This Friday, 1-2pm in SEC 1.413, we are very excited to have Sharad Goel (Harvard Kennedy School) speak in-person on:
Included-variable bias and everything but the kitchen sink
Abstract: When estimating the risk of an adverse outcome, common statistical guidance is to include all available factors to maximize predictive performance. Similarly, in observational studies of discrimination, general practice is to adjust for all potential confounds to isolate any impermissible effect of legally protected traits, like race or gender, on decisions. I’ll argue that this popular "kitchen-sink” approach can in fact worsen predictions in the first case and yield conservative estimates of discrimination in the second.
