What it looks like
You have the time. You know roughly what needs doing. You open the list, read it, close it, and do something else — usually something small and unimportant that provides the sensation of progress.
It is distinct from procrastination, where a specific known task is being avoided. In paralysis the task hasn't been selected yet.
The main causes
Too many equal-weight options. When nothing is clearly first, choosing means risking choosing wrong.
Vague items. "Sort out the tax" has no first physical action, so there is nothing to begin.
Unresolved open loops. Masicampo & Baumeister (2011) found unfinished goals intrude on attention until a specific plan exists — so a long unranked list generates continuous background pull.
Consequences that feel large. When the stakes feel high, deferring feels safer than acting.
What actually breaks it
Externalise everything first — a partly-in-your-head list can't be triaged.
Impose one order using a single rule, so the comparison step disappears.
Name the first physical action for the top item only, small enough to be almost trivially startable.
Hide the rest. Visibility of the full list restores the choice you just removed.
A note on the willpower explanation
Task paralysis is often attributed to decision fatigue. That model is contested — Hagger et al. (2016) found the ego-depletion effect indistinguishable from zero across 23 labs. Cognitive load and unresolved goals explain the same experience with better support. Detail at is decision fatigue real?

Frequently asked questions
Is task paralysis a medical condition?
No. It's a descriptive term for a common experience, not a diagnosis. It's reported more often by people with ADHD, anxiety and depression, but it happens to plenty of people with none of those.
How is it different from procrastination?
Procrastination is avoiding a task you've already identified. Paralysis is being unable to identify which task to do. Motivation advice targets the first and misses the second.
How long does it last?
It usually breaks the moment the choice narrows to one concrete action. If it persists across weeks and comes with low mood or loss of interest, that's worth discussing with a professional rather than treating as a productivity problem.
