Although Negroes tend to perform less well on mental aptitude tests than whites and Orientals, Charles Murray pointed out in his book Facing Reality: Two Truths About Race in America that when blacks, whites, and East Asians get the same scores, blacks still tend to perform less well.
This is how you sound, this report was written 98 years ago and you for some reason still buy into this propaganda:
Selected Assumptions about the Performance of African-American Soldiers in Previous Wars:
It is generally recognized that the pure blood American negro is inferior to our white population in mental capacity. . . . The cranial cavity of the negro is smaller than the white; his brain weighing 35 ounces contrasted with 45 for the white.
All officers, without exception, agree that the Negro lacks initiative, displays little or no leadership, and cannot accept responsibility. Some point out that these defects are greater in the Southern Negro. . . .
Due to his susceptibility to ‘Crowd Psychology’ a large mass of negroes, e.g., a division, is very subject to panic. Experience had indicated that the negroes produce better results by segregation and cause less trouble. Grouping of negroes generally in the past has produced demands for equality, both during war and after demobilization. . . .
An opinion held in common by practically all officers is that the negro is a rank coward in the dark. His fear of the unknown and unseen will prevent him from ever operating as an individual scout with success. His lack of veracity causes unsatisfactory reports to be rendered, particularly on patrol duty. . . .
One of the peculiarities of the negro as a soldier is that he has no confidence in his negro leaders, nor will he follow a negro officer into battle, no matter how good the officer may be, with the same confidence and lack of fear that he will follow a white man. This last trait has been so universally reported by all commanders that it can not be considered as a theory—the negroes themselves recognize it as a fact. . . .
The negro needs trained leadership far more than the white man needs it, and above all they need leaders in whom they have confidence, and whose presence they can feel and see at all times. . . .
On account of the inherent weaknesses in negro character, especially general lack of intelligence and initiative, it requires much longer time of preliminary training to bring a negro organization up to the point of training where it is fit for combat, than it does in the case of white men. All theoretical training is beyond the grasp of the negro—it must be intensely practical, supplemented by plain talks explaining the reasons for things in simple terms. . . . -The 1925 Army War College Report
