Personality differences uncovered between students at different US universities – Research Digestlarger universities tended to have more extraverted students; more urban and diverse universities had more open-minded students; universities requiring letters of recommendation had more agreeable students; public colleges had less agreeable students than private colleges; and more expensive colleges had higher trait Neuroticism. Differences like these could reflect students with particular personality profiles being drawn to particular institutions; selection could be at play, in the sense of university selectors showing a preference for particular personality types; and also students’ personalities could be shaped by the culture of their university.
When Pixels CollideEach pixel you see was placed by hand. Each icon, each flag, each meme created painstakingly by millions of people who had nothing in common except an Internet connection. Somehow, someway, what happened in Reddit over those 72 hours was the birth of Art.
The Utter Uselessness of Job Interviews - The New York TimesIn one experiment, we had student subjects interview other students and then predict their grade point averages for the following semester. The prediction was to be based on the interview, the student’s course schedule and his or her past G.P.A. (We explained that past G.P.A. was historically the best predictor of future grades at their school.) In addition to predicting the G.P.A. of the interviewee, our subjects also predicted the performance of a student they did not meet, based only on that student’s course schedule and past G.P.A. […] In the end, our subjects’ G.P.A. predictions were significantly more accurate for the students they did not meet. The interviews had been counterproductive.
The Utter Uselessness of Job Interviews -People who study personnel psychology have long understood this. In 1979, for example, the Texas Legislature required the University of Texas Medical School at Houston to increase its incoming class size by 50 students late in the season. The additional 50 students that the school admitted had reached the interview phase of the application process but initially, following their interviews, were rejected. A team of researchers later found that these students did just as well as their other classmates in terms of attrition, academic performance, clinical performance (which involves rapport with patients and supervisors) and honors earned. The judgment of the interviewers, in other words, added nothing of relevance to the admissions process.
Under challenge: Girls' confidence level, not math ability hinders path to science degrees -- ScienceDailyThe research team found perception gaps are even wider at the upper levels of mathematics ability -- among those students with the most talent and potential in these fields. Boys are significantly more confident in challenging mathematics contexts than otherwise identically talented girls. Specifically, boys rated their ability 27 percent higher than girls did. Perceived ability under challenge was measured using a nationally representative longitudinal study that followed 10th grade students over a six-year period until two years after high school. A series of questions in the 10th and 12th grade surveys asked students to indicate their level of agreement with statements such as "I'm certain I can understand the most difficult material presented in math texts."
Primary care doctoringOther studies found that people with a primary-care physician as their usual source of care had lower subsequent five-year mortality rates than others, regardless of their initial health. In the United Kingdom, where family physicians are paid to practice in deprived areas, a ten-per-cent increase in the primary-care supply was shown to improve people’s health so much that you could add ten years to everyone’s life and still not match the benefit. Another study examined health-care reforms in Spain that focussed on strengthening primary care in various regions—by, for instance, building more clinics, extending their hours, and paying for home visits. After ten years, mortality fell in the areas where the reforms were made, and it fell more in those areas which received the reforms earlier. Likewise, reforms in California that provided all Medicaid recipients with primary-care physicians resulted in lower hospitalization rates.
IBM is ending its decades-old remote work policy — QuartzTeam proximity appears to help foster better new ideas. One Harvard study found that researchers who worked in close physical proximity produced more impactful papers. Another report used data from badges that collect data on employee interaction to argue that employees who have more chance encounters and unplanned interaction perform better. This idea, known as the “water cooler effect,” has been embraced by the most successful technology companies. Steve Jobs was obsessed with creating unplanned meetings, going so far as to propose building all of the bathrooms in Pixar’s offices in only one part of the building to encourage them (luckily for Pixar employees, someone vetoed this idea). Facebook offers workers a $10,000 bonus if they live near headquarters.
More trust = giving more, expecting kharmaTo measure trust and its reciprocation (trustworthiness) objectively, my team used a strategic decision task developed by researchers in the lab of Vernon Smith, a Nobel laureate in economics. In our experiment, a participant chooses an amount of money to send to a stranger via computer, knowing that the money will triple in amount and understanding that the recipient may or may not share the spoils. Therein lies the conflict: The recipient can either keep all the cash or be trustworthy and share it with the sender. To measure oxytocin levels during the exchange, my colleagues and I developed a protocol to draw blood from people’s arms before and immediately after they made decisions to trust others (if they were senders) or to be trustworthy (if they were receivers). Because we didn’t want to influence their behavior, we didn’t tell participants what the study was about, even though there was no way they could consciously control how much oxytocin they produced. We found that the more money people received (denoting greater trust on the part of senders), the more oxytocin their brains produced. And the amount of oxytocin recipients produced predicted how trustworthy—that is, how likely to share the money—they would be. Since the brain generates messaging chemicals all the time, it was possible we had simply observed random changes in oxytocin. To prove that it causes trust, we safely administered doses of synthetic oxytocin into living human brains (through a nasal spray). Comparing participants who received a real dose with those who received a placebo, we found that giving people 24 IU of synthetic oxytocin more than doubled the amount of money they sent to a stranger.
The Neuroscience of TrustRespondents whose companies were in the top quartile indicated they had 106% more energy and were 76% more engaged at work than respondents whose firms were in the bottom quartile. They also reported being 50% more productive—which is consistent with our objective measures of productivity from studies we have done with employees at work. Trust had a major impact on employee loyalty as well: Compared with employees at low-trust companies, 50% more of those working at high-trust organizations planned to stay with their employer over the next year, and 88% more said they would recommend their company to family and friends as a place to work.
