"I'll exercise tomorrow morning." That's an intention. A good one. But tomorrow morning there's the alarm, then the coffee, then something else – and the exercise doesn't happen.
Not because you don't want it to. But because there's a gap between wanting and doing. And the ADHD brain falls into that gap very reliably.
If-then plans close that gap.
Peter Gollwitzer, psychologist at the University of Konstanz and NYU, investigated a simple research question in the 1990s: what distinguishes intentions that get carried out from those that don't?
His answer: the link between situation and behavior.
Regular intentions say what you want. Implementation intentions say when and where you'll do it: "If X happens, then I will do Y."
"If I've gotten up and made my coffee, then I'll immediately do 5 minutes of stretching." That's no longer just an intention. It's an if-then link.
Gollwitzer and Sheeran (2006) meta-analyzed 94 studies. Implementation intentions increased the likelihood of goal achievement by an average of 28 percentage points. That's substantial.
The ADHD brain has a specific weakness: it responds very well to immediate, current stimuli – and less well to abstract future plans.
An intention ("I'll exercise more") lives in the future. It has no immediate connection to the present. The ADHD brain doesn't forget it – it just doesn't see it when it would be relevant.
An if-then link is different. It's tied to a specific situation. When that situation occurs, the link activates – almost automatically, without you needing to actively think about it.
That compensates for exactly what's difficult in ADHD: remembering at the right moment.
Not every if-then link works equally well. A few principles:
1. The "if" needs to be concrete
"If I have time" doesn't work – you'll never explicitly "have time." Better: "When I come back to my desk after the lunch break." Concrete, unambiguous situations.
2. The "then" needs to be specific
"Then I'll be more productive" doesn't work. Better: "Then I open the document I'm working on and write for 10 minutes." A clearly defined action.
3. Link to existing routines
The strongest "if" is a moment that already reliably happens: after waking up, after coffee, after lunch. Attach new behaviors to old anchors.
4. Anticipate obstacles
"If I don't feel like exercising, I'll put my running shoes on anyway." That's also an if-then plan – for the likely obstacle. Try building if-then plans for your own excuses.
5. Write it down, don't just think it
The plan in your head is fleeting. Write it down. Put it somewhere visible. The brain needs external reminders – if-then plans are internal in structure, but their representation should be external.
Intention: "I want to drink more water."
If-then plan: "When I take my phone off the charger in the morning, I drink a glass of water first."
That's it. A few sentences. But the specificity makes the difference. Taking the phone off the charger is a trigger that happens every day. It automatically pulls the drinking behavior along with it.
Gollwitzer & Sheeran (2006) showed in their meta-analysis that implementation intentions are especially effective for people who have difficulty with action initiation – which is a core problem in ADHD.
Wieber et al. (2010) explicitly studied ADHD and implementation intentions. Result: people with ADHD benefited more from if-then plans than the control group. The gap between intention and behavior measurably closed.
If-then plans aren't magic. But they're an evidence-based tool – and one that's especially well-suited for ADHD brains.

If-Then Plans
Making decisions in advance – before the ADHD brain interferes
The Problem with Good Intentions
"I'll exercise tomorrow morning." That's an intention. A good one. But tomorrow morning there's the alarm, then the coffee, then something else – and the exercise doesn't happen.
Not because you don't want it to. But because there's a gap between wanting and doing. And the ADHD brain falls into that gap very reliably.
If-then plans close that gap.
What Implementation Intentions Are
Peter Gollwitzer, psychologist at the University of Konstanz and NYU, investigated a simple research question in the 1990s: what distinguishes intentions that get carried out from those that don't?

Why This Especially Helps with ADHD
The ADHD brain has a specific weakness: it responds very well to immediate, current stimuli – and less well to abstract future plans.
An intention ("I'll exercise more") lives in the future. It has no immediate connection to the present. The ADHD brain doesn't forget it – it just doesn't see it when it would be relevant.

How to Build Good If-Then Plans

An Everyday Example
Intention: "I want to drink more water."
If-then plan: "When I take my phone off the charger in the morning, I drink a glass of water first."
That's it. A few sentences. But the specificity makes the difference. Taking the phone off the charger is a trigger that happens every day. It automatically pulls the drinking behavior along with it.
