The economics of social signals.
Economist Michael Spence's 1973 research asked a deceptively simple question: why does education affect wages so dramatically, even when much of what people learn in school has nothing to do with their jobs?
Education, he argued, works as a costly status marker. A degree from a competitive university doesn't directly prove you'll be a good employee. What it proves is that you could survive the process. You could handle the workload, pay the tuition, navigate the system, and delay gratification for four years. The credential is credible precisely because it hurts to produce.
But here's where it gets interesting. Spence found that talented people find it easier to get through school than less talented people. Not because the classes are simpler for them, but because the psychological cost is lower. They struggle less. So for them, the credential is cheaper to acquire.
This sets up a sorting mechanism. Capable people tend to get degrees, less capable people tend not to, and employers learn to use the credential as a shortcut. They don't know what the degree taught you. They just know that having one correlates with being the kind of person they want to hire.
The problem is what happens next. Once a bachelor's degree becomes common, it stops separating anyone. So the master's degree becomes the new filter. Then the MBA. Then the internship at the right firm. The bar keeps rising, and people keep investing more resources into clearing it. Not because the extra education makes them more capable. Just because they need to stay ahead of everyone else doing the same thing.
And yet, for all their effort, status decays. What counts as "impressive" shifts, depending on the market. The MBA that opened doors in 2005 carries less weight in 2025. Status is borrowed credibility, and the lender can change the terms. Signal doesn't work that way. What you can actually do stays with you, compounds quietly, and transfers to whatever comes next.
The way out is to ask a different question.
Instead of, what will this look like to others?
Ask, what will this make me capable of?
That's the difference between status and signal. One requires an audience. The other compounds, whether anyone is watching or not.
