Is America Safe For Democracy?

The just assembled American army of WWI was soon subject to mass intelligence measurement under the direction of Robert M. Yerkes, president of the American Physiological Association, an organization recently invented by Wundtian protégé G. Stanley Hall. Results published after the war showed remarkable correlation with similar tests on American school children. While Yerkes was reporting these findings to the National Academy of Sciences, famous psychologist Dr. William McDougall was summarizing the civilian studies for the general public in his book, Is America Safe for Democracy? Latins and Slavs in fair mental competition scored significantly lower than native whites, he said. How, then, could they be given a vote equal to white men?
