I can only answer that for my vision. Reason? It is the other sense which I have put to test and failed at seeing the "truth." Have not had the experience with the other senses to know how often I am right. Do you trust your vision 100% Myles? If so, are you immune to these failures triggered by how our vision+brain work?
Based on watching many episodes of "Brain games" TV show above, I have realized that my vision is not to be trusted either.
How much we trust each sense is a function of how often we have found them to be wrong. To know that the answer is "wrong" requires knowing the "truth." The truth is given to us in the above video tests. In our audio lives however, we often or most of the time don't know the truth. When we hear the difference between two wires, what determines if we are right or not? Is it not possible that there is no difference yet we heard it? If so, how did you arrive at the percentage of the time you are right?
I used to think no blind tests were necessary for speakers. Big differences must mean sighted tests work. Then I take the test blind and I realize I was way off. Until that one pivotal moment, I was completely oblivious to that fact. I "trusted" my ears when I should not have. I only knew that after the curtains opened and I realized I would have voted differently with it always that way.
Until such time that you have tested yourself enough times where the "truth" is known and can be compared to your answers, your self-assessment that you should trust your ears is neither here, nor there. You have made up an answer for that. It has no connection to reality of how good your hearing is.
