Identity-Matched Social Norms use truthful information about peer behavior to influence action. The first task is to identify the behavior you want to reinforce and the reference group the audience genuinely identifies with. A broad popularity claim may be less persuasive than evidence about teachers to other teachers, neighbors to neighbors, or existing fans to fellow fans. Measure the real behavior, frame the norm clearly, and share it where the relevant decision occurs. The mechanism combines descriptive evidence with social identity: peers provide a cue that the action is compatible with the group's values and habits. Shankar described homeowners reducing energy use after learning that neighbors used less, and emphasized that norms become more effective when they come from a community or people who share a similar trait.
Origin
Shankar explained social-norm research through household energy use and Hala Taha's experience showing listeners that fellow fans requested a replay.
Core principles
- 01People use peers' behavior as evidence about what fits their group
- 02Norms are stronger when the reference group shares a meaningful identity
- 03Truthful behavioral data can motivate without inventing social proof
How to run it
- 1
Select the behavior
Choose one observable, desirable action. Ensure it is appropriate to encourage for this audience.
- 2
Choose the reference group
Identify peers whose behavior will feel relevant to the audience because they share a role, community, location, or value.
Pro tip Prefer a smaller meaningful group over a large unrelated crowd.
Watch out A mismatched group can make the comparison easy to dismiss.
- 3
Measure the norm
Collect accurate counts or rates for the desired peer behavior. Confirm that the norm is strong enough to reinforce the action.
Watch out Never fabricate popularity or imply a majority that does not exist.
- 4
Make the norm visible
State the fact clearly near the moment of choice. Keep the message specific to the audience and action.
Pro tip Use a concrete count or comparison when it is honest and easy to understand.
- 5
Measure the response
Compare behavior before and after the message or against an untreated group. Stop or revise the norm if it backfires.
Watch out Publishing low participation can normalize the behavior you are trying to change.
In the wild
A company told homeowners when their neighbors were using less energy. The local comparison succeeded where financial incentives, canvassing, and door hangers had not.
→ Homeowners became more motivated to reduce energy use.
Common mistakes
Using generic popularity
A crowd matters less when the audience does not identify with it.
Broadcasting an adverse norm
Showing that few peers take the desired action can accidentally validate inaction.
Is it for you?
Best for
Workplaces and communities with credible participation data and a meaningful shared identity.
Not ideal for
Low-adoption behaviors where publishing the weak norm would signal that inaction is normal.
From the transcript
“we are heavily influenced by how those around us act and behave and if we understand this we can actually leverage it for good”
“the one that did work was telling people when their neighbors were using less energy than they were”
“social norms are even more effective when they're coming from people within a community or people who share a similar trait as you”
