ITT I ask libfags questions

1) Is it wrong to discriminate against certain groups, on the sole basis of skin colour (and not race), by cognitive ability? Please explain why your position position is backed by science. Refrain from answering unless you have a minimal understanding of statistics, please.

Moar questions to follow later, because I feel I'm going to have to deal with a lot of morons with this simple one.

Why would I do that, when almost no one wants to answer a simple question? And related, do you know of any place where can I upload PDFs so that I can link them directly, after/if more libfags answer?
