In 2005, at a conference at the National Academy of Sciences, Tyson responded to a question about whether genetic differences might keep women from working as scientists. He said that his goal to become an astrophysicist was "hands down the path of most resistance through the forces... of society... My life experience tells me, when you don't find blacks in the sciences, when you don't find women in the sciences, I know these forces are real and I had to survive them in order to get where I am today. So before we start talking about genetic differences, you gotta come up with a system where there's equal opportunity. Then we can start having that conversation."
