> People often talk about "bias" as if it's something that obviously ought to be eliminated Yeah, bias means our model of reality is distorted; one doesn't correspond to the other as well as it could. An example of bias, from https://en.wikipedia.org/wiki/Space_Shuttle_Challenger_disaster#Richard_Feynman https://en.wikipedia.org/wiki/Space_Shuttle_Challenger_disas... (appropriately enough) <<<In the appendix, he argued that the estimates of reliability offered by NASA management were wildly unrealistic, differing as much as a thousandfold from the estimates of working engineers. "For a successful technology," he concluded, "reality must take precedence over public relations, for nature cannot be fooled." >>> That is bias, and it killed people and didn't do the US any favours. If by bias you mean something else, your post needed to be clearer.
