Opinion | What Are Republicans So Afraid Of? - The New York Times - 0 views

  • What Are Republicans So Afraid Of?
  • Instead of conspiracy-mongering about an election they did well in, they could try to win real majorities.
  • There was a time, in recent memory, when the Republican Party both believed it could win a national majority and actively worked to build one.
  • ...13 more annotations...
  • Whether shrewd or misguided, cynical or sincere — or outright cruel and divisive — these gambits were each part of an effort to expand the Republican coalition as far as it could go without abandoning Reaganite conservatism itself.
  • It was the work of a self-assured political movement, confident that it could secure a position as the nation’s de facto governing party.
  • There is no such ambition, or confidence, in today’s Republican Party.
  • Republicans have made it their mission to restrict the vote as much as possible.
  • Conservative grass-roots and political action groups are joining the crusade, according to reporting by my newsroom colleague Jeremy Peters, galvanized into action by the former president, who blames nonexistent fraud and illegal voting for his defeat.
  • “So here’s the good news: There is action taking place to go back and correct what was uncovered in this last election.”
  • “It kind of feels like an all-hands-on-deck moment for the conservative movement, when the movement writ large realizes the sanctity of our elections is paramount and voter distrust is at an all-time high,”
  • H.R. 1’s only objective is to ensure that Democrats can never again lose another election, that they will win and maintain control of the House of Representatives and the Senate and of the state legislatures for the next century,”
  • Some of this is undoubtedly cynical, a brazen attempt to capitalize on the conspiratorial rhetoric of the former president. But some of it is sincere, a genuine belief that the Republican Party will cease to exist if it cannot secure “election integrity.”
  • If Republicans could break themselves of Trump and look at last November with clear eyes, they would see that their fears of demographic eclipse are overblown and that they can compete — even thrive — in the kinds of high-turnout elections envisioned by voting rights activists.
  • Indeed, the great irony of the Republican Party’s drive to restrict the vote in the name of Trump is that it burdens the exact voters he brought to the polls.
  • Under Trump, the Republican Party swapped some of the most likely voters — white college-educated moderates — for some of the least likely — blue-collar men.
  • In other words, by killing measures that make voting more open to everyone, Republicans might make their fears of terminal decline a self-fulfilling prophecy.

You're more biased than you think - even when you know you're biased | News | The Guardian - 0 views

  • there’s plenty of evidence to suggest that we’re all at least somewhat subject to bias
  • Tell Republicans that some imaginary policy is a Republican one, as the psychologist Geoffrey Cohen did in 2003, and they’re much more likely to support it, even if it runs counter to Republican values. But ask them why they support it, and they’ll deny that party affiliation played a role. (Cohen found something similar for Democrats.

  • Even when the risk of bias was explicitly pointed out to them, people remained confident that they weren’t susceptible to it
  • “Even when people acknowledge that what they are about to do is biased,” the researchers write, “they still are inclined to see their resulting decisions as objective.”
  • we have a cognitive bias to the effect that we’re uniquely immune to cognitive biases.
  • It turns out the bias also applies to bias. In other words, we’re convinced that we’re better than most at not falling victim to bias.
  • “used a strategy that they thought was biased,” the researchers note, “and thus they probably expected to feel some bias when using it. The absence of that feeling may have made them more confident in their objectivity.”
  • why it’s often better for companies to hire people, or colleges to admit students, using objective checklists, rather than interviews that rely on gut feelings.
  • Bias spares nobody.

