When there’s more demand than supply, and charging higher prices isn’t an option – or just wouldn’t be fair – markets turn to a familiar strategy: making people wait. Whether it’s to see Michelangelo’s ceiling at the Sistine Chapel or score a free ticket to Shakespeare in the Park in New York, first-come, first-served rules kick in. But not all waits are created equal, and the way a market handles the line says a lot about what kind of experience you’re in for.

There are two main kinds of waiting systems. One involves lists: you sign up and go about your day. The other involves lines: you show up and stay put. Lines are more expensive because they eat up your time in real time. Your opportunity cost – what you could’ve been doing instead – becomes the price you pay. That might mean giving up work hours, a relaxed breakfast, or a chunk of sightseeing.

In many markets, success comes down to following clear, rule-based systems. Think of airline seat assignments or concert ticket queues. You follow the steps, and if you're fast or lucky enough, you get what you want. But not every market works like that. Some of the most important ones in life,  jobs, relationships, school admissions, run on something messier: personal judgment. These are choose-me markets.

In a choose-me market, someone is actively selecting you. And you're also choosing them. It’s not just about being qualified; it’s about being the right fit. Employers, partners, admissions teams: they want to know who you are, what you bring, and whether you're likely to stick around. This shifts the strategy. It’s not just about standing out. It’s about standing out to the right people, in the right way.

In any market packed with options, just being available isn’t enough. You have to stand out. As we’ve seen, the way to do that isn’t always by shouting louder. It’s by sending the right signal at the right time to the right person. Let’s take a closer look at online dating. 

Swipe-based apps like Tinder or Hinge are built to streamline matching. But when millions of people are swiping every day, things can spiral. A growing number of users, especially men, game the system by swiping right on every profile – treating the process like a lottery. This creates a messy dynamic. For women on the app, especially those looking for meaningful matches, a right swipe becomes meaningless. It’s impossible to tell if it’s real interest or just spam.

Some markets give you the freedom to change your mind without consequences. This flexibility is called free disposal, and it’s everywhere: gym class sign-ups, restaurant reservations, job offers, even college acceptances. You can commit early, cancel late, and no one sends a bill. But when too many people use that flexibility as a strategy – hoarding slots they might not use – things break down. That’s when market designers step in to add friction.

Take the luxury fitness gym Equinox. Members can book premium fitness classes in advance, and the temptation to grab multiple time slots “just in case” is strong. But if too many people do this, actual demand becomes impossible to predict. Empty spots go unfilled, while others remain stuck on the waitlist. To stop this, Equinox now limits you to one class per category per day. Cancel too late or no-show too often, and you’ll lose booking privileges.
