stage, is cue dependent. This means the more mental links you’re generating during stage one, the acquisition phase, the easier you can access and use your knowledge.

we need to understand that the three phases interrelate

creating durable and flexible access to to-be-learned information is partly a matter of achieving a meaningful encoding of that information and partly a matter of exercising the retrieval process.”

Next, we’ll look at the learning strategies that work best for our brains (elaboration, retrieval, spaced repetition, interleaving, self-testing) and see how we can apply those insights to reading non-fiction books.

The strategies that follow are rooted in research from professors of Psychological & Brain Science around Henry Roediger and Mark McDaniel. Both scientists spent ten years bridging the gap between cognitive psychology and education fields. Harvard University Press published their findings in the book ‘Make It Stick.

#1 Elaboration

“Elaboration is the process of giving new material meaning by expressing it in your own words and connecting it with what you already know.”

Why elaboration works: Elaborative rehearsal encodes information into your long-term memory more effectively. The more details and the stronger you connect new knowledge to what you already know, the better because you’ll be generating more cues. And the more cues they have, the easier you can retrieve your knowledge.

How I apply elaboration: Whenever I read an interesting section, I pause and ask myself about the real-life connection and potential application. The process is invisible, and my inner monologues sound like: “This idea reminds me of…, This insight conflicts with…, I don’t really understand how…, ” etc.

For example, when I learned about A/B testing in ‘The Lean Startup,’ I thought about applying this method to my startup. I added a note on the site stating we should try it in user testing next Wednesday. Thereby the book had an immediate application benefit to my life, and I will always remember how the methodology works.

How you can apply elaboration: Elaborate while you read by asking yourself meta-learning questions like “How does this relate to my life? In which situation will I make use of this knowledge? How does it relate to other insights I have on the topic?”

While pausing and asking yourself these questions, you’re generating important memory cues. If you take some notes, don’t transcribe the author’s words but try to summarize, synthesize, and analyze.

#2 Retrieval

With retrieval, you try to recall something you’ve learned in the past from your memory. While retrieval practice can take many forms — take a test, write an essay, do a multiple-choice test, practice with flashcards

the authors of ‘Make It Stick’ state: “While any kind of retrieval practice generally benefits learning, the implication seems to be that where more cognitive effort is required for retrieval, greater retention results.”

Whatever you settle for, be careful not to copy/paste the words from the author. If you don’t do the brain work yourself, you’ll skip the learning benefits of retrieval

Retrieval strengthens your memory and interrupts forgetting and, as other researchers replicate, as a learning event, the act of retrieving information is considerably more potent than is an additional study opportunity, particularly in terms of facilitating long-term recall.

How I apply retrieval: I retrieve a book’s content from my memory by writing a book summary for every book I want to remember. I ask myself questions like: “How would you summarize the book in three sentences? Which concepts do you want to keep in mind or apply? How does the book relate to what you already know?”

I then publish my summaries on Goodreads or write an article about my favorite insights

How you can apply retrieval: You can come up with your own questions or use mine. If you don’t want to publish your summaries in public, you can write a summary into your journal, start a book club, create a private blog, or initiate a WhatsApp group for sharing book summaries.

a few days after we learn something, forgetting sets in

#3 Spaced Repetition

With spaced repetition, you repeat the same piece of information across increasing intervals.

The harder it feels to recall the information, the stronger the learning effect. “Spaced practice, which allows some forgetting to occur between sessions, strengthens both the learning and the cues and routes for fast retrieval,”

Why it works: It might sound counterintuitive, but forgetting is essential for learning. Spacing out practice might feel less productive than rereading a text because you’ll realize what you forgot. Your brain has to work harder to retrieve your knowledge, which is a good indicator of effective learning.

How I apply spaced repetition: After some weeks, I revisit a book and look at the summary questions (see #2). I try to come up with my answer before I look up my actual summary. I can often only remember a fraction of what I wrote and have to look at the rest.

