MINDSPACE: The Nine Forces That Shape Human Behavior

What is MINDSPACE?

The MINDSPACE framework is a public-policy checklist developed in 2010 by Paul Dolan, Michael Hallsworth, David Halpern, Dominic King, and Ivo Vlaev. Its practical guide complements other policy approaches.

The nine MINDSPACE elements

The acronym names Messenger, Incentives, Norms, Defaults, Salience, Priming, Affect, Commitments, and Ego. The public-service examples below are hypothetical design questions, not tested recommendations.

Messenger

The source of information matters. For a service invitation, compare a familiar local organization with an unfamiliar central office. Ask applicants whom they trust and whether they recognize the sender before assuming a more prestigious signature will help.

Incentives

Rewards and costs can influence action. Suppose submitting a form requires taking time off work. The lost pay is part of the applicant’s decision, even if the application itself is free. Identify that cost before adding a prize for completion.

Norms

Other people’s behavior and approval provide social information. A team might consider telling applicants that others in their situation use the service. First check whether this is true, relevant, and something applicants want to know. A made-up majority is misleading.

Defaults

A default is the option that applies without an active change. A form could preselect paperless correspondence. That raises concrete questions: Do applicants see the selection, understand it, and have an easy way to choose letters instead?

Salience

Noticeable information can attract attention. Put the application deadline beside the submission button and check whether readers can find it. If every instruction is highlighted, the important date may still be difficult to locate.

Priming

Prior cues may affect later responses. A proposal to add community-themed pictures to an application page, hoping to activate cooperation, would be a behavioral-priming hypothesis. It would need direct testing; the word “priming” does not establish the proposed effect.

Affect

Emotional associations can shape responses. An applicant may experience an official-looking envelope as reassuring or threatening. Ask how recipients interpret the material rather than assuming a friendly photograph creates the intended feeling.

Commitments

Promises can create pressure for consistency. An applicant could voluntarily agree with a support worker to bring documents on Tuesday. Check whether the agreement is realistic and whether the person needs help obtaining the documents.

Ego

Self-image can influence choices. Someone who values independence may experience an offer of help as a threat to that identity. Interviews could investigate this possibility; it would be premature to label all non-applicants as too proud to seek support.

What study examples show

Norms:

In Goldstein and colleagues’ first hotel experiment (2008), rooms received either an environmental appeal or a sign describing other guests’ towel reuse. Recorded reuse on the first eligible day was 44.1% with the norm message and 35.1% with the environmental appeal. This is evidence about a particular message comparison and outcome, not proof that a local norm is always the strongest intervention.

Defaults:

Madrian and Shea examined one company’s switch from employees actively enrolling in its retirement plan to automatic enrollment with an opt-out. Participation was higher afterward, and many employees retained the default contribution and fund allocation. This was a company policy-change study, not a randomized comparison of every possible default. It also shows why participation and the amount saved are separate outcomes.

Salience:

In Chetty, Looney, and Kroft’s grocery-store experiment (2009), posting tax-inclusive prices reduced demand for treated products by 8%. The finding concerns making the full price visible; it does not imply that any larger label produces an 8% change.

How to apply MINDSPACE: six supporting actions

The guide identifies six actions. Here is an illustrative application to missed public-service applications:

1. Explore — understand the context. Define the target: eligible residents submit a complete application before the deadline. Speak with applicants, non-applicants, and staff. Examine where attempts stop.
2. Enable — address barriers. If residents cannot obtain a required document, create a workable route to it or review the requirement. A reminder cannot supply a document.
3. Encourage — select ways to influence action. If research identifies an overlooked deadline, test a clearer invitation. Explain why the selected change should address that finding.
4. Engage — involve affected people. Discuss the proposed change with residents. Ask about privacy, unwanted pressure, and acceptable contact methods; change the proposal in response.
5. Exemplify — align the organization’s conduct. If applicants must meet a deadline, staff should also meet promised response dates. Check that different departments give consistent instructions.
6. Evaluate — assess results. Compare completed applications with an appropriate comparison group. Record errors, complaints, staff workload, and who still cannot apply. Use the results to revise the service.

Evidence and practical limits

Priming claims need specific checks.

Doyen and colleagues (2012) tested whether exposure to words associated with older people led participants to walk more slowly. Their first experiment, using automated timing, did not reproduce the effect. In their second experiment, slower walking appeared only when experimenters expected it. This raises questions about that procedure and its interpretation. It is not a finding that every kind of priming is false.

Published effects are not a forecast for a new service.

DellaVigna and Linos compared 126 trials from two US nudge units with a separate sample of published academic trials. Average effects were 1.4 versus 8.7 percentage points. Publication bias and differences between the samples helped explain the gap. These are averages for the studied interventions, not a measured effect of MINDSPACE or proof that scaling an identical intervention necessarily shrinks its effect.

Structural barriers can require structural changes.

Chater and Loewenstein argue that focusing on individual behavior can divert attention from changes to institutions and rules. In the application example, restrictive eligibility, inaccessible offices, or insufficient service capacity may matter more than the invitation. Changing those conditions should remain part of the decision.

MINDSPACE vs EAST and COM-B

EAST stands for Easy, Attractive, Social, and Timely. It organizes intervention ideas around reducing difficulty, attracting attention or interest, using social influences, and choosing an appropriate moment. It offers another way to examine an invitation or service process.

COM-B asks how capability, opportunity, and motivation interact to produce behavior. For an incomplete form, it directs attention to questions such as whether someone understands the questions, can access the necessary records, and wants or feels able to proceed. MINDSPACE can then help generate ideas for an identified problem. None of these labels replaces investigation, an acceptable design, or evaluation.
