I am not sure I’m fully understand about Mind Projection Fallacy, but I answered it with: Yes.
The point is the word “truth” that we, English language, use today is not truth in the sense of everything is true and everyone accept it as true; but only part of it is true, I called in facts, and the rest of the part is just an opinions.
Yes and no, depends on the context. In reality, some of patterns can be taken as practically true and some of it is not.
As an example, If I drop something from top of building, it’s always go down to the ground; this pattern is always reproducible with the same result by all peoples who can test it. But, if I drink hot water when I’m sick and I get healthy in the next morning, that would become biased, because it’s not always reproducible with the same result.
I think, it’s only a matter of how someone defined the value for “well-verified” and “limit” until it become true for himself.
