Facing a similar problem -- how to extract theoretical insights from their intuitions -- researchers often turned to ``anomalies:'' constructed examples that highlight flaws in an existing theory and spur the development of new ones.

We propose a unified methodology for the robust design and evaluation of predictive algorithms in selectively observed data under such unobserved confounding.

An interesting feature of our framework is that conventional standard errors tend to become more conservative when treatment probabilities vary more across units, i. e. when there is more selection into treatment.

We refer to this phenomenon as "bias reversal."
