Superforecasting: The Art and Science of Prediction

by Philip E. Tetlock

Now look at how foxes approach forecasting. They deploy not one analytical idea but many and seek out information not from one source but many. Then they synthesize it all into a single conclusion. In a word, they aggregate. They may be individuals working alone, but what they do is, in principle, no different from what Galton’s crowd did. They integrate perspectives and the information contained within them. The only real difference is that the process occurs within one skull.

“Need for cognition” is the psychological term for the tendency to engage in and enjoy hard mental slogs. People high in need for cognition are the sort who like crosswords and Sudoku puzzles, the harder, the better—and superforecasters score high in need-for-cognition tests.

This is granularity as bafflegab.
