Bias is everywhere, but the amount of it varies. In physics, the standard for saying something is "true" is usually a 5(1 in 2 million) or 6(one in 500 million) sigma chance that the fact is not true. In the social sciences, people publish results with a 1 in 20 chance the paper's results are false (and other problems with most social science papers makes the real chance of truth even lower). It is quite useful to have a mindset that is less binary when searching for the truth. I try and calibrate my thinking to "How likely is this to be true" and be constantly updating my view of things with new evidence. Most successful truth seekers I know do the same.
