What this means

A teacher announces that whoever reads the most books this month gets to eat lunch with the principal. Some students immediately start reading. Some students shrug. And one student thinks lunch with the principal sounds terrible and reads less.

Same announcement. Same room. Three completely different reactions.

The announcement was an incentive. Incentives work, but they do not work the same way on everybody. That is not because some people are stubborn. It is because people want different things.

The things a person cares about most are their values. One student values attention from adults. Another values time alone. Another values being funny in front of friends. Another values not letting a teammate down. Those are all fine. They are just different.

So here is the rule. An incentive only works on you if it connects to something you already care about. A prize you do not want is not much of a prize. A consequence you do not mind is not much of a consequence.

That is why a whole class can hear one rule and respond in five different ways.

Why it matters

If you ever try to get someone to do something, and you use the reward that would work on you, it might not work at all. Little kids do this constantly, and so do grown-ups. Understanding values is how you stop guessing.

It also protects you from a bad conclusion. When someone is not motivated by the same thing you are, it is easy to decide they are lazy or weird. Usually they just have a different list of things they care about.

Real-world example

Public libraries often run summer reading programs where kids log books and earn small prizes. Watch who signs up. Some kids join because they want the prize. Some kids were going to read all summer anyway and just like having a chart to fill in. Some kids never sign up, not because they hate reading, but because logging every book feels like homework. One program, one prize, and three totally different responses from kids who all had library cards.

Try it

  1. Make a list of these five things down the left side of a page: read a book, return library books on time, repay money you borrowed from a friend for lunch, do extra credit work, turn in homework on time.
  2. For each one, write down the incentive that would actually get you to do it. Be honest, not polite. If nothing would get you to do extra credit, write that too. That is real data.
  3. Mark each incentive you wrote with a P for positive or an N for negative. Notice which kind you used more.
  4. Now trade papers with a partner. Read their five answers without talking.
  5. Find one place where you and your partner wrote completely different incentives for the same task. Talk about why. Try to finish this sentence about your partner: "This works on you because you care about ______."
  6. As a class, collect answers for just one task, like repaying a friend. List every different incentive on the board. Count how many different ones the room produced.
  7. Write one sentence answering this: why did one class, hearing about one task, come up with so many different answers?

Teacher note

The result you want from step 6 is a long, messy list, so pick the task most likely to split the room. Repaying a borrowed lunch dollar works well, because some students will name a consequence like not being lent money again, while others will name something purely social like not wanting their friend to think badly of them. Those two answers come from genuinely different values, and putting them side by side does more teaching than any explanation you could give.

The main misconception is moral rather than economic. Students quickly decide that whoever needs a prize to read is worse than whoever reads anyway. Head this off before step 4 by saying plainly that different values are not better or worse values. If it comes up anyway, use it: ask whether the student who reads for prizes and the student who reads for fun ended up reading. They both did. The incentive worked on one of them and was unnecessary for the other, and neither is a character flaw.

A second thing to watch for is students who write what they think you want in step 2. You will spot it because every answer is a sticker or a grade. Give them explicit permission to write "nothing would work" for at least one task, and the honest answers usually appear.

A student has it when they can predict, correctly, that a specific incentive will not work on a specific classmate, and can say which value it fails to connect to. A student who is still saying "some people just try harder" has not gotten there. Push them with one question: harder at what, and why that and not something else?

Check yourself

A teacher offers pizza to the student who reads the most books. One student reads six books and another reads none. What is the best explanation?

Why do different students respond differently to the very same reward?

You want a friend to return a book you lent them. Which approach is most likely to work?

An incentive only works if it connects to something the person already cares about, which is why one reward can move half a class and leave the other half unmoved.
