Best case scenario for Foroughi et al’s memory theory under the assumption that everyone in a subpopulation of size p satisfies the theory without exception. Each of the bottom four rows contains the effect size d and upper bounds on qi, the proportion of variance attributed to individual differences, for six different values of p.
