Intention–action gap: describe the missing step without guessing a motive
Gollwitzer and Sheeran distinguish forming a goal intention from attaining that goal in their chapter on implementation intentions. [1]
General education and practical perspectives. Editorial standards.
An intention–action gap names the space between what someone intended and what happened. We use that wording to open a practical question, not to announce that we know why a person delayed, changed direction or could not proceed.
A message that was never sent
In an invented example, Riley intends to send a photograph of a repaired lampshade to a relative on Saturday. On Monday, the photograph is still unsent.
Several different things could fit that short description. Riley may not have taken the photograph, may have waited for better light, may have lost the message draft or may have decided not to share it. The observer's knowledge is limited to the unsent message.
Asking “Which part did you still want to do?” is different from declaring “You did not care enough.” Riley might also say the plan is no longer wanted. A canceled intention does not have to be turned into a new obligation to close a tracking box.
Separate the pieces
If you want to look at your own unfinished plan, try a short sequence:
- What I intended, in my own words.
- What I actually did, if anything.
- What remains unknown or unavailable.
- Whether I still want this outcome.
- A next step I choose, or a decision to stop.
- Any request another person has agreed to consider.
For Riley, the next step might be finding the photo already taken. It might instead be telling the relative that no picture will be sent. Neither response establishes a general explanation for anybody else's unfinished plans.
Do not confuse description with cause
The gap is the thing being described. It is not a diagnosis or a complete explanation. If a post attributes all gaps to one psychological process, that additional assertion needs its own evidence; the vocabulary alone does not supply it.
A partner might see the uncompleted outcome while an adult sees several unrecognized steps already attempted. A child might have understood a request differently from the parent who made it. A sibling may need an update, not a detailed explanation of someone else's internal experience.
A small conversation is enough
You can discuss one plan without auditing every unfinished task in the household. Keep the person's current intention visible and avoid assigning another relative the permanent role of checking compliance.
This page does not offer a treatment method, decide whether a promise creates a legal obligation or explain ADHD through a single planning difficulty. Its practical purpose is to distinguish intended outcome, observed action and unanswered questions so the next conversation starts from what is actually known.
