Conversely, Extroverts can’t get enough Dopamine, and they require Adrenaline for their brains to create it. Extroverts also have a shorter pathway and less blood-flow to the brain.
self-identified introversion is likely to be an excuse for social anxiety and/or laziness in manners and socializing.
nickrussell, I'm sorry I don't have time to go into all of the ways I disagree with your comments in this thread, but I must note my disagreement. You are making some pretty out-there claims without evidence.
It's been half a decade since I last looked at this vein of research and thinking, so apologise if my cleaver is dull and the butchering imprecise.
To show your claim that extraversion co-occurred with "short pathways" you would want to demonstrate that reaction time was correlated with extraversion, which I don't believe anyone has demonstrated (but if you have a cite, I'd be glad to hear it).
The idea that extraverts seek agreement rather than innovation? That ignores findings that extraversion is independent from agreeableness. The closest proxy I have for innovation, Openness to Experience, is also empirically independent from extraversion.
The idea that introverts get more blood to the brain than extraverts is so ridiculous on its face that it requires a cite.
Dopamine is the reward chemical for interacting with the external world. It's provided to reward provision of food, water, sex, and the basic biological needs.
This is incorrect. Dopamine is also released when reward is anticipated, not just acquired. It is also released in relation to the fulfillment or anticipated fulfillment of desires that are not basic biological needs.
The MBTI is not taken seriously in the psychology research community. It is a big hit in business, I suppose. Psychology researchers prefer the Big Five, Cattell's 16PF, Eysenck's three factor model, etc.
I'm aware that it's difficult for more uninformed people to evaluate authoritative-seeming assertions, but a lot of what he's written should set off some alarms. I think it's unfortunate that the comment has been sidebarred, but what are you gonna do? People have to learn to evaluate claims on the internet critically. A good rule-of-thumb, though, is that any simple and yet comprehensive explanation of human personality and behavior is almost certainly BS and someone, somewhere, wants to sell you something on the basis of your acceptance of this explanation. It's true with absurdly ambitious generalizations about introversion/extroversion
variant of extra- (used to contrast with intro-): extrovert.
large chunks of your comment use terms and contain claims that look expert, but do not stand up to the merest scientific scrutiny.
it's good to see a conversation grow out of it.
they are well aware that their audience is pretty much just you, not the zillion people who saw it on the sidebar.
