Friction: add it to bad habits, remove it from good ones

Friction is time, steps, and awkwardness between you and an action. Ten extra seconds is enough to reroute an evening, because the brain likes the path that is already greased. Wendy Wood and David Neal's context-and-automaticity story is, in practical terms, a friction story. The incumbent behaviour is the one with the fewest steps in that room.

Popular advice says "try harder." Friction says "change the number of steps." Trying harder is willpower. Changing steps is design. Thomas Webb and Paschal Sheeran's intention-behaviour gap is what you get when you try harder in an unaltered kitchen.

Seconds at the decision point

The decision point is often not a meeting. It is a hand hovering over a biscuit tin, a thumb over an icon, a body hovering over a sofa. Charles Duhigg popularised cue-routine-reward as a loop. Friction edits the middle box: make the unwanted routine longer to start, make the wanted routine shorter to start. Duhigg is a populariser of the loop, not a tribologist. You do not need a trial of "ten seconds" to believe your own kettle.

Remove steps from the wanted action

Shoes by the door. Book on the pillow. App on the first screen, or better, a widget that is the first screen. Glass on the sink. BJ Fogg's Tiny Habits method is friction work on ability: if the action is tiny and near, motivation can be low. Peter Gollwitzer's if-then names the moment those saved seconds matter: if I hang the bag, then I put on the shoes that are already there. If the shoes are in a cupboard, the then has unpaid labour in it.

Add steps to the unwanted action

Log out. Delete the shortcut. Put the tin on a high shelf in a box you cannot open one-handed. Move the charger to another room. The point is not to become a person who never wants the thing. The point is to let the want cool for thirty seconds, which is often long enough for a rival then to run. Wood would say you have changed the context so that the old response is less automatically retrieved.

Adding steps to the unwanted

Unwanted habits are often very good habits: well-cued, low-friction, frequently rewarded. A lecture does not compete with that. A delay might. Do not confuse delay with prohibition theatre. A lockbox you will not use is costume. A television that needs the HDMI cable fetched from a drawer is a delay you will actually feel.

Social friction counts

Other people are context. If the household keeps the biscuits on the table, your private rule is a weak if. Negotiate the table. If you cannot, build a personal high-friction path (your share lives in your room, in a box) rather than a daily argument that you will lose when you are tired. This is not a personality verdict. It is a map of cues.

Digital friction is still friction

App limits, grayscale, logging out, and moving icons are small taxes. They work until you build a workaround. Workarounds are information: the want is strong, so the should needs a better cue, not only a tax. Gollwitzer can supply a replacement then: if I unlock the phone after 9 p.m., then I open the reader, not the feed. The tax makes that then cheaper to obey.

Removing steps from the wanted

People hide the wanted action in the name of tidiness. Mats rolled in cupboards. Guitars in cases in other rooms. Journals in drawers. Tidiness is friction on the wrong side. Leave one ugly object in the path. Lally and colleagues (2010, European Journal of Social Psychology) found that automaticity took a median of about 66 days to plateau, range 18 to 254. That is a long time to keep fetching a mat. Leave the mat out until the cue is the mat, not the fetching.

Action	Lower friction	Higher friction
Evening walk	Shoes, keys, and a jacket on one hook	Shoes in a wardrobe behind a suitcase
Phone in bed	Charger in the kitchen	Charger on the pillow
Snack at 10 p.m.	Fruit in a bowl	Biscuits on the sofa arm
Practice guitar	Guitar on a stand in the room you actually sit in	Guitar in a case in a cupboard

Webb and Sheeran would not be surprised that intending to "be more disciplined about snacks" does little if the tin is still the nearest object. Fogg would shrink the wanted action until the remaining steps are trivial. Duhigg's reward can be a close yes: the walk is allowed to be pleasant. Pleasure is not the enemy of friction work. Pleasure is what you attach to the low-friction path.

One extra tap is enough to change a default. Move the wanted app to the dock. Take the unwanted app off the first page. Defaults are context you do not notice, which is why Wood's account keeps beating slogans: the incumbent path is the one you can complete half-asleep. Design for the half-asleep person, because that is who arrives at 10 p.m. Gollwitzer's sentence still helps, but it helps more when the then is already the nearest object.

Habit AI's home-screen widgets remove a step from logging and remembering: the cue is already in the visual field, which is friction taken off the wanted tick and left on the forgotten day.
