When doing scientific work, a lot is being done to assess the biases that could be at play. Knowing them is seen as a way to be able to avoid their impact.
I’m not sure if the perceived problem is the fact that biases most often are unconscious and thus feel out of one’s control, or if the perceived problem is what is seen as a lack of objectivity in the results.
Biases establish a sense of ambiguity. If justice is important to us, biases seem to be in its way. The same is true whenever perfection or doing the right thing is what is important to us.
However, it isn’t the bias that is the problem; it is that those involved may not be aligned as a result of their respective biases. Which, in turn, may prevent people from aligning their opinions, objectives, and perceptions.
While we may appreciate differences, creating alignment is important to many, as it is a way to reduce or avoid conflict and stay in control. The more aligned people are the better the predictability and the less risk of misunderstandings.
However, biases are core elements of our subjectivity. They impact how we perceive the world, and thus our subjectivity. And subjectivity is what we use to adapt ourselves to others. As it is our perception of the situation, others, and ourselves, it is also up to us to change it.
Would we become objective, we’d end up unable to change.
