You probably don't know as much as you think you do. When put to the test, most people find they can't explain the workings of everyday things they think they understand.

Find an object you use daily (a zipper, a toilet, a stereo speaker) and try to describe the particulars of how it works. You're likely to discover unexpected gaps in your knowledge. In psychology, we call this cognitive barrier the illusion of explanatory depth. It means you think you fully understand something that you actually don't.

We see this every day in buzz words. Though we often use these words, their meanings are usually unclear. They mask gaps in our knowledge, serving as placeholders that gloss concepts we don't fully understand.

Younger Democratic women are mostly for Bernie Sanders; older women lean more toward Hillary Clinton.

The idealistic but ungrateful naïfs who think sexism is a thing of the past and believe, as Mr. Sanders recently said, that “people should not be voting for candidates based on their gender” are seemingly battling the pantsuited old scolds prattling on about feminism

More time in a sexist world, and particularly in the workplace, radicalizes women.

It is generally well-reported that there is a life expectancy gap between white and black Americans of about four years. But it can be hard to visualize exactly what this number means. In a recent conversation, David Williams, public health researcher at Harvard, described the racial gap to me in stark terms: One of the ways to think of the racial gap in health is to think of how many black people die prematurely every year who wouldn't die if there were no racial differences in health. The answer to that from a carefully done [2001] scientific study is 96,800 black people die prematurely every year. Divide it by 365 [days], that's 265 people dying prematurely every day. Imagine a jumbo jet — with 265 passengers and crew — crashing at Reagan Washington Airport today, and the same thing happening tomorrow and every day next week and every day next month. That's what we're talking about when we say there are racial disparities in health.

I asked Williams why there is such a tremendous gap in black and white life expectancy. He said there's no single issue to blame; it instead comes down to many factors, largely related to where people live.

WHEN measured in terms of academic achievement, Asian Americans are a successful bunch. Forty-nine percent have a bachelor's degree or higher. This compares favourably against white Americans (30%), African-Americans (19%) and Latinos (13%).

Amy Chua, a self-declared "tiger mother" who became famous for promoting the benefits of harsh parenting, would put this down to culture. She has argued that Chinese-American children statistically out-perform their peers because they are pushed harder at home.

she ascribes the success of different cultures in America to a "triple package" comprised of a superiority complex, insecurity and good impulse control. In other words, certain groups tell themselves they are better than other groups, but learn that they have to work hard to succeed, and must resist temptation and distraction in proving themselves.

Students who are wealthier and male are more likely than others to claim that they know more than they actually do, says a new study.

The study, which reviewed surveys of 40,000 15-year-old students from across nine English-speaking countries, found that boys and people from wealthier families are more likely to be “bullshitters,” which it defines as “individuals who claim knowledge or expertise in an area where they actually have little experience at all.”

“You’re claiming expertise in things you have absolutely no knowledge of,” says Shure. “You couldn’t. These things don’t exist.”

“Early life conditions and how children are stimulated play a very important role,” he said. “The danger is we will revert back to the mindset of the war on poverty, when poverty was just a matter of income, and giving families more would improve the prospects of their children. If people conclude that, it’s a mistake.”

hat affluent children spend 1,300 more hours than low-income children before age 6 in places other than their homes, their day care centers, or schools (anywhere from museums to shopping malls). By the time high-income children start school, they have spent about 400 hours more than poor children in literacy activities, she found.

There are no easy answers, in part because the problem is so complex, said Douglas J. Besharov, a fellow at the Atlantic Council. Blaming the problem on the richest of the rich ignores an equally important driver, he said: two-earner household wealth, which has lifted the upper middle class ever further from less educated Americans, who tend to be single parents.

Given that human cognition is never the product of pure dispassionate reason, but a subjective interpretation of the facts based on our feelings and biases and instincts, when can we ever say that we know who is right and who is wrong, about anything? When can we declare a fact so established that it’s fair to say, without being called arrogant, that those who deny this truth don’t just disagree…that they’re just plain wrong

This isn’t about matters of faith, or questions of ultimately unknowable things which by definition can not be established by fact. This is a question about what is knowable, and provable by careful objective scientific inquiry, a process which includes challenging skepticism rigorously applied precisely to establish what, beyond any reasonable doubt, is in fact true. The way evolution has been established

With enough careful investigation and scrupulously challenged evidence, we can establish knowable truths that are not just the product of our subjective motivated reasoning. We can apply our powers of reason and our ability to objectively analyze the facts and get beyond the point where what we 'know' is just an interpretation of the evidence through the subconscious filters of who we trust and our biases and instincts. We can get to the point where if someone wants to continue believe that the sun revolves around the earth, or that vaccines cause autism, or that evolution is a deceit, it is no longer arrogant - though it may still be provocative - to call those people wrong.

