Further muddying the waters is sometimes the bias is correct and sometimes it isn't, and the way the terms are used doesn't make it easy to distinguish between those cases and it easily becomes a sticking point for political arguments where people talk past each other.

A bias could be said to be objectively wrong if it leads to suboptimal performance in the real world.

A bias could be objectively correct and improve real-world performance but still be undesirable e.g. leveraging the fact that some demographics are more likely to commit crimes than others. This is a proven fact but if implemented makes the innocent ones amongst those demographics feel like 2nd class citizens and can also lead to domino effects.
