>Biases are irrational, by definition.

Not all biases are irrational...in fact most biases are in rational predispositions based on knowledge and/or first hand experience. Basically its an attempt to apply logic/rationality to unknown situations.

Bias is always framed as a negative word/trait, and it certainly can be (like racial prejudice), but bias should also be looked at as an evolutionary tool humans can use to apply past learned experiences to similar situations in the future.

Just as an example, motorcycle riders may have a bias against certain types of vehicles because of their training/experience, and they apply this bias when making decisions that impact their safety on the road, even though the specific vehicle/situation may not pose a danger. In an evolutionary context, maybe you saw a fury 4 legged animal kill one of the members of your tribe, so you apply a bias against all 4 legged fury animals. Now you don't know if all fury 4 legged animals are dangerous, or pose a threat, but at the same time its no irrational to apply the bias because in potentially life/death situations it may be better safe than sorry. Obviously its good to keep and open mind, maybe you can train such an animal and it may even turn out to be your best friend, but nothing wrong with approaching the situation with your bias either.

Two types of rationality are being conflated here, namely "close to the truth" and "increases my odds of surviving".
