During my recent MBA I came across behavioural economics - and it was a light-bulb moment. It is how, and why, people do/think/react the way they do; part economics, part sociology, part psychiatry, and part sheer magic.
Below is a link to an article on the BehaviouralEconomics.org site on how to take the bias out of recruitment, and like so many BE theories it's blindingly obvious once it's been pointed out. They are looking at how using selective information, or even using 'dummy' applicants, can help in the decision making by negating our natural biases. The authors' research reveals that how recruiters think about and evaluate people is not fixed, it depends on the context in which they're being evaluated - specifically in the context of other people.
