One of the enduring strengths of Manager Tools is it's focus on behaviourally-evidenced evaluations. They're all about looking at what people actually do, learning to identify that behaviour, and using it to form evaluations (and vice versa, in order to help people to come off better in evaluations). They're all about practical guidance based on observing real patterns of behaviour. Now, it's one thing thing to talk about anti-discriminatory policies and to just will yourself into being fair. But as Horstman points out in these podcasts, we're all biased in many ways we can't overcome by sheer willpower, in the moment. The only way to defeat one's biases is giving voice to one's judgements - and the only fair judgements you could look someone in the eye and repeat are those based in evidence. I just love this. I was listening to the Manager Tools podcast on how to feed back to job candidates you've rejected after interviewing. He's very impassioned about this and I love this (and how he very obviously uses women in hypothetical examples or will say "her" when talking about hypothetical managers). He goes off about how effective management, guided by principles of observation regarding demonstrated behaviours... He'll go on about how this is the way to fight discrimination in hiring, in firing, in the workplace overall. I mean, it's not a cure-all, but damn if it doesn't go a long way towards routing out the weasley racism or sexism of "she's just not a good fit" or "he's just not quite right."