Turning a blind eye. Giving someone the cold shoulder. Looking down on people. Seeing right through them. These metaphors for condescending or dismissive behavior are more than just descriptive. They suggest, to a surprisingly accurate extent, the social distance between those with greater power and those with less

A growing body of recent research shows that people with the most social power pay scant attention to those with little such power. This tuning out has been observed, for instance, with strangers in a mere five-minute get-acquainted session, where the more powerful person shows fewer signals of paying attention, like nodding or laughing. Higher-status people are also more likely to express disregard, through facial expressions, and are more likely to take over the conversation and interrupt or look past the other speaker.

A prerequisite to empathy is simply paying attention to the person in pain. In 2008, social psychologists from the University of Amsterdam and the University of California, Berkeley, studied pairs of strangers telling one another about difficulties they had been through, like a divorce or death of a loved one. The researchers found that the differential expressed itself in the playing down of suffering. The more powerful were less compassionate toward the hardships described by the less powerful.

most people don’t want to read and, therefore, don’t read. The evidence on this score is clear: the average American reads for about fifteen minutes a day and almost never reads a book for pleasure.

we have tried to solve the reading “problem” by removing the most obvious impediments to reading: we taught everyone to read; we printed millions upon millions of books; and we made those books practically free in libraries. And so the barriers fell: now nearly everyone in the developed world is literate, there is plenty to read, and reading material is dirt cheap. But still people don’t read. Why? The obvious answer—though one that is difficult for us to admit—is that most people don’t like to read.

Humans achieved their modern form about 180,000 years ago; for 175,000 of those years they never wrote or read anything. About 40,000 years ago, humans began to make symbols,

A Bachelor’s degree taught me how to learn to ace exams. But it didn’t teach me how to learn to remember.

65% to 80% of students answered “no” to the question “Do you study the way you do because somebody taught you to study that way?”

the most-popular Coursera course of all time: Dr. Barabara Oakley’s free course on “Learning how to Learn.” So did I. And while this course taught me about chunking, recalling, and interleaving

After months away from school, some of his classmates seemed to have mysteriously advanced, easily reciting concepts he says they were never taught.

Scott believes other kids in her son’s class spent the spring and summer getting extra tutoring and virtual enrichment, overseen by their parents.

Education researchers have been studying how much learning loss is taking place as a result of school shutdowns and remote school.

Citigroup is making progress toward shrinking its gender pay gap. But it still has some work to do.

Globally, the bank's female employees earned 27% less than men did, according to a new report from the company. That's a slight improvement over the 29% gender pay gap Citigroup reported for 2018. This year's analysis also found that the median income for minority workers in the US was 6% less than the median income for non-minorities, down from 7% last year.

When adjusted to account for job titles, seniority and location, women at Citigroup (C) earned 1% less than their male counterparts, according to the report. Citigroup said that following a review of its global pay, it made pay adjustments as part of this year's compensation cycle according to the blog post.The company also said it has committed to increasing representation at the assistant vice president through managing director levels to at least 40% for women globally and 8% for black employees in the US by the end of 2021.

The Health Care Data Sharing Survey, commissioned and published by Chicago-based clinical data management company Q-Centrix, was conducted in December 2021 with a sample size of 1,191 people.

Fifty-three percent of respondents were female, and 47 percent were male. Respondents fell into four age groups: 18-29 (21 percent), 30-44 (27 percent), 45-60 (29 percent), and over 60 (23 percent). Respondents were also split based on household income: $49,999 or less (41 percent), $50,000-$99,999 (34 percent), and $100,000 or more (25 percent).

These patient concerns may translate to a hesitancy to share data for purposes other than improving their own healthcare. Some respondents said they were unsure about whether they’d be willing to share their de-identified healthcare data for clinical research (21 percent), to improve hospital services (22 percent), to improve other patients’ healthcare (22 percent), and to advance care equity and identify disparities (24 percent).

the gap at the elite schools could be as elemental as their perception as havens for science, technology, engineering or math, making them a natural magnet for boys, just as girls might gravitate to schools known for humanities.

