While people can improve their recall through tricks and practice, eidetikers are born, not made, says Searleman. The ability isn't linked to other traits, such as high intelligence. Children are more likely to possess eidetic memory than adults, though they begin losing the ability after age six as they learn to process information more abstractly.

Although psychologists don't know why children lose the ability, the loss of this skill may be functional: Were humans to remember every single image, it would be difficult to make it through the day.

He hypothesizes that the process involves one or more molecules released by the nervous system — perhaps small RNAs, perhaps something secreted like a hormone. But somehow those germ cells then influence the behavior of the next generation and seem to circumvent the normal need for rde-4 in the production of the small RNAs for chemotaxis in the progeny.

“I believe that today, there is not a single solid paper showing that only small RNAs are involved in epigenetic inheritance,” said Isabelle Mansuy, a neuroepigenetics researcher at the Swiss Federal Institute of Technology Zurich and the University of Zurich who studies the inheritance of trauma in humans and mice. In the mouse model she works with, she knows that small RNAs are not sufficient because if she injects small RNAs alone into fertilized mouse eggs, the resulting animals do not show the RNA-associated trait.

“If we can ingest a chemical from our environment that changes the epigenomes of the egg or sperm, why couldn’t our brain make a similar molecule that does the same thing?”

Although three million miles sounds vast, it’s not much on the scale of our solar system. In fact, despite the planet’s elliptical path through the heavens, most astronomers say that Earth’s orbit is basically circular. On a scale of 0 to 100 percent, where 0 is a perfect circle and nearly 100 is a very thin oval, Earth only scores a 1.7.

It’s a defining trait that keeps our planet at roughly the same distance from our sun, and keeps the climate relatively stable. This has led many astronomers to wonder whether a circular orbit just might be a crucial ingredient in the cocktail of life — and a key factor to consider as they search for signs of alien life around the thousands of exoplanets known to be circling other stars within the galaxy.

Such a dire portrait could suggest that life prefers a circle. But do most exoplanets orbit their host stars in bands similar to the Earth, or are their orbits more like that of HD 20782 b?

Consider the exoplanet known as HD 20782 b, which boasts the highest eccentricity yet discovered — a whopping 97 percent. Although the alien world is likely more akin to Jupiter than Earth in mass, it’s easy to imagine what might happen to a wildly eccentric Earthlike planet.At its closest approach to the star, the planet would face an explosion of heat that would evaporate the planet’s oceans and strip the planet’s atmosphere, sending crucial molecules such as oxygen streaming into space.

This suggests that most of these rocky worlds might be able to host a stable climate and, therefore, life.But Dr. Kane and other researchers warned against dismissing the possibility of life forming on worlds with highly-eccentric orbits.

Last year, Dr. Kane and his colleagues estimated that a planet with an eccentricity as high as 30 or even 40 percent could remain habitable

the galaxy and its many orbiting planets could surprise us. “I think it’s often assumed that life is wimpy and needs ‘just so’ conditions to exist,” Dr. Raymond said. “But life on Earth did indeed survive some tough times.”

"People who are more socially connected to family, to friends, to community, are happier, they're physically healthier, and they live longer than people who are less well connected," said Harvard psychiatrist Robert Waldinger in his popular TEDx talk. "And the experience of loneliness turns out to be toxic."

The lessons aren't about wealth or fame or working harder and harder," Waldinger said. "The clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier. Period."

"In fact, the more positive the person, the greater the protection from heart attacks, stroke and any cause of death," said Mt. Sinai's Rozanski, who was the lead author on the study.

A sense of purpose and meaning in your life is a big part of living a longer, happier life, according to psychology professor Lyle Ungar, who has developed what he calls the Well-Being Map. It rates every US county on such psychological factors as openness, trust, agreeableness and neuroticism.

"If your sole duty is to achieve the best for yourself, life becomes just too stressful, too lonely -- you are set up to fail. Instead, you need to feel you exist for something larger, and that very thought takes off some of the pressure."

