On March 14, UW professors Carl T. Bergstrom and Jevin West shared advice with members and guests on deciphering the signal from the noise. The duo wants to help us better recognize and refute phony science.

Borrowing from their new course, “Calling Bullshit,” they surveyed strategies that writers can use, such as how to sniff out manipulated data and misleading figures — from bogus correlations to deceptive axes.
