To the majority of people, every issue has 2 sides. One is right, and the other is wrong. The impression is that, if something is wrong about an argument, a position, a theory, then the entire thing is wrong. This is Aristotelian or Boolean reasoning. Famous smart people use this binary right/wrong or true/false principle to do great things. But…

Once upon a time, the world was flat. We now know (as of at least 2000 years ago) that this is wrong.
Once upon a time, people thought the world was a sphere. In the 19th century, it was measured that this was wrong.

Are these ideas both equally wrong, or is one more wrong than the other? In science, one recognizes degrees of error, magnitudes of mismeasurement. The flat Earth is off by a dimension, whereas the spherical Earth is off by a few percent. (It is fatter around the equator from spin, stretched further by lunar tide, and oddly flattened near the South Pole (possibly related to the events that caused the moon to splash off, and/or the continents to rise)).

Some ideas can be wronger than others.

When Creationists gleefully point out that (popular evolutionist) was in error about (detail of the theory at the time), they use this to claim that the entire structure of the theory is wrong. Never mind that this detail was usually found to be wrong by discovering its replacement in supporting the original theory.
