Hat tip to Upworthy.com for posting a video from 2009 that highlights a story by Neil DeGrasse Tyson that was in response to a question about genetic differences in women possibly accounting for why so few women enter scientific fields. His story about his journey to becoming a scientist illustrates his final point, which is that BEFORE scientists — and the rest of us — talk about genetic differences, we have to come up with a system where there’s equal opportunity.

The Upworthy video doesn’t play. Here’s a YouTube link that should start just before his comments, which begin in answer to a question at 1:01:48.
