One of the best clips I know about how hard it is to hear that you are wrong runs 17 minutes.
In 2024 the actor Terrence Howard told Joe Rogan’s audience that Neil deGrasse Tyson had “attacked” his treatise. It argues that one times one equals two. Tyson’s reply shows what happened eight years earlier. He had read all 36 pages and marked them up in red.
“In my field we call that a peer review,” he says. His notes open by calling the work the sign of “a restless, active mind”. Then they list what is “under-informed, misinformed, or simply false”. He was blunt, he wrote, out of respect for the effort.
Tyson then names the trap. You can know enough about a subject to think you are right, but not enough to know you are wrong. “It’s called the Dunning–Kruger effect.”
Is the effect real? Partly. In the 1999 study, students who scored in the 12th percentile placed themselves in the 62nd. That gap keeps turning up.
But the popular version, that the ignorant feel like experts, is not what was found. The weakest students still rated themselves below the strongest. The finding is about one skill at a time, not about intelligence.
The cause is disputed too. Critics have shown that random numbers produce the same chart. Two ordinary things do it: regression toward the mean, and the habit most of us have of rating ourselves above average. David Dunning answered in 2022 that the effect survives when both are controlled for.
I draw two lessons. First, I try not to hang the label on a person. The finding covers all of us outside our own field, and those who most need to reflect are the least open to it. On most subjects that includes me. It is fair to say that one times one is not two. It is not fair to diagnose the man who says it.
Second, the remedy does not wait on the statistics. Nobody can grade their own paper. An honest review from someone who knows more is a gift, even in red ink, and respect, not ridicule, is how Tyson delivered it. He closes with a saying he credits to Michael Dell: if you find yourself the smartest person in the room, change rooms.
