“[A] genetic variation is linked with the tendency to look on the bright side of life. This is a key mechanism underlying resilience to general life stress. The absence of this protection in the other forms of this genotype is linked with heightened susceptibility to anxiety and depression.”
So says University of Essex professor Elaine Fox, lead author of a paper published Feb. 25 in Proceedings of the Royal Society B, “Looking on the bright side: biased attention and the human serotonin transporter gene.” (HT: Scientific American, May 2009, “Half Empty or Half Full,” Briefs, p. 28.)
I wonder whether people having this genetic predisposition toward optimism are any more inclined to trust that in the end, all will be well.
I’m also curious whether people having such trust are more inclined to believe in the existence of a Creator resembling, at least somewhat, the God of the great monotheistic religions.
