A hormonal post

There's quite a detailed, balanced and interesting article up at The Guardian: 

Does testosterone make you mean?

The answer seems a definite "it's complicated."

It does note one experiment I don't recall reading about:

Because women are more responsive than men to supplemental testosterone, they were used in one of the key studies into how testosterone essentially removes the burden of empathy from moral decision-making. It’s known as the “trolley car experiment”. Picture a runaway tram hurtling down the tracks towards five unsuspecting workers. There’s a lever that would divert the tram to another track, but there’s someone working on that track, too. “You have to kill somebody to save five others,” says Ryan, and you have to act fast.

The researchers at Utrecht University gave some of the subjects a shot of testosterone the night before presenting them with the dilemma. “The number of respondents who were willing to kill in order to save people, and their confidence in carrying out the act were enhanced,” says Ryan. “And the equivocation they demonstrated was significantly reduced.”

Based on this, I diagnose Chidi in The Good Place as suffering from low testosterone!

(By the way, I've nearly finished Season 2 of that show, and it continues to be a delight.  I see that it has been renewed for a 3rd series, which gives me some concern as to how the creativity of the show can continue to be sustained.)