“Knowledge trapped in books neatly stacked is meaningless and powerless until applied for the betterment of life.”

How you can apply spaced repetition: You can revisit your book summary medium of choice and test yourself on what you remember. What were your action points from the book? Have you applied them? If not, what hindered you?

By testing yourself in varying intervals on your book summaries, you’ll strengthen both learning and cues for fast retrieval.

Why interleaving works: Alternate working on different problems feels more difficult as it, again, facilitates forgetting.

How I apply interleaving: I read different books at the same time.

1) Highlight everything you want to remember

#5 Self-Testing

While reading often falsely tricks us into perceived mastery, testing shows us whether we truly mastered the subject at hand. Self-testing helps you identify knowledge gaps and brings weak areas to the light

“It’s better to solve a problem than to memorize a solution.”

Why it works: Self-testing helps you overcome the illusion of knowledge. “One of the best habits a learner can instill in herself is regular self-quizzing to recalibrate her understanding of what she does and does not know.”

How I apply self-testing: I explain the key lessons from non-fiction books I want to remember to others. Thereby, I test whether I really got the concept. Often, I didn’t

instead of feeling frustrated, cognitive science made me realize that identifying knowledge gaps are a desirable and necessary effect for long-term remembering.

How you can apply self-testing: Teaching your lessons learned from a non-fiction book is a great way to test yourself. Before you explain a topic to somebody, you have to combine several mental tasks: filter relevant information, organize this information, and articulate it using your own vocabulary.

Now that I discovered how to use my Kindle as a learning device, I wouldn’t trade it for a paper book anymore. Here are the four steps it takes to enrich your e-reading experience

How you can apply interleaving: Your brain can handle reading different books simultaneously, and it’s effective to do so. You can start a new book before you finish the one you’re reading. Starting again into a topic you partly forgot feels difficult first, but as you know by now, that’s the effect you want to achieve.

it won’t surprise you that researchers proved highlighting to be ineffective. It’s passive and doesn’t create memory cues.

2) Cut down your highlights in your browser

After you finished reading the book, you want to reduce your highlights to the essential part. Visit your Kindle Notes page to find a list of all your highlights. Using your desktop browser is faster and more convenient than editing your highlights on your e-reading device.

Now, browse through your highlights, delete what you no longer need, and add notes to the ones you really like. By adding notes to the highlights, you’ll connect the new information to your existing knowledge

3) Use software to practice spaced repetitionThis part is the main reason for e-books beating printed books. While you can do all of the above with a little extra time on your physical books, there’s no way to systemize your repetition praxis.

Readwise is the best software to combine spaced repetition with your e-books. It’s an online service that connects to your Kindle account and imports all your Kindle highlights. Then, it creates flashcards of your highlights and allows you to export your highlights to your favorite note-taking app.

Common Learning Myths DebunkedWhile reading and studying evidence-based learning techniques I also came across some things I wrongly believed to be true.

#2 Effective learning should feel easyWe think learning works best when it feels productive. That’s why we continue to use ineffective techniques like rereading or highlighting. But learning works best when it feels hard, or as the authors of ‘Make It Stick’ write: “Learning that’s easy is like writing in sand, here today and gone tomorrow.”

In Conclusion

I developed and adjusted these strategies over two years, and they’re still a work in progress.

Try all of them but don’t force yourself through anything that doesn’t feel right for you. I encourage you to do your own research, add further techniques, and skip what doesn’t serve you

“In the case of good books, the point is not to see how many of them you can get through, but rather how many can get through to you.”— Mortimer J. Adler

Some of the most common types of illusory percepts are those that affect the impression of size, length or distance.

As visual processing needs to be both rapid and generally accurate, the brain constantly uses shortcuts and makes assumptions about the world that can, in some cases, be misleading.

