Philip E. Tetlock

beliefs are hypotheses to be tested, not treasures to be guarded.

The intellectually aggressive hedgehogs knew one big thing and sought, under the banner of parsimony, to expand the explanatory power of that big thing to “cover” new cases; the more eclectic foxes knew many little things and were content to improvise ad hoc solutions to keep pace with a rapidly changing world.

How you think matters more than what you think.
