"I was saying that the one in the creation of man may be deliberate and was trying to show that he had the knowledge, talent, and motive."
Actually, all your efforts were limited to showing he had motive. You didn't dig up any info to prove he had actually dissected heads and seen brains. In other words, you completely neglected the "knowledge" part of your alleged efforts. In addition, falsly alluding to some proof you made of his talent is just plain insidious padding. His talent is not in question by anyone, and isn't something you had to exert yourself to prove.
"I think I've found everything I will be able to find to support my opinion."
Why do you even have this opinion in the first place? I think it has far less to do with Michelangelo than with your affection for the idea that someone might use a subtle device like this in their art. It is such a very neat idea that you are bending over backward to try to substantiate it, however indirectly.
I wish you wouldn't waste your time, because you'll miss what Michelangelo is really about, and that will be gleaned primarily from looking at his work, not reading about what other people have seen in it. If you like secret messages and hyper-symbolism in art, you really should be looking at the graphic art of Albrecht Durer, or the paintings of Hieronymous Bosch. Those are frankly packed with that sort of stuff.
In the meantime:
confirmation bias
From The Skeptic's Dictionary:
Confirmation bias refers to a type of selective thinking whereby one tends to notice and to look for what confirms one's beliefs, and to ignore, not look for, or undervalue the relevance of what contradicts one's beliefs. For example, if you believe that during a full moon there is an increase in admissions to the emergency room where you work, you will take notice of admissions during a full moon, but be inattentive to the moon when admissions occur during other nights of the month. A tendency to do this over time unjustifiably strengthens your belief in the relationship between the full moon and accidents and other lunar effects.
This tendency to give more attention and weight to data that support our beliefs than we do to contrary data is especially pernicious when our beliefs are little more than prejudices. If our beliefs are firmly established upon solid evidence and valid confirmatory experiments, the tendency to give more attention and weight to data that fit with our beliefs should not lead us astray as a rule. Of course, if we become blinded to evidence truly refuting a favored hypothesis, we have crossed the line from reasonableness to closed-mindedness."
"Individuals have to constantly remind themselves of this tendency and actively seek out data contrary to their beliefs. Since this is unnatural, it appears that the ordinary person is doomed to bias."