These illusions are the result of visual processes shaped by evolution. Using that process may have been once beneficial (or still is), but it also allows our brains to be tricked.

if animals are tricked by the same illusions, then perhaps revealing why a different evolutionary path leads to the same visual process might help us understand why evolution favours this development.

Great bowerbirds could be the ultimate illusory artists. For example, their males construct forced perspective illusions to make them more attractive to mates.

When a male has two smaller clawed males on either side of him he is more attractive to a female (because he looks relatively larger) than if he was surrounded by two larger clawed males.

This effect is known as the Ebbinghaus illusion (see image), and suggests that males may easily manipulate their perceived attractiveness by surrounding themselves with less attractive rivals.

Deceptions of the senses are the truths of perception.

Visual illusions (and those in the non-visual senses) are a crucial tool for determining what perceptual assumptions animals make about the world around them.

Two of the most important factors, Peterson explained, are whether the memory “has emotion infused in it,” and whether the memory is coherent: Does the story our memory tells us actually hang together and make sense when we recall it later?

A professor at the University of North Carolina-Chapel Hill, Reznick explained that shortly after birth, infants can start forming impressions of faces and react when they see those faces again; this is recognition memory. The ability to understand words and learn language relies on working memory, which kicks in at around six months old. More sophisticated forms of memory develop in the child’s second year, as semantic memory allows children to retain understanding of concepts and general knowledge about the world.

I formed earlier memories using more rudimentary, pre-verbal means, and that made those memories unreachable as the acquisition of language reshaped how my mind works, as it does for everyone.

False memories do exist, but their construction appears to begin much later in life

A study by Peterson presented young children with fictitious events to see if they could be misled into remembering these non-existent events, yet the children almost universally avoided the bait. As for why older children and adults begin to fill in gaps in their memories with invented details, she pointed out that memory is a fundamentally constructive activity: We use it to build understanding of the world, and that sometimes requires more complete narratives than our memories can recall by themselves.

as people get older, it becomes easier to conflate actual memories with other stimuli.

He explained that recognition memory is our most pervasive system, and that associations with my hometown I formed as an infant could well have endured more than 20 years later, however vaguely.

give me enough time, and I’m sure that detail will be added to my memory. It’s just too perfect a story.

or so long the powerful have had room to speak, to say anything they wanted, and back it up with economic and violent force. For people used to power, speaking on the net gives them a granularity in their speech without precedent. It empowers them to speak in ever more sophisticated and persuasive ways.

I found myself on Twitter one night speaking to men’s rights advocates about sexual consent. I tried my gentleness, I tried to explain my concerns, my doubts, the outcomes I feared when people weren’t able to give sober and informed consent. I never got angry, but also tried to understand their fears. Eventually it resolved into a productive conversation. They were always hesitant, but they couldn’t seem to stay mad at me. I came to understand more about how men come to that position, and how to meet them where they are. Undoubtedly it won’t always work, but for those who only want to scream and never to talk, I can at least now see the depth of their fear and feel compassion for them.

One day I spoke with a man who hated the idea that he might have white privilege. I tried to explain gently what it meant, but he could only see his own suffering and misfortune, and those without his privilege doing better than him. I talked to him more about his story, looking for a place to explain in terms he would understand what this thing was, and why it was there even if he didn’t see it as benefitting him. Eventually he pulled his trump card: his life was so bad he was suicidal. The only reason he hadn’t killed himself, he told me, was that he didn’t have the courage. I realized this wasn’t a political conversation at all, this was a soul in pain, crying for help.

Beyond the text and pictures we see before us is the skin, and beneath, the blood and viscera, all the way to the cavern of the brain, the mind made of time and memories. We are, every one of us, creatures of need and connection, not merely eschewing disconnection but beings literally incapable of unconnected life.

I was hesitant with the Times. They were far out of my comfort zone, but I felt that the people I was talking to had a sincerity greater than their confusion. Nothing that has happened since then has dissuaded me from that impression.

