Philip Tetlock

“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.”

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