I think this disagreement comes down to the definition of “bias”, which Wikipedia defines as “a tendency or preference towards a particular perspective, ideology or result, when the tendency interferes with the ability to be impartial, unprejudiced, or objective.” If a bias helps you make fewer errors, I would argue it’s not a bias.
Maybe it is clearer if we speak of behaviors rather than biases. A given behavior (e.g. tendency to perceive what you were expecting to perceive) may make you more biased in certain contexts, and more rational in others. It might be advantageous to keep this behavior if it helps you more than it hurts you, but to the extent that you can identify the situations where the behavior causes errors, you should try to correct it.

Great audio clip, BTW.
