We can't inspect human brains, they are black boxes. People are incredibly biased, but also mostly unaware of their biases. For instance, judges have been found to give much harsher sentences just before lunch, when they are hungry. Or attractive people get much shorter sentences. In job interviews attractive people do better. It also matters way more in tipping waitresses and in elections. But on top of that, humans almost always do worse than even the most simple statistical baselines. Simple linear regression on a few relevant variables beats human 'experts' 99% of the time. Humans shouldn't be allowed to make decisions at all, yet everyone seems to fear teh scary algorithms instead.
