This isn't about knowledge, but rather performance. It turns out that your performance on geometry and vocabulary tests is highly correlated with your performance on tests in such disparate fields as Classics and Music: https://en.wikipedia.org/wiki/G_factor_(psychometrics)#Cognitive_ability_testing https://en.wikipedia.org/wiki/G_factor_(psychometrics)#Cogni... The crazy result in general intelligence is that your performance in all these areas is highly correlated, and incredibly correlated with career success: > "Research indicates that tests of g are the best single predictors of job performance, with an average validity coefficient of .55 across several meta-analyses of studies based on supervisor ratings and job samples."
