This just in, from the AP (Associated Philosophers) news:
Weather in Chicago for the upcoming APA this Wed. through Saturday (Feb. 18-21) is expected to be unseasonably warm. When asked to comment, local meteorologists were at a loss for an explanation. “Some of us have developed an hypothesis we call the KVANVIG EFFECT,” said one. “We figure it is yet another occasion when Jon Kvanvig made a doom-and-gloom prediction that failed to materialize. To date this effect had been previously acknowledged only in the domains of philosophy of religion and epistemology, where it is pervasive, but with Jon getting into meteorology, we think it is a reasonable hypothesis that the effect explains the warming patterns.” Professor Kvanvig was not immediately available for comment.
