Task paralysis: why starting is hard and what's been tested

“Task paralysis” describes wanting to start something and not being able to. You will not find it in a diagnostic manual, and procrastination is not an official ADHD symptom either ¹. What studies do show is a consistent link between ADHD symptoms and procrastination, with inattention as the strongest factor ².

What the evidence says

A systematic review of 11 studies covering 2,788 people found that ADHD symptoms were consistently associated with procrastination ².

Several explanations have support:

• Later rewards count for less. In a meta-analysis, people with ADHD discounted delayed rewards more steeply than comparison groups ³.
• The task itself feels low in value. In a survey of 640 adults, the link between inattention and procrastination ran through sensitivity to delay and seeing the task as having little value ⁴.
• The intention gets lost. In a small study of 29 adults with ADHD and 24 without, those with ADHD remembered and carried out fewer of their own everyday intentions, and this explained part of the link between symptoms and procrastination ⁵.

In one meta-analysis of studies that were not specific to ADHD, strong and consistent predictors of procrastination included disliking the task, delay, low confidence in being able to do it, and impulsiveness ⁶.

What we don’t know

Most of these studies are surveys taken at one point in time. They show that things go together, not which causes which.

Reminders are a good example of how little is settled. In a trial with 109 adults who reported an ADHD diagnosis, text reminders may have led people to log in to an online self-help programme sooner, but did not raise the rate at which they finished its modules ⁷.

Tactics are not the whole picture. In a randomised trial of 88 adults with ADHD, a 12-week therapist-led programme teaching time management, organisation and planning had a higher response rate than supportive therapy ⁸.

Things to try

These findings are from general-population studies, not ADHD trials.

• Start with small steps. In an eight-day study of paid crowdsourcing workers, a plan that set small sub-goals for the first four days and the full goal after that had the highest rate of reaching the goal, at 57.1% ⁹.
• Build in slack. Giving people a few “emergency” skips meant they met a step-count goal on up to 40% more days a week ¹⁰.
• Plan the comeback, not the streak. In a study of more than 60,000 gym members, the most effective of 54 approaches was a small reward for returning after a missed workout ¹¹.
• An interrupted task tends to get picked up again. Across studies, people went back to an interrupted task about two times in three ¹².
