Brains Versus Brawn: Ordinal Rank Effects in Job Training

Using data from Air Force basic military training, Civitas Senior Fellow Scott Carrell and Alexander Chesney examine the impacts of relative rank in cognitive and physical ability on enlistees short and longer-run outcomes. Results show strong evidence for the “big fish, small pond” phenomenon, meaning that individuals of equal ability tend to thrive when they are higher on the proverbial pecking order of ability within their assigned group. Findings also suggest that overall group productivity could be improved by altering the way military personnel are assigned to training groups.
