I don't know if the statistic applies to 95% of economists. It's for the
general American population.

You could take a sample of the students as they entered, then check their
political allegiance again after graduation. We can count those who become
libertarians to check how much of that is rationality and how much is peer
pressure and random drift. Though unfortunately libertarianism is nowhere
near as good an indicator as would be the case in, say, atheism. Maybe
instead we ought to count the students who become atheists and see where
their political allegiance goes.

Again, the statistic is for the general population. As for the notion of
having "better grounds" for the same position you started out with, that,
from a rationalist perspective, is ridiculous. The only possible way to
improve the goodness of your opinion is to change your opinion, unless the
facts themselves have changed.

Agreed.

A paradox? Why do you see a paradox when looking at facts? Your model of
reality must be producing the wrong predictions, if it takes real-world
facts and names them paradoxes.

Paradoxical? Of course not. It strikes me as being more or less what I
would expect, though I do not claim it as my advance prediction.
My conclusion is that it takes both rationality and knowledge; both facts
and the ability to be swayed by facts. The more rational you are, the less
the crushing weight of evidence needed to force you to choose between
finally admitting the obvious to yourself or losing your self-respect.
Science is a method for accumulating such massive evidence that even
scientists cannot ignore it. This is the distinguishing capability of a
scientist; a nonscientist will ignore it anyway.
I aspire to rationality, and not scientism, because I aspire to greater
speed than the social process of science. Not greater long-run power, mind
you, but faster speed. I aspire that it should not take so much evidence
to shake me loose of my delusions as it takes to shift an entire academic
field. Before the social process of science can confirm a hypothesis, some
individual scientist must be rational enough to hypothesize it.
Though I'm not just trying to do better than someone else, of course. I'm
trying to pare down the necessary weight of evidence to the pure Bayesian
minimum, to attain the inertialess mind, to step just as far as I ought to
step and no further on seeing every incoming piece of evidence, to fight
with the forces of fact instead of giving them battle, to willingly follow
trails of evidence wherever they lead, rather than demanding that someone
else shake me loose of my preferred opinion.
I have yet to read such poetry from macroeconomists, nor those other
average scientists from whom you expect such great feats of rationality.
They might agree with the poetry if asked, but they have not said it
spontaneously, nor practiced the art.