To succeed, plan to fail (occasionally)Do Vale conducted a pair of diet-related experiments. A ‘straight striving group’ was asked to adhere to a strict regimen of 1,500 calories per day with limited food choices, while an ‘intermittent striving’ group was given an even stricter diet of 1,300 calories with limited choices; however, after six days of strict dieting the second group was allowed one day of 2,700 calories with unlimited food choices. Do Vale found that the ‘intermittent’ strivers had higher self-regulatory abilities, while generating a greater variety of strategies to overcome food temptations: they were more motivated to see the diet through. Participants in the ‘straight striving’ group, meanwhile, were more likely to quit the diet and report emotional setbacks when they accidentally overate. It follows that, so long as it is planned, it is often good to be bad. ‘The only way to get rid of temptation,’ Oscar Wilde wrote in The Picture of Dorian Gray, ‘is to yield to it.’
Plan to fail (occasionally)Rita Coelho do Vale is an assistant professor at the Católica Lisbon School of Business and Economics, where she researches the human decision-making process with respect to self-regulation. She says that we not only can but should engage in behaviour antithetical to our ultimate goals. In experiments conducted with Rik Pieters and Marcel Zeelenberg, and published in January 2016 in the Journal of Consumer Psychology, do Vale surveyed the way people go about achieving their goals. She concluded that it is better to make plans to fail intermittently – to splurge on occasional luxuries when saving for a house; to have a slice of chocolate cake when trying to shed a few pounds – than to end up failing anyway and getting so demoralised you give up your goal altogether. ‘It’s something that’s so obvious, but no one has ever studied these phenomena,’ do Vale told me. ‘We all plan for breaks during the day – coffee, a nap – and we know that we will feel better after these rests. But with goals we simply don’t think like this.’
Animals, like humans, place a higher value on what requires more effort.We have examined the justification of effort effect in animals and found a pattern similar to the one in humans but we propose a simpler underlying mechanism: contrast between the greater effort and the resulting reward that follows. The contrast model predicts that any relatively aversive event will result in a preference for a reward (or for the signal of a reward) that follows. Much evidence supports this model: Signals for reward are preferred if they are preceded by having to make a greater number of responses, encountering a longer delay, or experiencing the absence of food (when food is presented on other trials). Contrast has also been found when the signals are associated with greater rather than less food restriction. We have also found a shift toward the preference of a food location that requires greater effort to obtain. Analogous effects have been found in humans (both children and adults) using similar procedures.
How many friends can you have?The Dunbar number is actually a series of them. The best known, a hundred and fifty, is the number of people we call casual friends—the people, say, you’d invite to a large party. (In reality, it’s a range: a hundred at the low end and two hundred for the more social of us.) From there, through qualitative interviews coupled with analysis of experimental and survey data, Dunbar discovered that the number grows and decreases according to a precise formula, roughly a “rule of three.” The next step down, fifty, is the number of people we call close friends—perhaps the people you’d invite to a group dinner. You see them often, but not so much that you consider them to be true intimates. Then there’s the circle of fifteen: the friends that you can turn to for sympathy when you need it, the ones you can confide in about most things. The most intimate Dunbar number, five, is your close support group. These are your best friends (and often family members). On the flipside, groups can extend to five hundred, the acquaintance level, and to fifteen hundred, the absolute limit—the people for whom you can put a name to a face.
All together or all apartThe researchers then had the teams complete a decision-making activity (in this case, act as top management for a fictional Hollywood studio tasked with green-lighting the production of one or more screenplays) and then answer a survey about the experience wherein they rated other team members. "We learned that if you want to have a clear leader emerge, you are better off having them all located face to face or all working remotely," Reeves said. "It's when you start mixing and matching -- some on site, some virtual -- that's when the real confusion comes into play."
Compromise nearly guaranteed when a woman is involved in decision-making pairs: Study finds when making joint decisions, men need to prove masculinity, 'push away' from compromise -- ScienceDaily"The compromise effect basically emerges in any pair when there is a woman. However, surprisingly, when you have men choosing together, they actually tend to push away from the compromise option and select one of the extreme options. Say two men are choosing a car and the cars they are considering differ on safety and fuel efficiency -- they will either go for the safest car or the one that offers them the most fuel efficiency, but they won't choose an option that offers a little of both." In contrast, individuals and mixed-gender and female-female pairs will likely go for the middle option since it seems reasonable and is easily justified.
Pocket: My ListJust be optimistic about the future of your relationship. In a study recently published in the Journal of Personality and Social Psychology, Edward Lemay, a professor of psychology at the University of Maryland, found people who predicted that they would be satisfied with their relationship in the future were more committed to their partners and treated them more kindly in the present-day.
Overall, guests asked to make a specific commitment and who were given a pin were most likely to hang towels for re-use, and they hung a greater proportion of their used towels than guests in the other conditions. These guests were also more likely to turn out the lights when leaving the room than guests in other conditions. Interestingly, those guests given a Friend of the Environment pin who did not get any message were actually less likely to hang towels for re-use than those in other conditions. Advertisement Guests who agreed to the general goal to save energy were at best slightly more likely than those who received no message at all. Thus, the general goal had little impact on people’s behavior. This finding is interesting, because people were somewhat more willing to commit to the general goal than to the specific one.
