Data Is Beautiful

lefties are much more likely to commit suicide than righties.

That's interesting (and tragic, obviously).

The idea that it could be an environmental thing (pressure to conform in a right-handed world, the schools and church stuff you mentioned) is quite compelling.

On the other hand, the increased prevalence of genius, and alcoholism, suggests maybe something genetic (or whatever) - like left handedness might go along with certain inherent psychological traits, which might also tend more towards self harming behaviour.

I know nothing about any of this stuff beyond a general interest, so I've no doubt it's a lot more complicated than that (and/or that this is just correlation rather than causation in one direction or another) but it's interesting regardless.