What a 16th-Century Mystic Can Teach Us About Making Good Decisions - 1 views

  • Among the many decision-making methods for life’s big decisions, one that stands out is from an early 16th-century soldier-turned-mystic, St. Ignatius of Loyola.
  • Ignatius uses the language of faith, but, I believe, anyone can apply his method to make more informed decisions.
  • 1. Rely on Reason and Feelings
  • ...19 more annotations...
  • Ignatius advises creating a list, but also takes it a step further by urging people to listen to their feelings as they consider the pros and cons for each option.
  • he asks individuals to consider: Do some pros or cons stand out because they bring you a sense of peace, joy or hope? Or feelings of dread, anxiety or despair?
  • He advises probing the origin of the feelings to find out if they come, for example, from desires for power or greed, fear of what others may think, a desire to do good or to be selfless.
  • Ignatius teaches that freedom from attachment to a particular choice or outcome is essential
  • Ignatius also advises that individuals share their deliberations with a confidant, advice that he followed when making his own decisions.
  • the process of sharing emotions with others helps make sense of our thoughts and feelings.
  • Ignatius advises individuals to act on reason, feeling confident that they have invested their time and energy to make a good choice.
  • How can non-religious people use this advice? I argue they can consider how their decisions will affect the vulnerable, the poorest and the most marginalized
  • 2. Imaginative Reflection
  • Ignatius offers three imaginative exercises if no clear choice emerges:
  • Imagine that a friend comes to you with the same situation
  • Imagine that you are on your deathbed
  • Imagine a conversation with the divine
  • 3. Seek Confirmation
  • He also urged people to make decisions for the “greater glory of God.”
  • The emotions they feel following a decision, such as peace, freedom, joy, love or compassion, might give an indication if it is the right choice.
  • He realized that pursuing worldly honor was not as fulfilling as doing the work of God.
  • In today’s hurried world, a 16th-century Catholic mystics’ advice may seem quaint or his process tedious. However, many modern psychological approaches confirm the value of such reflective practices.
  • Imaginative reflections like these offer clarity to decision-making by providing another perspective to the decision at hand.

Google's Relationship With Facts Is Getting Wobblier - The Atlantic - 0 views

  • Misinformation or even disinformation in search results was already a problem before generative AI. Back in 2017, The Outline noted that a snippet once confidently asserted that Barack Obama was the king of America.
  • This is what experts have worried about since ChatGPT first launched: false information confidently presented as fact, without any indication that it could be totally wrong. The problem is “the way things are presented to the user, which is Here’s the answer,” Chirag Shah, a professor of information and computer science at the University of Washington, told me. “You don’t need to follow the sources. We’re just going to give you the snippet that would answer your question. But what if that snippet is taken out of context?”
  • Responding to the notion that Google is incentivized to prevent users from navigating away, he added that “we have no desire to keep people on Google.
  • ...15 more annotations...
  • Pandu Nayak, a vice president for search who leads the company’s search-quality teams, told me that snippets are designed to be helpful to the user, to surface relevant and high-caliber results. He argued that they are “usually an invitation to learn more” about a subject
  • “It’s a strange world where these massive companies think they’re just going to slap this generative slop at the top of search results and expect that they’re going to maintain quality of the experience,” Nicholas Diakopoulos, a professor of communication studies and computer science at Northwestern University, told me. “I’ve caught myself starting to read the generative results, and then I stop myself halfway through. I’m like, Wait, Nick. You can’t trust this.”
  • Nayak said the team focuses on the bigger underlying problem, and whether its algorithm can be trained to address it.
  • If Nayak is right, and people do still follow links even when presented with a snippet, anyone who wants to gain clicks or money through search has an incentive to capitalize on that—perhaps even by flooding the zone with AI-written content.
  • Nayak told me that Google plans to fight AI-generated spam as aggressively as it fights regular spam, and claimed that the company keeps about 99 percent of spam out of search results.
  • The result is a world that feels more confused, not less, as a result of new technology.
  • The Kenya result still pops up on Google, despite viral posts about it. This is a strategic choice, not an error. If a snippet violates Google policy (for example, if it includes hate speech) the company manually intervenes and suppresses it, Nayak said. However, if the snippet is untrue but doesn’t violate any policy or cause harm, the company will not intervene.
  • experts I spoke with had several ideas for how tech companies might mitigate the potential harms of relying on AI in search
  • For starters, tech companies could become more transparent about generative AI. Diakopoulos suggested that they could publish information about the quality of facts provided when people ask questions about important topics
  • They can use a coding technique known as “retrieval-augmented generation,” or RAG, which instructs the bot to cross-check its answer with what is published elsewhere, essentially helping it self-fact-check. (A spokesperson for Google said the company uses similar techniques to improve its output.) They could open up their tools to researchers to stress-test it. Or they could add more human oversight to their outputs, maybe investing in fact-checking efforts.
  • Fact-checking, however, is a fraught proposition. In January, Google’s parent company, Alphabet, laid off roughly 6 percent of its workers, and last month, the company cut at least 40 jobs in its Google News division. This is the team that, in the past, has worked with professional fact-checking organizations to add fact-checks into search results
  • Alex Heath, at The Verge, reported that top leaders were among those laid off, and Google declined to give me more information. It certainly suggests that Google is not investing more in its fact-checking partnerships as it builds its generative-AI tool.
  • Nayak acknowledged how daunting a task human-based fact-checking is for a platform of Google’s extraordinary scale. Fifteen percent of daily searches are ones the search engine hasn’t seen before, Nayak told me. “With this kind of scale and this kind of novelty, there’s no sense in which we can manually curate results.”
  • Creating an infinite, largely automated, and still accurate encyclopedia seems impossible. And yet that seems to be the strategic direction Google is taking.
  • A representative for Google told me that this was an example of a “false premise” search, a type that is known to trip up the algorithm. If she were trying to date me, she argued, she wouldn’t just stop at the AI-generated response given by the search engine, but would click the link to fact-check it.