SpiritualityStudies by the Pew Research Center show that actively religious people are more likely than less- or non-religious people to describe themselves as "very happy." They also share some traits that could improve their chance at a longer, happy life: They are less likely to smoke and drink, and more likely to join clubs and volunteer at charities.

"I'm surprised how good religion is for people," Ungar said. "Religious people are more agreeable, they're happier, they live longer."It doesn't have to be a traditional religion. Layard points out that spiritual practices ranging from meditation to positive psychology to cognitive therapy can also feed an inner life.

The simple framework that Haaland and Botero describe can be applied to any kind of environmental extreme including flooding, wildfires, heatwaves, droughts, cold spells, tornadoes and hurricanes -- any and all of which might be considered part of the "new normal" under climate change.

"Our results challenge the idea that species that have been historically exposed to more variable environments are better suited to cope with climate change," Botero said.

"In this case, our model suggests that the typical inhabitants of these places are likely to be more vulnerable to hotter temperatures than to longer or more widespread heat waves."

"While this simple conservation action is unlikely to completely shift the balance from a 'conservative' to a 'care-free' evolutionary response to extreme events, it may nevertheless reduce the strongest vulnerability of these 'conservative' lizard populations," Botero said. "It might just buy them enough time to accumulate sufficient evolutionary changes in their toes and limbs to meet the new demands of their altered habitat."

It’s well-known that most of the emails are composed by nonnative speakers of English, as is clear from the many grammatical and punctuation mistakes, broken syntax, missing words, and malapropisms (“the will to personify the façade to its practical conclusion” for “pursue the charade”). With so many mistakes, how can this language really fool anyone? Often, victims know the message comes from a nonnative speaker, or they may be nonnative English speakers themselves and may not always recognize grammatical errors.

The scammers make extraordinary efforts to use technical, military, financial or otherwise professional language in a clumsy caricature of what formal, educated English sounds like (“government officials . . . awarded themselves contracts that were grossly over-invoiced in various ministries and parastatals”) to keep up the pretence of being a barrister, a brigadier-general, or a bank official.

It’s a simple scam, but appears to be effective when it reaches credulous types who are willing to ignore the warning signs in search of a treasure hunting adventure that can make a life extraordinary for a while, before it all ends in grief.

Graduate students will inevitably encounter failed experiments, failed teachable moments in the classroom, and time spent on research that never gets funded or never comes to fruition. Wilson counsels patience: “A strong work ethic is absolutely essential. There must be an ability to pass long hours in study and research with pleasure even though some of the effort will inevitably lead to dead ends.”

Scientists, he claims, tend to be introverted and prone to daydreaming. They reject authority and therefore dislike being told what to do. Their attention wanders. This pigeonholing made me uncomfortable, because I think science benefits from incorporating a diversity of personalities

So I didn’t celebrate his death as so many have, and frankly it pains me to read that stuff because it’s as cruel as he was

there is perhaps no other human who did more to lower the civility of public discourse, and who gave license to others to do the same. He became a truly disgusting broadcaster.

Dr. Byrne and her colleagues measured risky decision-making by presenting people with a gambling scenario. They could choose between two bets: One offered a guaranteed amount of money, while the other offered the possibility of a larger amount of money but also the possibility of receiving no cash. A different exercise measured people’s preference for immediate versus delayed rewards: Participants could choose a certain amount of money now, or a larger amount later.

Study subjects also reported Covid-19 precautions they had taken in their daily lives, including masking and social distancing.

with Covid-19, people don’t feel sick immediately after an exposure so the benefits of wearing a mask, social distancing or getting vaccinated aren’t immediately apparent. “You don’t see the lives you potentially save,” she says

“People generally are more motivated by immediate gratification or immediate benefits rather than long-term benefits, even when the long-term benefits are much greater,

Research has also found being extroverted or introverted affects how people make decisions about Covid-19 precautions. A recent study of more than 8,500 people in Japan published in the journal PLOS One in October 2020 found that those who scored high on a scale of extraversion were 7% less likely to wear masks in public and avoid large gatherings, among other precautions.

