A list of the most interesting academic and popular articles shared in our network.
Welcome to the Aporia Research Roundup. Every Monday (at 7am New York, 12pm London), we compile the most interesting studies and articles being shared in our network.
The first three links are always free, but we put our favourites (including the less politically correct ones) behind a paywall.
Conventional twin studies overestimate the environmental differences between families relevant to educational attainment. Tobias Wolfram and Damien Morris argue that the Classical Twin Design overestimates the shared environmental influence on assortative mating because it doesn’t account for assortative mating.

Estimating the Payoff to Attending a More Selective College: An Application of Selection on Observables and Unobservables. In a classic article from 2002, Stacy Dale and Alan Krueger compare students who attended selective colleges to those who were accepted at such colleges but decided to study elsewhere. They find that students who attended selective colleges earned about the same as their counterparts who decided to study elsewhere.
Intelligence and school grades: A meta-analysis. Bettina Roth and colleagues carry out a meta-analysis of the relationship between intelligence and school grades, and obtain a value of ρ = .54 after correcting for measurement error and range restriction (r = .44 before correction).
