I am so frenzied, oh yes. Look at me be frenzied. Watch me frenzificating here.
Actually, when I looked at the brief write-up on that news site, I was immediately struck by how dubous the study described was - specifically, the one based on the behavior of drivers. The dramatically poor don’t have cars.* In fact in this day and economy to be able to afford to fuel and maintain a car establishes you as being, not well off, but at least possessing of some source of income. And if you have an income, there is an entire social class of people poorer than you.
In other words, I perceive a probability of sampling flaws. There is a class of people who are under great social pressure to break a window pane to steal a loaf of bread - and I doubt that all of them give the proceeds to their sister’s son, either. And I didn’t get the vibe that these people were represented in the study.
That suspected problem with the study aside, though, it’s still would be very unsurprising to find scientific verification that the very rich skew selfish. Not because being rich makes you selfish, but because being selfish can be helpful in making you rich.
*defined as “people too poor to afford cars”.
