Defining rational as “everything I already think”

Another mistake I’ve noticed in this game of I Am More Rational Than You is judging the officially correct degree of emotionality to be…oh what a coincidence: it turns out to be the degree one has oneself.

You know? As in, “I am very rational, as any fule kno, and I am not very emotional except that I get irritable a lot. Obviously that is the right amount and quality of emotion to have. Any other amount and quality is mistaken and to be reprobated.”

Well it’s a natural mistake to make. We all see things through our own eyeballs and not anyone else’s. But…at the same time, it’s part of rationality to be aware of that tendency and to try to correct for it, along with all the other solipsistic tendencies we naturally have.

Seven of Mine made a related point on PZ’s post:

they’re just assuming their argument is sound because they’re unconsciously defining rational as “everything I already think” and irrational as “everything else.”

Exactly. That kind of thing. Correct for that, or you’ll find yourself in the weeds.
