Absolutely. I generalized from one datum once, and hoooo boy. I'll never do that again.

I'm being funny, but with a purpose: if acting on one datum was always fallacious, you'd think it would be bred out of us by now. Sometimes you have to act on what you know, and different ages favor different personality types.

For instance, I believe that strong visual people have an advantage in our times. I suspect it's because visual people are able to explore (by quite literally visualizing) much larger solution spaces in shorter periods of time. Like the author I am skeptical of Galton's claim that people who cannot visualize are over-represented in math and science.
