(Perhaps this is more Inverse Theory, but I associate the two)
There are three stable, complete moral views: the true one, the inverse of the true one, and the empty one. (If stable is confusing, think logically consistent).
Suppose one chooses a single theory, and holds it sacred; whenever it conflicts with another theory, it considered better. What will happen, in the limit, as this person acquires a complete view of morality? For a few cases like "nothing else is true" or "only 5 things are true", we get a mess. But for most statements, like "my bed is on the floor", the person will approach either the true or inverse view. (Not exactly, there are issues like how s/he will react to moral questions about holding views sacred).
The point is, if one is very very attached to a theory, and it is false, then, the more one bases her or his view around the theory, the more her or his view will approach the inverse view. And thus holding any theory dogmatically is very, very dangerous and wrong.
Bits of this can be observed in the world. Like the way people who deny that my door exists, virtually always hate Jews.
And suppose we do not hold a theory sacred, and do have a predominantly good view. Then, barring misfortune, we should expect our view to generally improve. And if our view is predominently bad, without help, .... I suppose it depends on specifics of how brains and creativity work, but I was going to say to expect it to get worse.
