Diversity in math skills vs diversity in IT

I am convinced that all kinds of diversity, helps teams to better achieve what they have to achieve.
I blogged earlier about diversity in Agile
this slideshow (that I picked up from a Brad Felt blogpost, explains why some of the general idea’s is wrong about math and IT.

This makes me think about a part of the book blink, the chapter where Malcom talks about the IAT tests on how we link black and white people to good and bad. A student that took that test daily all of a sudden had a different score (which was a very unusuall), it turned out he had looked at the olympics before the test. If we are surrounded by examples, our brain sees the world different; Now that is why I work on the diversity in agile project.
