In a study that tested how impulsivity and the quality of neighborhoods are related to delinquent behavior, researchers found that impulsivity predicted delinquency as expected, but only for boys who lived in poor neighborhoods. In other words, being in a poor neighborhood was related to higher delinquency only for boys who were already impulsive; nonimpulsive boys in poor neighborhoods were no more likely to be juvenile offenders
When researchers have studied the personalities of dogs and of chimpanzees, they find the same big five traits, plus a sixth trait that reflects how dominant they are.
About 40% of the variability that we see in how achievement- oriented different people are has some sort of genetic basis.
One experimental study measured people’s happiness and then injected them with the cold virus. The results showed that happier people were less likely to come down with a cold. And if they did get sick, happier people tended to have less severe symptoms and were sick for fewer days than unhappy people.
Somewhere between 30% and 50% of the variability in happiness across people is due to people’s personality characteristics rather than to the objective quality of their lives.
Research shows that there’s no relationship between affect intensity and happiness overall—probably because happiness reflects the proportion of positive and negative emotions that a person experiences over time. Happy people experience a higher ratio of positive to negative emotions than unhappy people do.
30% to 40% of the variability that we observe in virtuous feelings and ethical behaviors is related to stable aspects of personality
People who identify as liberal versus conservative tend to use the 5 moral foundations differently. In every country that’s been studied, liberals primarily use only 2 of the foundations when they make moral judgments: the one that emphasizes caring for other people and avoiding harm and the one that involves the importance of fairness. Conservatives, on the other hand, tend to endorse and use all 5 foundations—not only care and fairness, but also group loyalty, respect for authority and tradition, and physical and spiritual purity. So, people on the right sometimes judge things as wrong that people on the left don’t even see as moral issues.
Research shows that religious people and conservatives are no more intellectually arrogant on average than atheists and liberals are.
People who think that the world is just are more likely to derogate and blame people for their personal misfortunes. For example, people who score higher in the belief in a just world are more likely to think that poor people are responsible for their plight and that victims of crimes probably did something to cause it or at least weren’t careful enough.
People who score higher in authoritarianism tend to populate the most fundamentalist segments of every religion.
Research has shown that people with different identity orientations give different reasons for being physically active. Having a predominately personal identity orientation is associated with reasons such as improving one’s health and physical condition, feeling better physically, and self-satisfaction. But people with a predominant social identity orientation said they exercised to interact with other people and to look better.
The ability to infer other people’s emotions is more highly heritable than the ability to infer what other people are thinking.
Women are, on average, 2.3 years younger than their male partner.(in USA)
Studies of men who are in prison show that prisoners with higher testosterone are more likely to have been incarcerated for violent crimes, such as murder and assault, whereas those with lower levels of testosterone are likely to be in prison for nonviolent crimes.
Amounts of heritability:• 40% to 60%—Five basic dimensions of personalityThe most individualist countries tend to be the most Westernized; the United States, Australia, Canada, Great Britain, and the Netherlands top the list.
• 50%—Intelligence
• 87%—height
• 43%—identifying as politically liberal or conservative
• 45%—attitude toward organized religion
• 36%—attitudes about exercise
• 37%—attitude toward reading
It’s common for people from Western cultures to assume that the most collectivist cultures are countries in East Asia, such as Japan, but in fact, the most collectivist countries are places such as Ecuador, Peru, Columbia, and Venezuela. Pakistan is also on that list.
Japan actually falls in the middle of the individualist- collectivist continuum, along with countries such as Spain, India, Israel, and Austria. They’re the most balanced between individualism and collectivism.
One study found that self-control was the only personality variable among 32 variables studied that significantly predicted grade point average among college students.
The lecturer told listeners not to become worried if they occasionally manifest symptoms of a "personality Disorder." Estimates are that, in any given year, around 10% of adults would qualify for a diagnosis of at least one of the 10 personality disorders. And many more people would show the general disordered pattern of behavior, but it wouldn’t create enough of a problem for their lives for it to meet the diagnostic criteria. The symptoms need to be sufficiently persistent to damage social relationships to meet diagnostic criteria.
A study conducted in 2015 showed that narcissistic people tend to have parents who overvalued them—who thought they were unusually special— which implies that children seem to acquire narcissism, at least in part, by internalizing their parents’ inflated views of them.
The study also showed that parental warmth, not parental overvaluation, seemed to lead to greater self-esteem in the child, supporting the idea that narcissism is different than just having high self-esteem.
Obsessive-compulsive personality disorder is one of the most prevalent personality disorders in the United States, with an estimated prevalence of about 2.4% of the general population.
Personality disorders appear to be more heritable than most normal personality characteristics. About 50% to 80% of the variability that we see in these disorders seems to be genetic.
Five Criteria of Psychological Adjustment1. a lack of genuine psychopathology or mental illnessA meta-analysis of more than 100 studies showed that flexibility was related to psychological adjustment, well-being, and mental health.
2. the ability to get along with other people and maintain some supportive close relationships
3. the ability to pursue and achieve one’s goals
4. the ability to cope with problems that arise in life
5. a sense of subjective well-being.
Well-Adjusted Personality Types—studies repeatedly reveal 3 qualitatively different types of people, and these 3 basic types of people differ mostly in terms of their psychological adjustment. (1) resilient type, (2) overcontrolled personality type, (3) undercontrolled personality.
Addressing psychological adjustment by classifying everybody into one of 3 personality types is an oversimplification that misses nuances and differences among people within each of these types. But it does reveal a few things about personality and adjustment:— 1. In general, there is only one basic way to be well adjusted but 2 basic ways in which to be poorly adjusted. Fundamentally, the difference between being well adjusted and poorly adjusted lies in how high people are in neuroticism and how well they get along with other people.Extreme childhood trauma can affect well-being, but as long as parents or other adults provide the needed emotional support and rational guidance, a certain amount of stress, struggle, and adversity in childhood actually promotes better long-term adjustment than if the child has no negative experiences.
— 2. The specific characteristics that create the resilient, overcontrolled, and undercontrolled personality types are correlated in nonrandom ways that produce these patterns. In other words, the various characteristics that create each of these 3 types of people tend to go together. People who have one of the characteristics in a profile also tend to have the others.
—3. As we deal with problems in ourselves and in other people,it may be helpful to think about the degree to which those problems reflect the overcontrolled profile versus the undercontrolled profile. Looking beneath the behavioral and emotional manifestations of adjustment problems allows us to think about the psychological characteristics and processes that undermine adjustment and lower well-being in any particular case.
