Implementation intention

Also known as: If–then plan, Implementation intentions

German: Durchführungsintention

In motivation psychology, an implementation intention is a plan of the form “If situation X arises, then I will do Y”, which links a goal to a specific situation and response; Peter M. Gollwitzer described the concept and its effects in 1999.

In one sentence

An implementation intention is an if–then plan that links a goal to a specific situation and response (Peter M. Gollwitzer, 1999).

Example

“When I open a new topic on Monday morning, I first write down its guiding question” is an implementation intention; “I want to work more thoroughly” is a goal intention.

How it applies

  • The concept: Gollwitzer (1999) distinguished goal intentions (“I intend to reach Z”) from implementation intentions, which specify when, where and how to act. The if-part makes the situation easier to notice; the then-part makes the response more automatic once the situation arises.
  • The evidence: A meta-analysis by Gollwitzer and Paschal Sheeran (2006) of 94 independent tests found a medium-to-large effect of implementation intentions on reaching goals.
  • Working method: Writing the first step of a routine as an if–then plan ties it to a fixed situation; repetition in that situation can then build a habit.

Implementation intention vs. habit

An implementation intention is a deliberate plan that delegates the start of an action to a situation. A habit is the result of repetition, in which the situation triggers the action without a plan. The first can lead to the second.

How to read this pool

Entries, context cards and transitional topics

The art of thinking explains ways of thinking — where a method comes from, what it asks of you and how it was adapted later. You meet four kinds of content here, each with its own job:

Glossary entry
Defines one concept or method of thinking: its origin, an example and how it relates to neighboring ideas. “X vs. Y” sections set two methods side by side.
Context card of the art of thinking
A short, self-contained answer to one question about a way of thinking — its lineage, its steps, its limits. These cards are listed on The art of thinking only.
Transitional topicBridges both pools
A context card that bridges both pools: it shows how a way of thinking was adapted into documentation, analysis or quality practice. It sits with the reference context cards and is marked as transitional wherever it appears.
Reference entry or context card
Belongs to the Glossary & Norms Space on regulation, norms and engineering. Entries here link to one only where a method is also an established tool of documentation or quality work, such as the five whys or a user’s mental model.

Definitions follow the cited philosophical and historical sources — primary texts, their standard translations and reference works such as the Stanford Encyclopedia of Philosophy — and, for cognitive psychology, the published research and its reviews, with the state of the evidence named in each entry. They are paraphrased, not quoted, unless a passage is marked as a quotation, and sayings that cannot be traced to a source stay attributed. Examples, comparisons and the notes on how a method was adapted are editorial commentary by knowledge.aitechdoc.world. None of these entries is a norm, a standard or a legal requirement, and applying one never replaces a method that a standard or a law requires.
