Personality Tests

I want to quote the first few paragraphs of this in full.

When Alexander (Sandy) Nininger was twenty-three, and newly commissioned as a lieutenant in the United States Army, he was sent to the South Pacific to serve with the 57th Infantry of the Philippine Scouts. It was January, 1942. The Japanese had just seized Philippine ports at Vigan, Legazpi, Lamon Bay, and Lingayen, and forced the American and Philippine forces to retreat into Bataan, a rugged peninsula on the South China Sea. There, besieged and outnumbered, the Amer-icans set to work building a defensive line, digging foxholes and constructing dikes and clearing underbrush to provide unobstructed sight lines for rifles and machine guns. Nininger's men were on the line's right flank. They labored day and night. The heat and the mosquitoes were nearly unbearable.

Quiet by nature, Nininger was tall and slender, with wavy blond hair. As Franklin M. Reck recounts in "Beyond the Call of Duty," Nininger had graduated near the top of his class at West Point, where he chaired the lecture-and-entertainment committee. He had spent many hours with a friend, discussing everything from history to the theory of relativity. He loved the theatre. In the evenings, he could often be found sitting by the fireplace in the living room of his commanding officer, sipping tea and listening to Tchaikovsky. As a boy, he once saw his father kill a hawk and had been repulsed. When he went into active service, he wrote a friend to say that he had no feelings of hate, and did not think he could ever kill anyone out of hatred. He had none of the swagger of the natu-ral warrior. He worked hard and had a strong sense of duty.

In the second week of January, the Japanese attacked, slipping hundreds of snipers through the American lines, climbing into trees, turning the battlefield into what Reck calls a "gigantic possum hunt." On the morning of January 12th, Nininger went to his commanding officer. He wanted, he said, to be assigned to another company, one that was in the thick of the action, so he could go hunting for Japanese snipers.

He took several grenades and ammunition belts, slung a Garand rifle over his shoulder, and grabbed a submachine gun. Starting at the point where the fighting was heaviest-near the position of the battalion's K Company-he crawled through the jungle and shot a Japanese soldier out of a tree. He shot and killed snipers. He threw grenades into enemy positions. He was wounded in the leg, but he kept going, clearing out Japa-nese positions for the other members of K Company, behind him. He soon ran out of grenades and switched to his rifle, and then, when he ran out of ammunition, used only his bayonet. He was wounded a second time, but when a medic crawled toward him to help bring him back behind the lines Nininger waved him off. He saw a Japanese bunker up ahead. As he leaped out of a shell hole, he was spun around by a bullet to the shoulder, but he kept charging at the bunker, where a Japanese officer and two enlisted men were dug in. He dispatched one soldier with a double thrust of his bayonet, clubbed down the other, and bayonetted the officer. Then, with outstretched arms, he collapsed face down. For his heroism, Nininger was posthumously awarded the Medal of Honor, the first American soldier so decorated in the Second World War.

Suppose that you were a senior Army officer in the early days of the Second World War and were trying to put together a crack team of fearless and ferocious fighters. Sandy Nininger, it now appears, had exactly the right kind of personality for that assignment, but is there any way you could have known this beforehand? It clearly wouldn't have helped to ask Nininger if he was fearless and ferocious, because he didn't know that he was fearless and ferocious. Nor would it have worked to talk to people who spent time with him. His friend would have told you only that Nininger was quiet and thoughtful and loved the theatre, and his commanding officer would have talked about the evenings of tea and Tchaikovsky. With the exception, perhaps, of the Scarlet Pimpernel, a love of music, theatre, and long afternoons in front of a teapot is not a known predictor of great valor. What you need is some kind of sophisticated psychological instrument, capable of getting to the heart of his personality

There is however no such instrument. All through my MBA and when I have worked for large companies I have had these tests thrown at me and I have never seen any sort of evidence that they are valid at all.
