Something people often don't consider is the limited resources for doing science - time, money, etc.

The positive side to "bias" is intuition. This is where a bias ("I'm pretty sure it'll turn out to work like XYZ, so I'll do this experiment next, rather than getting bogged down in some other area.") massively shortcuts the amount of resources required to come to a scientific conclusion.

During my PhD, I made many such shortcuts, following my nose. If I didn't, and tried to do everything objectively, I'd still be optimising buffers, and other such things.
