"You are looking only at the survivors," Arthur replied. "Just like Abraham Wald and the bullet holes in World War II."

"Exactly," Arthur said. "And as for the even and odd serial numbers? The even-numbered line runs at a slightly higher temperature due to its physical location near the facility's heating grid. That heat, combined with our heavy-handed voltage test, pushed more of them over the edge. It's not a cursed line; it's just cumulative stress." The Power of Mathematical Thinking

"During World War II, the military wanted to add armor to the parts of returning planes that were covered in bullet holes—the wings and the fuselage," Arthur explained. "The mathematician Abraham Wald told them to do the exact opposite. He said to put armor where the bullet holes weren't —the engines. The planes hit in the engines never came back to be counted. The data was missing the most important variable." "You are looking only at the survivors," Arthur replied

They implemented his plan. Within two weeks, the field failure rate plummeted to less than 0.5%. The even-numbered line runs at a slightly higher
