MINDSPACE, letter by letter, and where a witnessed alarm fits

A 2010 UK government report opened its case with a complaint about its own field. Behavioural economics, it said, had accumulated “literally hundreds of different claimed effects,” some resting on “just one or two studies.” The authors picked the nine they considered repeatedly found and arranged them under an acronym.

MINDSPACE is that acronym: Messenger, Incentives, Norms, Defaults, Salience, Priming, Affect, Commitments and Ego. Paul Dolan, Michael Hallsworth, David Halpern, Dominic King and Ivo Vlaev wrote the report for the Cabinet Office, published by the Institute for Government, and the group plus Robert Metcalfe described it in the Journal of Economic Psychology in 2012 as a mnemonic for the nine most robust effects shaping behaviour, mostly automatically. The report itself says the list “may not reflect an exhaustive categorisation.” It is a curated checklist for policymakers, not a theory that makes predictions.

What are the nine effects, with the report’s own examples?

Letter	The report’s one-line gloss	Example the report gives
Messenger	We are heavily influenced by who communicates information	Health interventions delivered by health educators beat those delivered by teachers or trained facilitators
Incentives	Responses are shaped by predictable shortcuts such as strongly avoiding losses	Weight-loss deposits returned only if targets were met produced significant loss after seven months; controls did not change
Norms	We are strongly influenced by what others do	Hotel towel signs: 35.1% reuse for an environmental appeal, 44.1% when most guests reuse, 49.3% when most previous occupants of the room did
Defaults	We “go with the flow” of pre-set options	Ventilators set to lower lung volumes by default: mortality 25% lower, trial stopped early
Salience	Attention goes to what is novel and seems relevant	Tax shown on the shelf label of 750 products cut sales 8% over three weeks
Priming	Acts are influenced by sub-conscious cues	Moviegoers ate 45% more popcorn from a 240g container than a 120g one
Affect	Emotional associations shape actions	A Ghana soap campaign built on disgust rather than product benefits lifted soap use after the toilet by 13%
Commitments	We seek consistency with public promises, and reciprocate	A signed walking contract: 81% met the goal, against 31% without one
Ego	We act in ways that make us feel better about ourselves	Sports fans misremember fouls, seeing more by the opposing team than an impartial observer does

Two entries deserve a second look. The Norms section also records a failure: a national park sign showing three thieves taking wood increased theft by 7.92%, while a sign showing one thief increased it by 1.67%. Describing a bad behaviour as common advertises a norm. And the report is unusually candid about Priming, calling it “perhaps the least understood of the MINDSPACE effects.”

It is also the shakiest. The report’s elderly-word example, in which people walked more slowly after seeing words like “wrinkles,” was the target of a 2012 PLOS ONE replication by Doyen, Klein, Pichon and Cleeremans, who used infrared timing and reported the slowing only when experimenters expected it. The dispute is not fully settled, but the report’s “real and robust” label for priming has aged worse than its popcorn container.

Where a witnessed morning alarm fits

Take a witnessed alarm: one that makes a missed wake-up visible to friends. DontSnooze is one example, and the audit below applies to the category. It is an application of the framework, not a test of it, because nobody has run a MINDSPACE-coded experiment on waking up.

Used heavily: Commitments, Incentives, Affect. The report says commitments “usually become more effective as the costs for failure increase,” and names making them public as the common method, because breaking one means reputational damage. A witnessed alarm is that sentence implemented. It also matches the Incentives section’s advice to frame the incentive as a charge imposed for failure, as in the weight-loss deposit, except the currency is embarrassment instead of money. The report’s fifth insight, that “we live for today at the expense of tomorrow,” argues for immediacy, and a penalty that arrives soon after the miss fits that better than a fine mailed later. Affect is the passenger: the anticipated discomfort of friends seeing a bad photo. The report warns against creating “fear without agency,” and the alarm avoids that because the escape (getting up) is obvious.

Defaults are used by inversion. Most phones ship the same nine-minute snooze interval, so the pre-set outcome of inaction is more sleep. A witnessed alarm reverses the default outcome of doing nothing. The caveat is that the user chose this setup once, in advance, which is a smaller default than an opt-out form that fires without anyone choosing.

Messenger, Norms, Salience, Priming and Ego are thin or absent. Messenger is the instructive miss. The friends are an audience, not a source of information, and the report’s Messenger evidence concerns how persuasive information is, not how watched behaviour is. Paid knocker-ups, who woke people before alarm clocks were common, were a Messenger in the report’s sense, a particular person whose wake-up call carried weight. A friend who only receives a photo is not. Norms appear only if friends also use it, and the park-sign result suggests that a feed of failures could normalise failure. Nothing in the category addresses Priming or Ego directly.

The framework also has a blind spot that matters at 6 a.m. Most of its examples are choices made while alert. Sleep inertia research concerns the minutes when the person making the choice is the least capable of it, and MINDSPACE does not model capability at all. A checklist of automatic influences is a poor fit for that moment.

One more limit: Incentives and Commitments only work if the evidence is real. Common tactics for faking the proof reduce a witnessed alarm to a commitment device with an exit, and the report’s crowding-out warning applies too, since an external penalty can erode the intrinsic motive it replaces.

Tally: three letters used heavily, one by inversion, five largely untouched.