The study also found that people who scored high on a measure of conscientiousness—valuing hard work and achievement—were 31% more likely to follow Covid-19 public-health precautions.

Scientists believe that a person’s propensity to take risks is partly genetic and partly the result of early life experiences

Certain negative childhood experiences including physical, emotional or sexual abuse, parental divorce, or living with someone who was depressed or abused drugs or alcohol are linked to risky behavior in adulthood like smoking and drinking heavily, other research has found.

Studies of twins have generally found that about 30% of the difference in individual risk tolerance is genetic

And scientists have discovered that the brains of people who are more willing to take risks look different than those of people who are more cautious.

ambling task had differences in the structure and function of the amygdala, a part of the brain involved in detecting threats, and the prefrontal cortex, a region involved in executive

Even people who have the same information and a similar perception of the risks may make different decisions because of the ways they interpret the information. When public-health officials talk about breakthrough infections in vaccinated individuals being rare, for example, “rare means different things” to different people

The researchers used facial-recognition software to map out specific points on a person’s face, then applied machine-learning algorithms to the facial points to obtain empirical measures for three key face impressions—trustworthiness, dominance and attractiveness.  

They examined the association of these impressions with the accuracy of analysts’ quarterly forecasts, drawn from the Institutional Brokers Estimate System

Analyst accuracy was determined by comparing each analyst’s prediction error—the difference between their prediction and the actual earnings—with that of all analysts for that same company and quarter.

For an average stock valued at $100, Prof. Teoh says, analysts ranked as looking most trustworthy were 25 cents more accurate in earnings-per-share forecasts than the analysts who were ranked as looking least trustworthy

Similarly, most-dominant-looking analysts were 52 cents more accurate in their EPS forecast than least-dominant-looking analysts.

The relation between a dominant face and accuracy, meanwhile, was significant before and after the regulation was enacted, the analysts say. This suggests that dominant-looking male analysts are always able to obtain information,

While forecasts of female analysts regardless of facial characteristics were on average more accurate than those of their male counterparts, the forecasts of women who were seen as more-dominant-looking were significantly less accurate than their male counterparts.  

Says Prof. Todorov: “Women who look dominant are more likely to be viewed negatively because it goes against the cultural stereotype.

The philosopher Immanuel Kant (1724–1804) argued in his Critique of Pure Reason that the human mind knows objects in innate, a priori ways. Kant claimed that humans, from birth, must experience all objects as being successive (time) and juxtaposed (space). His list of inborn categories describes predicates that the mind can attribute to any object in general. Arthur Schopenhauer (1788–1860) agreed with Kant, but reduced the number of innate categories to one—causality—which presupposes the others.

Modern nativism is most associated with the work of Jerry Fodor (1935–2017), Noam Chomsky (b. 1928), and Steven Pinker (b. 1954), who argue that humans from birth have certain cognitive modules (specialised genetically inherited psychological abilities) that allow them to learn and acquire certain skills, such as language.

For example, children demonstrate a facility for acquiring spoken language but require intensive training to learn to read and write. This poverty of the stimulus observation became a principal component of Chomsky's argument for a "language organ"—a genetically inherited neurological module that confers a somewhat universal understanding of syntax that all neurologically healthy humans are born with, which is fine-tuned by an individual's experience with their native language

In The Blank Slate (2002), Pinker similarly cites the linguistic capabilities of children, relative to the amount of direct instruction they receive, as evidence that humans have an inborn facility for speech acquisition (but not for literacy acquisition).

