I think it's far more important that we understand that we are not unbiased. That what we already believe to be real and true IS A BIAS. And is almost certainly an inaccurate bias, given that we are constantly having to struggle to change and correct it over time. Our greatest fault as humans is that we cannot distinguish between what we believe is real and true, from what is actually real or true. Because we have so little actual experience or knowledge of what is real and true. All human history is an ongoing struggle to overcome our ignorance and bias because ignorance and bias is our natural state.
But all any of you arrive at, or even seek, is a solution that "works". Just because something works doesn't mean we understand how or why it works, or that it's a "truth". All it means is that it works the way we expect it to, to the degree that we expect it to.
In mathematics we say that 2 + 2 = 4. But in truth no anythings are absolutely equal to anything else, or they would be the SAME THING. So the most fundamental ideal in mathematics, equality, only exists as a bias in our minds. It cannot logically exist in reality. Yet mathematics 'works' for us because we simply ignore all the ways that it doesn't. Two of these plus two of those "equals" four of them because we just ignore all the ways in which the things we are applying the mathematical equation to are not equal. Thus 2 + 2 = 4 'works', but there is no truth in it beyond that. It's a ignorance, and a bias that, when maintained, remains functional from our perspective.
All truth from a human perspective is gained by fooling ourselves into believing that we know what it is. And once we have successfully fooled ourselves into believing this, we become closed to the idea of an alternative. We become biased by our own presumed "truths".
