Mental Contrasting vs To-Do Lists
Published .
A to-do list tells you what to do. Mental contrasting asks what is in the way. Here is when each one helps, and how to fit both on one page.
Mental contrasting is a short thinking exercise from the psychologist Gabriele Oettingen: you picture the best outcome of a goal, then picture the main obstacle inside you that stands in the way. A to-do list is a list of tasks you mean to do. The list holds the work. Mental contrasting checks whether you are committed to the goal behind it, and what is most likely to stop you.
The short answer
Keep a to-do list for the many small things a day holds. Use mental contrasting for the few goals that matter, before you add their tasks to the list. Then give the top task a when and a where. The list on its own collects open loops. The research below suggests that a goal you have contrasted and a task with a specific plan tend to get more follow through.
Side by side
| Question | To-do list | Mental contrasting |
|---|---|---|
| What it is | A list of tasks | A few minutes of thinking about one goal |
| What you write | Things to do | The best outcome, then the main inner obstacle |
| Obstacles | Not part of it | The center of it |
| When and where | Usually missing | Added in the if-then plan (WOOP) |
| Best for | Catching everything so you can stop holding it in your head | Deciding whether a goal is worth it and what will get in the way |
| Main risk | A long list that never shrinks | Thinking about the goal without a next step |
What the research says, carefully
- Mental contrasting. In four experiments, Gabriele Oettingen, Hyeon-ju Pak and Karoline Schnetter (2001) compared people who contrasted a wished-for future with the reality in the way, people who only imagined the future, and people who only thought about the present problems. After contrasting, commitment followed expectations: people who thought success was likely committed more strongly, and people who thought it unlikely committed less. In the other two groups commitment was moderate whatever their expectations (source).
- If-then plans. Peter Gollwitzer and Paschal Sheeran (2006) pooled 94 independent tests of implementation intentions, plans of the form "if this situation, then I will do that". They reported a positive effect on goal attainment of medium to large size (source).
- The two together. A 2021 meta-analysis by Guoxia Wang, Yi Wang and Xiaosong Gai looked at mental contrasting with implementation intentions (MCII, the method behind WOOP) across 21 studies and 15,907 people. It found a small to medium effect on goal attainment, and the authors note possible publication bias, so the true effect may be smaller (source).
- Unfinished goals and plans. In studies published in 2011, E. J. Masicampo and Roy Baumeister found that unfinished goals tended to intrude on people's thoughts and get in the way of other tasks, and that making a specific plan for the goal reduced those effects, even before any of the plan was carried out (source). A task on a list is not yet a plan. Adding when, where and how is what made the difference in these studies.
Most of this work comes from lab tasks and short studies, and results vary by person and setting. Treat it as a guide, not a promise. These are planning habits, not therapy or medical advice.
When a to-do list is enough
- The tasks are small and clear, like errands, replies and bookings.
- You already know you want the result, and nothing much is in the way.
- You mostly need to get things out of your head so you can stop holding them.
When to add mental contrasting
- The same task has moved from list to list for weeks.
- The goal is big, new or uncertain, and you are not sure you want it enough.
- You know the work, but something inside you keeps getting in the way: a habit, a feeling or a thought.
The WOOP method page walks through the four steps, and implementation intentions shows how to write a strong if-then plan.
How to use both with reverse journaling
- Write the goal as done. Past tense, with a date. This is the outcome you picture, written down.
- Name the obstacle. The one thing inside you most likely to stop it. This is the contrasting step.
- Write the if-then plan. "If that happens, then I will..." One line.
- Plan backward to today. Step back from the finish line until you reach something that fits in about 45 minutes. Backward planning shows the method.
- Put that one step on your to-do list, with a time. The rest of the list stays as it is.
- Log it tonight. One line on what you did. Tomorrow's step comes from that line.
Example: from list item to plan
Maya's to-do list has carried "update CV" for five weeks. Her goal is a new job in product design.
- Goal written as done: "On 31 March I accepted an offer for a product design role."
- Best outcome: "Work I care about, with a team I learn from."
- Inner obstacle: "I open the CV, decide it is not good enough to start, and close it."
- If-then plan: "If I think the CV is not good enough, then I will write a rough version of one section and stop there."
- Today's 45 minutes, on the list with a time: "7 pm: rough draft of the top section of the CV."
- Tonight's log: "Drafted the top section. Need numbers for the last project."
The list item did not change much. What changed is that it now has a reason, a named obstacle, a plan for that obstacle and a time.
Where this fits in Reverse Journaling
Reverse Journaling builds mental contrasting into the first page: the goal written as done is the outcome, and the obstacle with its if-then plan comes right after. The backward plan then turns it into one task for today, which is the part a to-do list is good at holding. The done list covers the nightly log.
Try it now
Find the oldest item on your to-do list. Write the goal it serves as done, name the inner obstacle, write one if-then line, and give the task a time today. That is all mental contrasting asks for, and it takes about five minutes.
Questions
What is the difference between mental contrasting and a to-do list?
A to-do list holds tasks you mean to do. Mental contrasting is a short exercise where you picture the best outcome of a goal and then the main inner obstacle in its way. The list holds the work, and mental contrasting checks the commitment and the obstacle behind it.
Who created mental contrasting?
The psychologist Gabriele Oettingen. Her research with colleagues, including a 2001 paper with Hyeon-ju Pak and Karoline Schnetter, found that contrasting a wished-for future with the obstacles in the way tied people's commitment to how likely they thought success was.
Does mental contrasting work better than a to-do list?
They do different jobs, and no study has tested one against the other directly. Research on mental contrasting with if-then plans found a small to medium effect on goal attainment, and research on plan making found that a specific plan helped an unfinished goal stop crowding people's thoughts. Results vary, so treat it as a helpful habit, not a guarantee.
What is WOOP?
WOOP stands for Wish, Outcome, Obstacle, Plan. It is the everyday form of mental contrasting with implementation intentions: you name a wish, picture the best outcome, find the main inner obstacle, and write an if-then plan for it.
Can I use mental contrasting with my to-do list?
Yes. Before a big goal goes on the list, write the outcome and the inner obstacle, then an if-then plan. Put only today's first step on the list, with a time. The rest of the list can stay as it is.
