Decisions on whether to retain recent hires are often limited by small sample size. We empirically assess whether uncertainty in employee retention decisions could be significantly reduced by increasing sample size. Using a unique data set from professional tennis matches to measure small sample outcomes, we find little difference in giving three chances, relative to five chances, in determining innate ability.