If you’re reading this, especially on the internet, you are the teacher for those institutions at a local, national, and global level. I understand that you didn’t ask for this position. Neither did I. History doesn’t ask you if you want to be born in a time of upheaval, it just tells you when you are. When the backlash began, I got the call from the person who had sought me out and recruited me. The fear I heard in that shaky voice coming through my mobile phone was unmistakable. It was the fear of a mob, of the unknown, and of the idea that maybe they had gotten it wrong and done something terrible. I have felt all of those things. Many of us have. It’s not a place of strength, even when it seems to be coming from someone standing in a place of power. The Times didn’t know what the internet was doing—tearing down a new hire, exposing a fraud, threatening them—everything seemed to be in the mix.

I had even written about context collapse myself, but that hadn’t saved me from falling into it, and then hurting other people I didn’t mean to hurt. This particular collapse didn’t create much of a doppelgänger, but it did find me spending a morning as a defensive jerk. I’m very sorry for that dumb mistake. It helped me learn a lesson: Be damn sure when you make angry statements. Check them out long enough that, even if the statements themselves are still angry, you are not angry by the time you make them. Again and again, I have learned this: Don’t internet angry. If you’re angry, internet later.

I think if I’d gotten to write for the Times as part of their editorial board, this might have been different. I might have been in a position to show how our media doppelgängers get invented, and how we can unwind them. It takes time and patience. It doesn’t come from denying the doppelgänger—there’s nothing there to deny. I was accused of homophobia because of the in-group language I used with anons when I worked with them. (“Anons” refers to people who identify as part of the activist collective Anonymous.) I was accused of racism for use of taboo language, mainly in a nine-year-old retweet in support of Obama. Intentions aside, it wasn’t a great tweet, and I was probably overemotional when I retweeted it.

In late 2015 I woke up a little before 6 a.m., jet-lagged in New York, and started looking at Twitter. There was a hashtag, I don’t remember if it was trending or just in my timeline, called #whitegirlsaremagic. I clicked on it, and found it was racist and sexist dross. It was being promulgated in opposition to another hashtag, #blackgirlsaremagic. I clicked on that, and found a few model shots and borderline soft-core porn of black women. Armed with this impression, I set off to tweet in righteous anger about how much I disliked women being reduced to sex objects regardless of race. I was not just wrong in this moment, I was incoherently wrong. I had made my little mental model of what #blackgirlsaremagic was, and I had no clue that I had no clue what I was talking about. My 60-second impression of #whitegirlsaremagic was dead-on, but #blackgirlsaremagic didn’t fit in the last few tweets my browser had loaded.

I had been a victim of something the sociologists Alice Marwick and danah boyd call context collapse, where people create online culture meant for one in-group, but exposed to any number of out-groups without its original context by social-media platforms, where it can be recontextualized easily and accidentally.

Not everyone believes loving engagement is the best way to fight evil beliefs, but it has a good track record. Not everyone is in a position to engage safely with racists, sexists, anti-Semites, and homophobes, but for those who are, it’s a powerful tool. Engagement is not the one true answer to the societal problems destabilizing America today, but there is no one true answer. The way forward is as multifarious and diverse as America is, and a method of nonviolent confrontation and accountability, arising from my pacifism, is what I can bring to helping my society.

Here is your task, person on the internet, reader of journalism, speaker to the world on social media: You make the world now, in a way that you never did before. Your beliefs have a power they’ve never had in human history. You must learn to investigate with a scientific and loving mind not only what is true, but what is effective in the world. Right now we are a world of geniuses who constantly love to call each other idiots. But humanity is the most complicated thing we’ve found in the universe, and so far as we know, we’re the only thing even looking. We are miracles by the billions with powers and luxuries beyond the dreams of kings of old.