A number of other theorists[1][2][3] have disagreed with these claims. Instead, they have outlined alternative theories of how modularization might emerge over the course of development, as a result of a system gradually refining and fine-tuning its responses to environmental stimuli.[4]

Many empiricists are now also trying to apply modern learning models and techniques to the question of language acquisition, with marked success.[20] Similarity-based generalization marks another avenue of recent research, which suggests that children may be able to rapidly learn how to use new words by generalizing about the usage of similar words that they already know (see also the distributional hypothesis).[14][21][22][23]

The term universal grammar (or UG) is used for the purported innate biological properties of the human brain, whatever exactly they turn out to be, that are responsible for children's successful acquisition of a native language during the first few years of life. The person most strongly associated with the hypothesising of UG is Noam Chomsky, although the idea of Universal Grammar has clear historical antecedents at least as far back as the 1300s, in the form of the Speculative Grammar of Thomas of Erfurt.

This evidence is all the more impressive when one considers that most children do not receive reliable corrections for grammatical errors.[9] Indeed, even children who for medical reasons cannot produce speech, and therefore have no possibility of producing an error in the first place, have been found to master both the lexicon and the grammar of their community's language perfectly.[10] The fact that children succeed at language acquisition even when their linguistic input is severely impoverished, as it is when no corrective feedback is available, is related to the argument from the poverty of the stimulus, and is another claim for a central role of UG in child language acquisition.

Researchers at Blue Brain discovered a network of about fifty neurons which they believed were building blocks of more complex knowledge but contained basic innate knowledge that could be combined in different more complex ways to give way to acquired knowledge, like memory.[11

experience, the tests would bring about very different characteristics for each rat. However, the rats all displayed similar characteristics which suggest that their neuronal circuits must have been established previously to their experiences. The Blue Brain Project research suggests that some of the "building blocks" of knowledge are genetic and present at birth.[11]

modern nativist theory makes little in the way of specific falsifiable and testable predictions, and has been compared by some empiricists to a pseudoscience or nefarious brand of "psychological creationism". As influential psychologist Henry L. Roediger III remarked that "Chomsky was and is a rationalist; he had no uses for experimental analyses or data of any sort that pertained to language, and even experimental psycholinguistics was and is of little interest to him".[13]

, Chomsky's poverty of the stimulus argument is controversial within linguistics.[14][15][16][17][18][19]

Neither the five-year-old nor the adults in the community can easily articulate the principles of the grammar they are following. Experimental evidence shows that infants come equipped with presuppositions that allow them to acquire the rules of their language.[6]

Paul Griffiths, in "What is Innateness?", argues that innateness is too confusing a concept to be fruitfully employed as it confuses "empirically dissociated" concepts. In a previous paper, Griffiths argued that innateness specifically confuses these three distinct biological concepts: developmental fixity, species nature, and intended outcome. Developmental fixity refers to how insensitive a trait is to environmental input, species nature reflects what it is to be an organism of a certain kind, and the intended outcome is how an organism is meant to develop.[24]

While people praised Finland’s strong social safety net and spoke glowingly of the psychological benefits of nature and the personal joys of sports or music, they also talked about guilt, anxiety and loneliness. Rather than “happy,” they were more likely to characterize Finns as “quite gloomy,” “a little moody” or not given to unnecessary smiling

Many also shared concerns about threats to their way of life, including possible gains by a far-right party in the country’s elections in April, the war in Ukraine and a tense relationship with Russia, which could worsen now that Finland is set to join NATO.

It turns out even the happiest people in the world aren’t that happy. But they are something more like content.

Finns derive satisfaction from leading sustainable lives and perceive financial success as being able to identify and meet basic need

“In other words,” he wrote in an email, “when you know what is enough, you are happy.”

“‘Happiness,’ sometimes it’s a light word and used like it’s only a smile on a face,” Teemu Kiiski, the chief executive of Finnish Design Shop, said. “But I think that this Nordic happiness is something more foundational.”

e conventional wisdom is that it’s easier to be happy in a country like Finland where the government ensures a secure foundation on which to build a fulfilling life and a promising future. But that expectation can also create pressure to live up to the national reputation.

“We are very privileged and we know our privilege,” said Clara Paasimaki, 19, one of Ms. Hansen’s students in Kokkola, “so we are also scared to say that we are discontent with anything, because we know that we have it so much better than other people,” especially in non-Nordic countries.

