Looking on the bright side of life is in the genes, claim scientists - Telegraph
Dunno, just thought this was kinda interesting. It seems that our outlook on life is affected by genetics.
OK, I don't know much about reinin dichotomies, but taking the description from here, Positivist and negativist - Wikisocion
Would imply that a positive outlook on life is type related, ie glass half full half empty, socially trusting of people vs mistrusting of others, so it's sort of related to being optimistic about things or not.Positivists
More inclined to optimize already functional systems of things and processes.
"This glass is half-full", "We have already collected $438,000 for that project"
Usually more complimenting than reprimanding.
Socially and intellectually more trusting. Explains what things are (irrationals) or should be (rationals).
More inclined to solve problems in systems of things and processes.
"This glass is half-empty", "We need $62,000 for that project"
Usually more reprimanding than complimenting.
Socially and intellectually more mistrusting.
Explains what things are not (irrationals) or should not be (rationals).
In my opinion, people can be of the same type and be optimistic or not.
So, could be that the reinin dichotomy isn't explained properly, or are types just naturally optimistic or not?
Either way, type or otherwise, I think it's interesting if there are any pessimists out there...apparently an optimistic people have better mental health!
