This is very interesting but there is one obvious loose end that would be impossible to tie up. Nobody had any local knowledge about the people who drifted off. My aunt has pages and pages of our family tree compiled. A large fraction of the males in the tree (best guess from memory—I haven’t looked at it in a while—a fourth to a third) went off to work or went off to the army or mysteriously disappeared at a very young age and nobody ever heard a word from them again. So your natured cohert is biased to those who never left home. This is a fundamental human difference and would probably be a useful axis of distinction for a big five type classification scheme. A lot of people never leave home. A lot of people return every Christmas and go to their high school reunion every five years.
And a lot of people just cannot be bothered to do so. A lot. And you will never capture them in your sample if you want to do a study like this. Even that famous 50 year longitudinal Harvard study which is supposedly the greatest trove of social science research we have has missing members due to this.