We are powerful creatures, but power must come with gentleness and responsibility. No one prepared us for this, no one trained us, no one came before us with an understanding of our world. There were hints, and wise people, and I lean on and cherish them. But their philosophies and imaginations can only take us so far. We have to build our own philosophies and imagine great futures for our world in order to have any futures at all. Let mercy guide us forward in these troubled times. Let yourself imagine, because imagination is the wellspring of hope. Here, in the beginning of the 21st century, hope is our duty to the future.

The only problem is that perfect rulebooks don’t exist, because natural language is far too complex and haphazard to be reduced to a rigid set of specifications.

Researchers simply fed their neural networks massive amounts of written text copied from freely available sources like Wikipedia — billions of words, preformatted into grammatically correct sentences — and let the networks derive next-word predictions on their own. In essence, it was like asking the person inside a Chinese room to write all his own rules, using only the incoming Chinese messages for reference.“The great thing about this approach is it turns out that the model learns a ton of stuff about syntax,”

The nonsequential nature of the transformer represented sentences in a more expressive form, which Uszkoreit calls treelike. Each layer of the neural network makes multiple, parallel connections between certain words while ignoring others — akin to a student diagramming a sentence in elementary school. These connections are often drawn between words that may not actually sit next to each other in the sentence. “Those structures effectively look like a number of trees that are overlaid,” Uszkoreit explained.

But instead of concluding that BERT could apparently imbue neural networks with near-Aristotelian reasoning skills, they suspected a simpler explanation: that BERT was picking up on superficial patterns in the way the warrants were phrased.

When Baidu researchers began developing their own language model, they wanted to build on the masking technique. But they realized they needed to tweak it to accommodate the Chinese language.In English, the word serves as the semantic unit—meaning a word pulled completely out of context still contains meaning. The same cannot be said for characters in Chinese.

It considers the ordering of sentences and the distances between them, for example, to understand the logical progression of a paragraph. Most important, however, it uses a method called continuous training that allows it to train on new data and new tasks without it forgetting those it learned before. This allows it to get better and better at performing a broad range of tasks over time with minimal human interference.

“When we first started this work, we were thinking specifically about certain characteristics of the Chinese language,” says Hao Tian, the chief architect of Baidu Research. “But we quickly discovered that it was applicable beyond that.”

This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting

Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators and food sources. And if an insect can display such as thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.

"This is a huge endeavor for the human species, and it'll take cooperation from more than just our own space program," Stack said. "Once the resources are there, we can develop the technology. It's getting the buy-in from international partners and from our own space administration and government to really make this happen."

No matter the mission, sticking the landing is key for future success. The 2020 rover will land on Mars using the new Terrain Relative Navigation system, which allows the lander to avoid any large hazards in the landing zone.

Astronauts exploring Mars will need oxygen, but carting enough to sustain them on a spacecraft isn't viable. The Mars 2020 rover will carry MOXIE on board, or the Mars Oxygen In-Situ Resource Utilization Experiment.

Speaking of "The Martian," the events of the book and its film adaptation are set in motion when a surprise, devastating dust storm impacts astronauts on the Red Planet. Understanding the weather and environment on Mars will be crucial for determining the conditions astronauts will face.

For the first time, a surface mission will include a ground-penetrating radar instrument called RIMFAX, or Radar Imager for Mars' Subsurface Experiment. It will be able to peek beneath the surface and study Martian geology, looking for rock, ice and boulder layers. Scientists hope that RIMFAX will help them understand the geologic history of Jezero Crater, according to David Paige, principal investigator for the experiment at the University of California, Los Angeles.

Instead of referring to global warmer, the concept is dubbed "climate change" which lessens fears associated with global warming.

To better understand the way we react to information, research on communication is vital to understanding our reactions, emotions and how they build our behaviors and actions.

Children learn different communication, language and literacy skills through a structure of literacy framework that are related to development.

The process tries to make children to enjoy communication, language and literacy and be enthusiastic about the learning it .

