"It's always too soon to talk about gun control"

[Labster]

I can answer one part of the question from a recent thing I read, on trust.

There were similar differences between countries. Germany (n = 192) at 2.35, the UK (n = 353) at 2.37, and Canada (n = 2.39) were all significantly more trusting than the US (n = 3124) at 2.53 – but obviously the effect wasn’t too impressive. There were only two non-western countries with remotely usable sample sizes. Brazil (n = 28) was 2.89, and India (n = 27) was 2.81. The non-western/Anglosphere difference was significant even with the low sample size. The most trusting city in the world was Toronto (n = 60), at 2.23.

1 = most trusting, 5 = least trusting

It is a self-selected survey, done by a blogger, but at least this blogger is a psychiatrist who knows the subject area.   He's also a rationalist, and well aware of the p-hacking problems -- he's using p = 0.001.
