A WSJ interview with Bill Gates includes this pivotal observation:
“I believe in innovation and that the way you get innovation is you fund research and you learn the basic facts.” Compared with R&D spending in the pharmaceutical or information‐technology sectors, he says, next to nothing is spent on education research. “That’s partly because of the problem of who would do it. Who thinks of it as their business? The 50 states don’t think of it that way, and schools of education are not about research. So we come into this thinking that we should fund the research.”
While it’s true that public school districts don’t spend a lot on R&D, a vast army of academics has been cranking out research in this field for generations. The Education Resources Information Center, a database of education studies dating back to 1966, boasts 1.3 million entries. So the problem is not a lack of research, but rather that most of the research is useless and that the rare exceptions have been ignored by the public schools.
Why? Because, as Bill Gates correctly observes, hardly anyone thinks of education as their business. And how do you get masses of brilliant entrepreneurs to think of education as their business? You make it easy for them to make it their business. When and where education is allowed to participate in the free enterprise system, entrepreneurs enter that field just as they do any other–and excellence is identified and scales up. It is a process that happens automatically due to the freedoms and incentives inherent in that system. More than that, it is the only system in the history of humanity that has ever led to the routine identification and mass replication of excellent products and services.
So what happens if you want market outcomes but reject the market system that creates them? You are left to re‐invent the wheel… without the only value of pi that makes a circle.