They develop understanding of the correspondence between spoken and written sounds and learn to link sounds and letters and use their knowledge to read and write simple words by sounding out and blending.

The development of a national infrastructure is capable of providing ongoing professional development, quality assurance and data collection for the intervention.

The observations should be shared with the group to help make improvements in future performances.

Observing and encouraging babies and children's use of mirrors for self exploration of facial expression and gesture.

At times it can be useful to encourage children to use their home language, for example when organising initial ideas.

New buildings should be physically accessible to disabled pupils and will involve improving access to existing buildings including ramps, wider doors, low sinks, etc

All opportunities need to be well grounded in positive pride for the styles common in every child's own background. 

No test is perfectly accurate; all generate false positives and false negatives. How many varies by the test — the new Abbott Labs test, for example, has a false negative rate of about 3 percent and a false positive rate of about 1.5 percent.

We’d also require public understanding that test results are a risk-assessment tool rather than a definitive answer. And shifting the public’s thinking might be harder than shifting Trump.

Doing that would also require fundamentally changing our thinking.

For mass testing to work, people will need to understand that even an event where all attendees just tested negative isn’t necessarily covid-free, because some false negatives might have slipped through

Giving hundreds of millions of citizens this crash course in elementary statistics would be very difficult. Teaching people how to think about a positive result would be even harder — especially if mass testing does its job of reducing caseloads. Because as case numbers fall, false positives will become a bigger and bigger problem.

Say we’re testing 200 people, 10 of whom have covid-19. Given its rate of false negatives, the Abbott test would probably catch all 10. But with false positives, it could also tell one or two people who don’t have covid-19 that they’re infected. That’s not ideal — as good citizens, they’d have to go home and quarantine. But a more sensitive follow-up test could substantially mitigate this problem, shortening such quarantines to a day or so. It would be worth it to get those 10 true positives out of circulation.

Doing this, we might eventually reduce the share of the population that’s infected to, say, 0.5 percent from 5 percent. Unfortunately, the false positive rate won’t budge, so now for every one true positive uncovered, roughly three false positives would still be generated.

That’s inherently costly: Every false positive means skipping your flight, rehearsal or birthday party. But it would be catastrophic if people didn’t understand that a positive covid-19 test is a guideline, not a guarantee

People who think that they’ve had covid-19, when they haven’t, are apt to go out and engage in risky behavior, maybe a lot of it. And if mass testing ever becomes common, there could be a lot of those people.

So mass testing isn’t just a matter of getting a test that is cheap enough and plentiful enough; the administration and the public must be educated to use this bounty wisely. That’s a hard messaging problem. Given the alternative, though, it’s the kind of problem we’d really like to have.

Einstein, Mozart, Michelangelo, Steve Jobs, Bill Gates – all these overachievers are widely believed to be, or have been, on the spectrum.

I used recreational drugs to smooth me through the challenges of social communication.

With every interaction, verbal or written, I go through a mental checklist: is my response appropriate? Is it relevant? Is this something only I am going to find interesting? Is my tone right? Trying to follow social rules and adapt to an allistic [non-autistic] world is exhausting. No one sees what is going on inside my head.

Misunderstandings in communication can blow up quite quickly.

I burnt out in my late 20s.

My greatest fear has been something I’ve always referred to as “the big alone”. Even when I’ve been in loving relationships, as I am now, there has been a terrible aloneness in not understanding why I am not like other people.

I was able to look back at situations and misunderstandings and understand what had happened. I’d been told my communication could be “off” sometimes – a bit intense, a bit abrupt.

Autistic children spend a lot of time “masking”, imitating so-called “normal” behaviour. They need to be able to experience their authentic selves.

Over the past five or 10 years, the concept of neurodiversity – the idea that these differences in our brains should be celebrated – has become better known. We deserve equality, respect and full social inclusion.

We need to start making space for neurodivergent people at school, at work, in life generally. Autistic people bring a whole new set of skills with them.
