Amazon's gender-biased algorithm is not alone by Cathy O'Neil via @infomgmt

Internet giant Amazon recently ran into a problem that eloquently illustrates the pitfalls of big data: It tried to automate hiring with a machine learning algorithm, but upon testing it realised that it merely perpetuated the tech industry’s bias against women

I agree with Cathy here - Amazon should be congratulated for a) testing it properly and b) doing something about it when it was clear there was a problem. It cannot be acceptable to just use the excuse (for that is what it actually is) that you didn't know so cannot be liable. It really makes me mad when we all know that bias is a risk and we should all do the due diligence to test properly to make sure that we ensure it is no longer there. Please recognise bias as a risk and test carefully for it by using someone who is not on your team so they have fresh eyes.
