Personality Traits Are Linked To Differences In Brain Structure, Says Researchers (neurosciencenews.com)
New submitter baalcat quotes a report from Neuroscience News: Our personality may be shaped by how our brain works, but in fact the shape of our brain can itself provide surprising clues about how we behave -- and our risk of developing mental health disorders -- suggests a study published today. According to psychologists, the extraordinary variety of human personality can be broken down into the so-called 'Big Five' personality traits, namely neuroticism (how moody a person is), extraversion (how enthusiastic a person is), openness (how open-minded a person is), agreeableness (a measure of altruism), and conscientiousness (a measure of self-control). In a study published today in the journal Social Cognitive and Affective Neuroscience, an international team of researchers from the UK, US, and Italy have analyzed a brain imaging dataset from over 500 individuals that has been made publicly available by the Human Connectome Project, a major US initiative funded by the National Institutes of Health. In particular, the researchers looked at differences in the brain cortical anatomy (the structure of the outer layer of the brain) as indexed by three measures -- the thickness, area, and amount of folding in the cortex -- and how these measures related to the Big Five personality traits. The study has been published in the journal Social Cognitive and Affective Neuroscience.
I don't think that extraversion is usually defined as "how enthusiastic a person is". On the contrary, Wikipedia defines it thus:
"Extraversion is the state of primarily obtaining gratification from outside oneself.[4] Extraverts tend to enjoy human interactions and to be enthusiastic, talkative, assertive, and gregarious. Extraverts are energized and thrive off being around other people. They take pleasure in activities that involve large social gatherings, such as parties, community activities, public demonstrations, and business or political groups. They also tend to work well in groups.[5] An extraverted person is likely to enjoy time spent with people and find less reward in time spent alone. They tend to be energized when around other people, and they are more prone to boredom when they are by themselves". https://en.wikipedia.org/wiki/...
I imagine that Slashdotters, on average, have a much higher tendency to be introverted. It's not that extraverts can't be good at technical work - one could cite many examples to the contrary - just that it's easier to put a lot of time and effort into thinking if you don't have a lot of social commitments as well. But surely no one could claim that introverts necessarily lack enthusiasm. It just manifests in different ways.
I am sure that there are many other solipsists out there.
seems like standard brain science statistics - a huge vector of possible brain features/locations crossed with a huge vector of hypothesized behaviors and, surprise surprise, some of the entries in the matrix are "significant." Better get a big publication - tenure review is coming up.
Yes and no. At this point in history, approximately zero of our fighting has anything to do with keeping American citizens physically safe. America has created a kind of empire. And while it is a much kinder and civilized empire than those that came before, it is still vulnerable to the classic blunders of the old style empire, e.g. the Vietnam War.
There is a Chinese saying: "To love war will ruin the nation; to forget warfare endangers everyone."
IMHO, America suffers for loving war far too much, at this point in history.
People who love war are often quick to accuse any other opinion as advocating a complete forgetting of warfare. Of course, that is just the Black-Or-White fallacy. Arguing for less war in the context of the America of today, does not mean arguing for zero wars or zero warfare.
