Recently the ASA published a report urging departments to end using the GRE when considering graduate school applications.

I don’t have too strong an opinion about this. The most persuasive criticism I read was that most of the studies cited are faulty for conditioning on a collider. I’ve also seen this referred to as Berkson’s paradox.

Basically, if you restrict your attention to a nonrandom sample selected on the characteristics you’re interested in studying, you might find the opposite association than that actually exists in the population that matters. If you focus on the relationship between conscientiousness and IQ among folks in college, the slope may be negative. But college admission selects on each of these categories, so in actuality, there is no relationship, or a positive relationship, between these traits.

The criticism of the ASA report is that most of the cited studies fall victim to this faulty logic. Therefore, I thought it would be fun to make some potential headlines of future reports that accidentally fall victim to collider bias (these are satirical, made by me, and are meant to be funny. Whether they are is an open question). Enjoy!
