Economists spent 200 years assuming humans make perfect decisions, until a political scientist proved we just grab the first option that's good enough, won the Nobel Prize in economics for it, and then taught a machine to think the exact same way. I read this and immediately thought about every decision I made today. Not one of them was perfect. All of them were good enough. His name was Herbert Simon. The book is called Administrative Behavior. It started with a college paper about playgrounds. In 1935, Simon was a student in Milwaukee studying how the city spent its parks budget. He expected the managers to weigh every option and pick the one that gave the city the most value. That's not what he saw. The people who maintained the playgrounds wanted the money for repairs. The people who ran activities wanted it for staff. Nobody was comparing every possible choice. Each side just pushed for what looked reasonable from where they stood, and they called it a day. That small observation broke something huge. Economics was built on a fantasy person. Economists called him "economic man." He knows every option. He has unlimited time. He calculates the perfect choice every single time. Simon looked around and asked one question. Who actually lives like that? Nobody does. Your brain has a small amount of attention and a short amount of time. So instead of searching for the best choice, you search until you find one that clears the bar, and then you stop. You do it all day without noticing. - You park in the first open spot, not the closest one - You pick a restaurant after reading three reviews, not three hundred - You hire the first candidate who checks the boxes - You take the job offer before seeing every other job on Earth Simon gave this a name. Satisficing. Satisfy plus suffice. And he gave the bigger idea a name too. Bounded rationality. We are rational, just inside walls we can't climb over. He wrote about the real enemy decades before anyone had a smartphone. "A wealth of information creates a poverty of attention." In 1978, the man who wasn't an economist won the Nobel Prize in economics for telling economists their perfect human didn't exist. But that wasn't even his most important work. Back in 1955, Simon and his colleague Allen Newell asked a wild question. If humans solve hard problems with shortcuts instead of checking every possibility, could a machine do the same? They built a program called the Logic Theorist. They gave it a famous math book full of proofs that took two of the greatest minds in philosophy years to write. The program didn't try every path. That would take forever. It used rules of thumb to chase the paths that looked promising and skip the rest. The same way you skip the parking spots at the far end of the lot. It proved 38 of the first 52 theorems. One of its proofs was cleaner than the original. In January 1956, Simon walked into his class and told his students: "Over Christmas, Allen Newell and I invented a thinking machine." It became one of the very first AI programs ever written. Think about the loop he closed. He studied why humans can't be perfect. Then he built a machine that worked because it stopped trying to be perfect too. We keep asking AI to be flawless. The man who helped invent it already knew the secret. Good enough is how every mind gets anything done.