“The fact that Finland has been ‘the happiest country on earth’ for six years in a row could start building pressure on people,” he wrote in an email. “If we Finns are all so happy, why am I not happy?

The Finnish way of life is summed up in “sisu,” a trait said to be part of the national character. The word roughly translates to “grim determination in the face of hardships,” such as the country’s long winters: Even in adversity, a Finn is expected to persevere, without complaining.

“Back in the day when it wasn’t that easy to survive the winter, people had to struggle, and then it’s kind of been passed along the generations,” said Ms. Paasimaki’s classmate Matias From, 18. “Our parents were this way. Our grandparents were this way. Tough and not worrying about everything. Just living life.”

Since immigrating from Zimbabwe in 1992, Julia Wilson-Hangasmaa, 59, has come to appreciate the freedom Finland affords people to pursue their dreams without worrying about meeting basic needs

When she returns to her home country, she is struck by the “good energy” that comes not from the satisfaction of sisu but from exuberant joy.

“What I miss the most, I realize when I enter Zimbabwe, are the smiles,” she said, among “those people who don’t have much, compared to Western standards, but who are rich in spirit.”

Many of our subjects cited the abundance of nature as crucial to Finnish happiness: Nearly 75 percent of Finland is covered by forest, and all of it is open to everyone thanks to a law known as “jokamiehen oikeudet,” or “everyman’s right,” that entitles people to roam freely throughout any natural areas, on public or privately owned land.

“I enjoy the peace and movement in nature,” said Helina Marjamaa, 66, a former track athlete who represented the country at the 1980 and 1984 Olympic Games. “That’s where I get strength. Birds are singing, snow is melting, and nature is coming to life. It’s just incredibly beautiful.”

“I am worried with this level of ignorance we have toward our own environment,” he said, citing endangered species and climate change. The threat, he said, “still doesn’t seem to shift the political thinking.”

Born 17 years after Finland won independence from Russia, Eeva Valtonen has watched her homeland transform: from the devastation of World War II through years of rebuilding to a nation held up as an exemplar to the world.

“My mother used to say, ‘Remember, the blessing in life is in work, and every work you do, do it well,’” Ms. Valtonen, 88, said. “I think Finnish people have been very much the same way. Everybody did everything together and helped each other.”

Maybe it isn’t that Finns are so much happier than everyone else. Maybe it’s that their expectations for contentment are more reasonable, and if they aren’t met, in the spirit of sisu, they persevere.

“We don’t whine,” Ms. Eerikainen said. “We just do.”

The students who’d been told they were almost always right were, on average, no more discerning than those who had been told they were mostly wrong.

In the second phase of the study, the deception was revealed. The students were told that the real point of the experiment was to gauge their responses to thinking they were right or wrong.

Once again, midway through the study, the students were informed that they’d been misled, and that the information they’d received was entirely fictitious. The students were then asked to describe their own beliefs

The students who’d received the first packet thought that he would avoid it. The students in the second group thought he’d embrace it.

One implication of the naturalness with which we divide cognitive labor,” they write, is that there’s “no sharp boundary between one person’s ideas and knowledge” and “those of other members” of the group

Humans’ biggest advantage over other species is our ability to coöperate. Coöperation is difficult to establish and almost as difficult to sustain

Reason is an adaptation to the hypersocial niche humans have evolved for themselves

Consider what’s become known as “confirmation bias,” the tendency people have to embrace information that supports their beliefs and reject information that contradicts them

Of the many forms of faulty thinking that have been identified, confirmation bias is among the best catalogued; it’s the subject of entire textbooks’ worth of experiments

Even after the evidence “for their beliefs has been totally refuted, people fail to make appropriate revisions in those beliefs,” the researchers noted. In this case, the failure was “particularly impressive,”

reason is an evolved trait, like bipedalism or three-color vision. It emerged on the savannas of Africa, and has to be understood in that context