Lockheed Martin Harnesses Quantum Technology - NYTimes.com - 0 views

  • academic researchers and scientists at companies like Microsoft, I.B.M. and Hewlett-Packard have been working to develop quantum computers.
  • Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business.
  • if it performs as Lockheed and D-Wave expect, the design could be used to supercharge even the most powerful systems, solving some science and business problems millions of times faster
  • ...8 more annotations...
  • It could be possible, for example, to tell instantly how the millions of lines of software running a network of satellites would react to a solar burst or a pulse from a nuclear explosion — something that can now take weeks, if ever, to determine.
  • “This is a revolution not unlike the early days of computing,” he said. “It is a transformation in the way computers are thought about.”
  • quantum computing relies on the fact that subatomic particles inhabit a range of states. Different relationships among the particles may coexist, as well. Those probable states can be narrowed to determine an optimal outcome among a near-infinitude of possibilities, which allows certain types of problems to be solved rapidly.
  • Mr. Brownell, who joined D-Wave in 2009, was until 2000 the chief technical officer at Goldman Sachs. “In those days, we had 50,000 servers just doing simulations” to figure out trading strategies, he said. “I’m sure there is a lot more than that now, but we’ll be able to do that with one machine, for far less money.”
  • If Microsoft’s work pans out, he said, the millions of possible combinations of the proteins in a human gene could be worked out “fairly easily.”
  • Quantum computing has been a goal of researchers for more than three decades, but it has proved remarkably difficult to achieve. The idea has been to exploit a property of matter in a quantum state known as superposition, which makes it possible for the basic elements of a quantum computer, known as qubits, to hold a vast array of values simultaneously.
  • There are a variety of ways scientists create the conditions needed to achieve superposition as well as a second quantum state known as entanglement, which are both necessary for quantum computing. Researchers have suspended ions in magnetic fields, trapped photons or manipulated phosphorus atoms in silicon.
  • In the D-Wave system, a quantum computing processor, made from a lattice of tiny superconducting wires, is chilled close to absolute zero. It is then programmed by loading a set of mathematical equations into the lattice. The processor then moves through a near-infinity of possibilities to determine the lowest energy required to form those relationships. That state, seen as the optimal outcome, is the answer.

  • We are hurried and distracted and don’t pay close attention to what we are doing. Often, we turn over our data in exchange for a deal we can’t refuse.
  • his research argues that when it comes to privacy, policy makers should carefully consider how people actually behave. We don’t always act in our own best interest, his research suggests. We can be easily manipulated by how we are asked for information. Even something as simple as a playfully designed site can nudge us to reveal more of ourselves than a serious-looking one.
  • “His work has gone a long way in trying to help us figure out how irrational we are in privacy related decisions,” says Woodrow Hartzog, an assistant professor of law who studies digital privacy at Samford University in Birmingham, Ala. “We have too much confidence in our ability to make decisions.”

