"Austrian mathematician Abraham Wald was a World War II hero. He worked out of a nondescript apartment building in Harlem for the Applied Mathematics Panel. Wald’s ability to see the unseen was a significant factor in the Allied victory in World War II.

Allied bomber planes were being shot down at such an alarming rate that bomber airmen were called “ghosts already.” The Air Force concluded that more armor was needed on the planes but adding armor would add weight. David McRaney, the author of several books on cognitive biases, tells the story of how Wald saved the military from a major blunder:

“The military looked at the bombers that had returned from enemy territory. They recorded where those planes had taken the most damage. Over and over again, they saw that the bullet holes tended to accumulate along the wings, around the tail gunner, and down the center of the body. Wings. Body. Tail gunner. Considering this information, where would you put the extra armor? Naturally, the commanders wanted to put the thicker protection where they could clearly see the most damage, where the holes clustered. But Wald said no, that would be precisely the wrong decision. Putting the armor there wouldn’t improve their chances at all.”

Wald looked at the same bullet holes and saw a pattern revealing “where a bomber could be shot and still survive the flight home.”

Wald didn’t fall for survivorship bias. Here is what he advised:

“What you should do is reinforce the area around the motors and the cockpit. You should remember that the worst-hit planes never come back. All the data we have come from planes that make it to the bases. You don’t see that the spots with no damage are the worst places to be hit because these planes never come back.”

We are ignorant of our ignorance. It is time to look for new patterns in the evidence of those who have not survived.

Policy makers, politicians, and the media have largely ignored the cockpit of good health: the human immunological system.

Maher pointed to a recent CDC study that reported the vast majority (78%) of those hospitalized or dead from Covid have been overweight or obese.

Of Americans aged 20 and over 73.6% are overweight; 42.5% are obese. (Obesity is defined as a body mass index (BMI) of over 30.) Many studies explain how obesity decreases resistance to infection. Obesity is linked to type 2 diabetes, hypertension, and heart disease, which increase the odds of hospitalization from Covid.

The Covid survival narrative has focused attention on lockdowns, masks and vaccinations. Maher pointed out the role that obesity played: “People died because talking about obesity had become a third rail in America.” Maher continued, “the last thing you want to do is say something insensitive. We would literally rather die. Instead, we were told to lock down. Unfortunately, the killer was already in the house and her name is Little Debbie.”"
