Historiometry
Historiometry is the historical study of human progress or individual personal characteristics, using statistics to analyze references to geniuses, their statements, behavior and discoveries in relatively neutral texts. Historiometry combines techniques from cliometrics, which studies the history of economics and from psychometrics, the psychological study of an individual's personality and abilities.