  • Solutions to our leaky privacy system tend to focus on transparency and control — that our best hope is knowing what our data is being used for and choosing whether to participate. But a challenge to that conventional wisdom emerges in his research. Giving users control may be an essential step, but it may also be a bit of an illusion.
  • personal data is what fuels the barons of the Internet age. Mr. Acquisti investigates the trade-offs that users make when they give up that data, and who gains and loses in those transactions. Often there are immediate rewards (cheap sandals) and sometimes intangible risks downstream (identity theft). “
  • “The technologist in me loves the amazing things the Internet is allowing us to do,” he said. “The individual who cares about freedom is concerned about the technology being hijacked, from a technology of freedom into a technology of surveillance.”
  • EARLY in his sojourn in this country, Mr. Acquisti asked himself a question that would become the guiding force of his career: Do Americans value their privacy?
  • If we have something — in this case, ownership of our purchase data — we are more likely to value it. If we don’t have it at the outset, we aren’t likely to pay extra to acquire it. Context matters.
  • “What worries me,” he said, “is that transparency and control are empty words that are used to push responsibility to the user for problems that are being created by others.”
  • We are constantly asked to make decisions about personal data amid a host of distractions, like an e-mail, a Twitter notification or a text message. If Mr. Acquisti is correct, those distractions may hinder our sense of self-protection when it comes to privacy.
  • His latest weapon against distraction is an iPad application, which lets him create a to-do list every morning and set timers for each task: 30 minutes for e-mail, 60 minutes to grade student papers, and so on.
  • it is not surprising that he is cautious in revealing himself online. He says he doesn’t feel compelled to post a picture of his meals on Instagram. He uses different browsers for different activities. He sometimes uses tools that show which ad networks are tracking him. But he knows he cannot hide entirely, which is why some people, he says, follow a policy of “rational ignorance.”
  • The online advertising industry insists that the data is scrambled to make it impossible to identify individuals.
  • Mr. Acquisti offers a sobering counterpoint. In 2011, he took snapshots with a webcam of nearly 100 students on campus. Within minutes, he had identified about one-third of them using facial recognition software. In addition, for about a fourth of the subjects whom he could identify, he found out enough about them on Facebook to guess at least a portion of their Social Security numbers.
  • The point of the experiment was to show how easy it is to identify people from the rich trail of data they scatter around the Web, including seemingly harmless pictures. Facebook can be especially valuable for identity thieves, particularly when a user’s birth date is visible to the public.
  • Does that mean Facebook users should lie about their birthdays (and break Facebook’s terms of service)? Mr. Acquisti demurred. He would say only that there are “complex trade-offs” to be made. “I reveal my date of birth and hometown on my Facebook profile and an identity thief can reconstruct my Social Security number and steal my identity,” he said, “or someone can send me ‘happy birthday’ messages on the day of my birthday, which makes me feel very good.”

The Signal and the Noise: Why So Many Predictions Fail-but Some Don't: Nate Silver: 978... - 0 views

  • Nate Silver built an innovative system for predicting baseball performance, predicted the 2008 election within a hair’s breadth, and became a national sensation as a blogger—all by the time he was thirty. The New York Times now publishes FiveThirtyEight.com, where Silver is one of the nation’s most influential political forecasters.
  • Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the “prediction paradox”: The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.
  • the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.

  • This is the best general-readership book on applied statistics that I've read. Short review: if you're interested in science, economics, or prediction: read it. It's full of interesting cases, builds intuition, and is a readable example of Bayesian thinking.
  • The core concept is this: prediction is a vital part of science, of business, of politics, of pretty much everything we do. But we're not very good at it, and fall prey to cognitive biases and other systemic problems such as information overload that make things worse. However, we are simultaneously learning more about how such things occur and that knowledge can be used to make predictions better -- and to improve our models in science, politics, business, medicine, and so many other areas.

  • Nobody is saying that injuries are good, or that girls should be reckless. But risk taking is important
  • It follows that by cautioning girls away from these experiences, we are not protecting them. We are failing to prepare them for life.
  • When a girl learns that the chance of skinning her knee is an acceptable reason not to attempt the fire pole, she learns to avoid activities outside her comfort zone.
  • Fear becomes a go-to feminine trait, something girls are expected to feel and express at will.
  • By the time a girl reaches her tweens no one bats an eye when she screams at the sight of an insect.
  • When girls become women, this fear manifests as deference and timid decision making
  • We must chuck the insidious language of fear (Be careful! That’s too scary!) and instead use the same terms we offer boys, of bravery and resilience. We need to embolden girls to master skills that at first appear difficult, even dangerous. And it’s not cute when a 10-year-old girl screeches, “I’m too scared.”
  • I was often scared. Of course I was. So were the men.

