I stand by my earlier statement about IQ.
The following facts can be verified in the book "The Reich Marshal: A Biography of Hermann Goering" by Leonard Mosley. I used that text as one of my sources for a paper I wrote while working on my MSE in History.
In 1945, an army psychologist named G.M. Gilbert conducted an IQ test of the top Nazi leaders being prosecuted in the Nuremberg trials.
Hjalmar Schacht 143
Arthur Seyss-Inquart 141
Herman Goering 138
Karl Doenitz 138
Franz von Papen 134
Eric Raeder 134
Dr. Hans Frank 130
Hans Fritsche 130
Joachin von Ribbentrop 129
Wilhelm Keitel 129
Albert Speer 128
Alfred Jodl 127
Alfred Rosenberg 127
Constantin von Neurath 125
Walther Funk 124
Wilhelm Frick 124
Rudolf Hess 120
Fritz Sauckel 118
Ernst Kaltenbrunner 113
Julius Streicher 106
The results delighted Goering, because it showed that the Nazi leaders were far from the illiterate boobs many in the West believed them to be. The average IQ is about 130.
Ergo, IQ is no guarantee of ability or wisdom or moral strength.