Mr. Finn, who, with Jessica A. Hockett, wrote the recent book, “Exam Schools: Inside America’s Most Selective Public High Schools.” “I think you’re looking at habit, culture, perceptions, tradition and curricular emphasis.”

enrollment in highly competitive high schools is 55 percent female. “The big gender-related chasm in American education these days is how much worse boys are doing, than girls,”

There is good and bad news for climate scientists. The good news: Most Americans (79 percent) say that science and scientists are invaluable

a significant number of Americans do not use science to inform their views. Instead, they use political orientation and ideology, which are reflected in their level of education, to decide whether humans are driving planetary warming.

the vast majority (87 percent) of scientists said that human activity is driving global warming, and yet only half the American public ascribed to that view. And 77 percent of scientists said climate change is a very serious problem. In comparison, only 33 percent of the general public said it was a very serious problem in a 2013 poll.

the Pew Research Center for the People & the Press, which routinely asks voters about the news they are hearing about the economy. In August of 2011, Americans of all parties said the news was mostly bad, with only minor differences showing between members of different political parties.A year later, a survey taken in early September found a "record partisan gap." A full 60% of Republicans said they were hearing “mostly bad” news. Only 15% of Democrats reported the same. And independent voters split on the question, with 36% saying they were hearing mostly bad news

Gallup’s tracking of Americans’ reported confidence in the economy has also seen a dramatic divergence: Democrats’ confidence reached a new high in a survey released September 25; Republicans’ reached a record low.

“Cues and signaling from the political leaders definitely influence how people experience their own lives,”

What happens when children reach puberty earlier and adulthood later? The answer is: a good deal of teenage weirdness. Fortunately, developmental psychologists and neuroscientists are starting to explain the foundations of that weirdness.

The crucial new idea is that there are two different neural and psychological systems that interact to turn children into adults. Over the past two centuries, and even more over the past generation, the developmental timing of these two systems has changed. That, in turn, has profoundly changed adolescence and produced new kinds of adolescent woe. The big question for anyone who deals with young people today is how we can go about bringing these cogs of the teenage mind into sync once again

The first of these systems has to do with emotion and motivation. It is very closely linked to the biological and chemical changes of puberty and involves the areas of the brain that respond to rewards. This is the system that turns placid 10-year-olds into restless, exuberant, emotionally intense teenagers, desperate to attain every goal, fulfill every desire and experience every sensation. Later, it turns them back into relatively placid adults.

Lately inequality has re-entered the national conversation. Occupy Wall Street gave the issue visibility, while the Congressional Budget Office supplied hard data on the widening income gap. And the myth of a classless society has been exposed: Among rich countries, America stands out as the place where economic and social status is most likely to be inherited.

some indicators of social dysfunction have improved dramatically even as traditional families continue to lose ground. As far as I can tell, Mr. Murray never mentions either the plunge in teenage pregnancies among all racial groups since 1990 or the 60 percent decline in violent crime since the mid-90s. Could it be that traditional families aren’t as crucial to social cohesion as advertised?

To be fair, the new book at the heart of the conservative pushback, Charles Murray’s “Coming Apart: The State of White America, 1960-2010,” does highlight some striking trends. Among white Americans with a high school education or less, marriage rates and male labor force participation are down, while births out of wedlock are up. Clearly, white working-class society has changed in ways that don’t sound good.

Much of the early research on motion perception was performed on insects,1 but similar results have been found for a huge range of species, from fishes to birds to mammals

Correspondingly, prey animals would find color vision of little use, but they are extremely good at seeing the motion of an approaching predator.

Ambiguous illusions that can be interpreted in two different ways, but not both ways at the same time, can also shed light on how we perceive the world around us

Mr. Price surprised his 120-person staff by announcing that he planned over the next three years to raise the salary of even the lowest-paid clerk, customer service representative and salesman to a minimum of $70,000.

Mr. Price, who started the Seattle-based credit-card payment processing firm in 2004 at the age of 19, said he would pay for the wage increases by cutting his own salary from nearly $1 million to $70,000 and using 75 to 80 percent of the company’s anticipated $2.2 million in profit this year.

his unusual proposal does speak to an economic issue that has captured national attention: The disparity between the soaring pay of chief executives and that of their employees.
