Social problems of objectivity

This might just be a cultural thing, but to me the idea of objectivity seems like a social taboo... Its just awkward to ever directly talk about it. Probably since it makes ones opinion seem more valuable than others. But objectivity is a real and important thing that can be enhanced through techniques.

For example the peer review in the scientific method does improve objectivity. Simply thinking like: "how could I be wrong?" does on average increase objectivity. For me objectivity should be a normal thing to talk about... it probably should be taught in schools as its own subject with general critical thinking or something... to me its just that important since it is one of the three biggest barriers to get to something close to "truth". Others being analytical skill and knowledge.
