—“General knowledge, scientific knowledge, and testimonial truth will pretty much reduce any error you might accumulate through normal human cognitive bias. And, from what I can see, the general challenge of improving demonstrated intelligence is not getting smarter, it is making fewer errors.

I know engineers who are not particularly smart, but they demonstrate the intelligence that they do have very well, because engineering-thinking is pretty scientific and practical. I see this in doctors as well as engineers. Whether they’re exceptional or not matters less. Their entire profession is built upon the scientific principle of doing no harm. So they may fewer errors.

Too bad economists and politicians don’t do the same.”—
