Conditional Cooperation

“Your willingness to contribute may shift with what you expect from everyone else.”

01 / PLAINLY

What it means, plainly

Conditional cooperation occurs when someone's willingness to contribute changes with what they expect others to contribute.

02 / CONTEXT

A little more

In public-goods experiments, many participants contribute more when they expect larger contributions from the group. They coexist with more self-interested or unconditional types, so composition and information matter.

03 / WHY IT MATTERS

Why it matters

Making credible commitments visible may encourage contributions, but groups still contain different motives and responses.

04 / EXAMPLE

A familiar example

In a neighborhood fund, someone agrees to pay more after seeing verifiable commitments from other households.

05 / LIMIT

What it does not mean

Not all cooperation is imitative calculation, and a laboratory rate cannot predict every community.

06 / NOTICE

Notice it in your day

Imagine a neighborhood fund and write what you would contribute with no information and after seeing verified commitments. Name the expectation that changed without treating your response as universal.

FINAL NOTE

The idea worth keeping

Make credible commitments visible without assuming everyone will respond alike.