No matter who wins the presidential election, Nate Silver was right - The Washington Post - 1 views

  • I don’t fault Silver for his caution. It’s honest. What it really says is he doesn’t know with much confidence what’s going to happen
  • That’s because there’s a lot of human caprice and whim in electoral behavior that can’t always be explained or predicted with scientific precision. Politics ain’t moneyball. Good-quality polls give an accurate sense of where a political race is at a point in time, but they don’t predict the future.
  • Predictive models, generally based on historical patterns, work until they don’t.

  • In his hedged forecasts this time, Silver appears to be acknowledging that polling and historical patterns don’t always capture what John Maynard Keynes, in his classic 1936 economic General Theory, described as “animal spirits.”
  • There is, Keynes wrote, “the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as a result of animal spirits — of a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.”

The Obama legacy that can't be repealed - The Washington Post - 0 views

  • There is no mystery about Barack Obama’s greatest presidential achievement: He stopped the Great Recession from becoming the second Great Depression. True, he had plenty of help, including from his predecessor, George W. Bush, and from the top officials at the Treasury Department and Federal Reserve. But if Obama had made one wrong step, what was a crushing economic slump could have become something much worse.
  • It is Obama’s unfortunate fate that the high-water mark of his presidency occurred in the first months, when the world flirted with financial calamity. The prospect of another Great Depression — a long period of worsening economic decline — was not far-fetched.
  • In the first quarter of 2009, as Obama was moving into the White House, monthly job losses averaged 772,000. The ultimate decline in employment was 8.7 million jobs, or 6.3 percent. Housing prices and stock values were collapsing. From their peak in February 2007 to their low point, housing prices dropped 26 percent. Millions of homeowners were “underwater” — their houses were worth less than the mortgages on them. Stock prices fell roughly by half from August 2007 to March 2009.

  • There was no guarantee that the economy’s downward spiral wouldn’t continue, as frightened businesses and consumers curbed spending and, in the process, increased unemployment. The CEA presents a series of charts comparing the 2008-2009 slump with the Great Depression. In every instance, the 2008-2009 downturn was as bad as — or worse than — the first year of the Great Depression: employment loss, drop in global trade and change in households’ net worth.
  • The starkest of these was the fall in households’ net worth (people’s assets, such as homes and stock, minus their debts, such as mortgages and credit-card balances). It dropped by $13 trillion, about a fifth, from its high point in 2007 to its trough in 2009. This decline, the CEA notes, “was far larger than the reduction [adjusted for inflation] . . . at the onset of the Great Depression.”
  • What separates then from now is that, after 18 months or so, spending turned up in 2009 while it continued declining in the 1930s. This difference reflected, at least in part, the aggressive policies adopted to blunt the downturn. The Fed cut short-term interest rates to zero and provided other avenues of cheap credit; the Troubled Asset Relief Program (TARP), enacted in the final months of the Bush administration, poured money into major banks to reassure the public of their solvency.
  • Still, Obama’s role was crucial. Against opposition, he decided to rescue General Motors and Chrysler. Throwing them onto the tender mercies of the market would have been a huge blow to the industrial Midwest and to national psychology. He also championed a sizable budget “stimulus.” Advertised originally as $787 billion, it was actually $2.6 trillion over four years when the initial program was combined with later proposals and so-called “automatic stabilizers” are included, the CEA says
  • More generally, Obama projected reason and calm when much of the nation was fearful and frazzled. Of course, he didn’t single-handedly restore confidence, but he made a big contribution
  • the recovery from the Great Recession is mostly complete. This seems plausible. Since the low point, employment is up 15.6 million jobs. Rising home and stock prices have boosted inflation-adjusted household net worth by 16 percent. Gross domestic product — the economy — is nearly 12 percent higher than before the financial crisis
  • his impact is underestimated. Suppose we had had a second Great Depression with, say, peak unemployment of 15 percent. Almost all our problems — from poverty to political polarization — would have worsened. Obama’s influence must be considered in this context. When historians do, they may be more impressed.

