If-then plans
This term is defined just below. Read the definition first, then open a page where the term is used, listed at the end.
REFERENCE: ONE TERM
An if-then plan names a moment and an action ahead of time: if this happens, then I will do that.
The decision usually gets made too late. The moment arrives, the old habit is already moving, and the choice you meant to make is nowhere near.
An if-then plan moves the deciding to earlier. You pick the moment and the action now, while you are calm. If this happens, then I will do that. When the moment comes, the choice is already waiting for you.
What it looks like
You know the moment well. A reply is slow and your chest tightens. You start typing sorry before anything has gone wrong. Someone praises your work and the no, it was nothing, is already out.
An if-then plan is written for exactly that moment. If I start typing sorry, I delete it and write thanks. If my chest tightens while I wait, I put the phone down. If they praise the work, I say thank you and stop.
Short is better. The plan has to fit inside a few seconds, because that is all the room you will have.
Implementation intentions
Implementation intentions is the research name for if-then plans. It is the term you will find in papers. It means the same thing: a plan that ties one action to one moment.
This site's Research Library reads several of those papers. In lab experiments, a plan took away the old habit's head start. Without one, the habit came to mind first. With one, that head start was gone.
The new option did not become automatic right away, though. The plan gave people more room to choose. They still had to want the other goal. In another set of lab studies, a goal not to feel fear did less than that goal plus an if-then plan.
Mental contrasting
Mental contrasting is the research name for setting the future you want against what really stands in the way. Picturing the good outcome is the first half. Naming the obstacle is the second.
One small trial read in the Research Library put the two together with children at one school. They named the obstacle, then made if-then plans to get past it. Their grades, attendance and conduct improved compared with a group taught positive thinking.
[FIELD OBSERVATION]
With a pattern, the obstacle is rarely out in the world.
It is usually the moment the pattern starts. That is the moment to plan for.
Where the word stops
An if-then plan is not a promise to be different. A promise covers the future in general. A plan covers one moment you can name.
It is also not enough on its own against a strong habit. One paper found plans helped break weaker habits and did less when the habit was strong. A pattern that has run for years is usually strong. So the plan has to be used every time, not once.
None of these studies tested this method. They tested plans on lab tasks, on feelings shown on slides, on smoking and on school goals.
What to do when you notice it
Write your plan around the body signal. That is the physical feeling that comes first, such as a tight chest, a closing throat or heat in the face. Make that feeling the if.
[FIELD ASSIGNMENT]
If my chest tightens, then I say: this is the old pull, and I do not have to follow it.
Then I do one small different thing. Put the phone down. Say thank you. Leave the room for ten minutes.
When the moment comes, notice the feeling and name what is starting. Say your one short sentence out loud. Then take the different action instead of the usual response.
Count it as one rep, one repetition of the plan in a real moment. If you miss it and only notice afterward, say the sentence then. That still counts, and it makes the next moment easier to see.
The term in use
- If I start typing sorry, then I delete it and write thanks.
- If my chest tightens while I wait, then I put the phone down.
- If they praise the work, then I say thank you and stop.
Often mixed up with
A GOAL
A goal says what you want. An if-then plan says what you will do in one named moment to get there.
A RESOLUTION
A resolution covers the future in general. An if-then plan covers one moment you can recognize when it arrives.
POSITIVE THINKING
Positive thinking pictures the good outcome. Planning also names what stands in the way, and what you will do when it shows up.
Questions people ask about this term
What is an if-then plan?
A plan that names a moment and an action ahead of time. If this happens, then I will do that. You decide while calm, so the choice is ready when the moment comes.
What are implementation intentions?
It is the research name for if-then plans. Papers use the longer term. It means the same thing.
What is mental contrasting?
It is the research name for setting the future you want against what stands in the way. You picture the good outcome, then name the obstacle. Plans then target that obstacle.
Do if-then plans actually work?
In lab studies, a plan took away the old habit's head start. A goal plus a plan did more than the goal alone. The studies were short and mostly in labs.
Do if-then plans work on strong habits?
Less well. One paper found plans helped with weak or moderate habits and did less when the habit was strong. Use the plan every time, not once.
How do I write a good if-then plan?
Make the if a moment you can feel, such as a tight chest. Make the then one small action you can do in seconds. Keep it to one line.
How many if-then plans should I have?
Start with one, for the moment that comes most often. One plan used every time does more than five you forget.
Is an if-then plan the same as a goal?
No. A goal says what you want. The plan says what you will do in one moment to get there.
What if I forget my plan in the moment?
Say it as soon as you remember, even afterward. A late catch still counts as one rep. Then watch for the next moment a little earlier.
Should the if be a situation or a feeling?
For a pattern, a feeling in the body often works best. The situation changes from day to day. The physical feeling tends to come first, the same way.
Is an if-then plan a therapy technique?
It is a term from research on goals and habits. This page uses it plainly. It is not a treatment here.
