Egalitarian what?

What behavioral issues?

Checking all the evidence you think of checking could be ok or it could be totally inadequate. Really depends, right?

I'm not sure what the bird professor did wrong. Did he ignore evidence he should've paid attention to? If he checked what he was supposed to check, then it seems like he didn't do anything wrong. If it turns out his theory is not true, them's the breaks, right? Such is the fate of man that our theorizing is not foolproof.

Interesting. So "wrong" in context pretty much means "false." Certainly your razor looks quite unwise. The claim that "When I make an assertion, it may seem right in my head, but sometime in the future someone may disprove my assertion" requires some unpacking. Do you mean like for every assertion? There are assertions that are not possibly disproven (in the sense of being proven to be false). I suppose any true assertion is such that it's not possible to prove that it's false. It is true after all. It can't happen that in the future there is some argument out there that makes it seems like it's false. But that's a different thing.

The phrase "possible way the assertion is wrong" seems to suggest a different idea. Perhaps you have in mind different interpretations of a single assertion? On some interpretations the assertion is false, say? There are two things: (a) a more or less clear single assertion and its future vicissitudes vis a vis efforts to prove its falsehood; (b) a vague or ambiguous assertion, its various disambiguations, and various efforts to prove the different interpretations false.