Unbelievable: Why Americans Mistrust Science | SciBytes | Learn Science at Scitable - 0 views

  • 25% of American respondents answered that the sun orbits the Earth [1]. A recent AP-GFK poll found that as many as 4 in 10 American adults doubt evolution, over half aren't confident that the Big Bang took place, just under 40% don't believe that pollution is causing climate change
  • When teaching science, teachers have to contend with students' old ideas of how the world works, an uphill battle where the old ideas have the advantage.
  • Children are exposed to scientific ideas at around age eight, when they become able to understand abstract concepts. Before that age, children rely on "magical thinking" to explain how the world exists and works, so, science education faces a tough challenge right from the start
  •  
    Interesting - before the age of 8 most children are unable to understand very abstract concepts and resort to forming ideas that make sense symbolically to them - "magical thinking." So we do not have fundamentally "scientific" minds, and instead must rewrite our preconceived notions.  (Evie - 12/6/16)

Most Americans believe Donald Trump is incapable of dealing with an international crisis - 1 views

  •  
    A majority of Americans lack confidence in Donald Trump's ability to handle an international crisis, according to a new poll. It also found 47 per cent doubted his ability to use military force wisely. Ahead of the President-elect's inauguration on 20 January, 44 per cent believed him to be incapable of averting major scandals during his time in office. I thought that this was interesting because despite many people's doubts, he was still elected president.

We should look beyond economics and open our eyes to beauty | Fiona Reynolds | Opinion ... - 0 views

  • Yet you’d be hard pressed to find the word in any official document, or to hear any politician utter it today. In fact we seem almost embarrassed to talk about beauty, other than in private. Instead we have invented all kinds of pseudo, management-speak words to describe the things we need to look after: words like ecosystem services, natural capital and sustainable development
  • But it wasn’t always like that. Beauty was a word and an idea that people in previous centuries used freely and confidently, including in legislation and public policy. And because people celebrated beauty it was something they sought to create, in town and country, and enacted laws to protect the things and places people loved.
  • Beauty is written deeply into our culture. Some of the earliest texts show a yearning for beauty, with Chaucer reminding us that it was the beauty of an April spring that “longen folk to goon on pilgrimages”. Medieval stonemasons constructed fabulous churches and cathedrals, carving flowers and animals into their stone.

A Better Way to Teach Math - NYTimes.com - 2 views

  • “Almost every kid — and I mean virtually every kid — can learn math at a very high level, to the point where they could do university level math courses,”
  • “If you ask why that’s not happening, it’s because very early in school many kids get the idea that they’re not in the smart group, especially in math. We kind of force a choice on them: to decide that either they’re dumb or math is dumb.”
  • In particular, math teachers often fail to make sufficient allowances for the limitations of working memory and the fact that we all need extensive practice to gain mastery in just about anything.

  • current teaching approaches underestimate the amount of explicit guidance, “scaffolding” and practice children need to consolidate new concepts. Asking children to make their own discoveries before they solidify the basics is like asking them to compose songs on guitar before they can form a C chord.
  • he gained a reputation as a kind of math miracle worker. Many students were sent to him because they had severe learning disabilities (a number have gone on to do university-level math). Mighton found that to be effective he often had to break things down into minute steps and assess each student’s understanding at each micro-level before moving on.
  • Mighton saw that if he approached teaching this way, he could virtually guarantee that every student would experience success. In turn, the children’s math anxiety diminished. As they grew more confident, they grew excited, and they began requesting harder challenges. “More than anything, kids love success,” he says, “and they love getting to higher levels, like in a video game.”
  • Mighton saw that if you provided painstaking guidance, children would make their own discoveries. That’s why he calls his approach “guided discovery.”
  • Schools in British Columbia evaluate students based on whether they meet expectations for learning outcomes. “Teachers who used Jump were suddenly finding that they had all of their kids in the ‘fully meeting expectations’ category,” Grant told me. “It was such a foreign experience. It doesn’t typically happen when we’re teaching science or language arts. And they were kind of at a loss. ‘What do we do about this?’”
  • Even deeper, for children, math looms large; there’s something about doing well in math that makes kids feel they are smart in everything. In that sense, math can be a powerful tool to promote social justice. “When you have all the kids in a class succeeding in a subject, you see that they’re competing against the problem, not one another,” says Mighton. “It’s like they’re climbing a mountain together. You see a very healthy kind of competition. And it makes kids more generous to one another. Math can save us.”
