Why do I get stuck on one question?
You tell yourself "just one more try" and look up to find five minutes gone. Getting stuck isn't a lack of ability; it's a predictable pattern in how we allocate effort.
The cost is the items you never reach
People get stuck on one question because of sunk-cost thinking (not wanting to waste effort already spent), mental set (repeating the same approach), a belief that persistence always pays off, or anxiety about leaving something unfinished. In timed tests, this can cost more points than the difficult item is worth. A time limit per item and a flag-and-return habit prevent it.
Why we stay stuck
| Reason | Inner voice | Better response |
|---|---|---|
| Sunk cost | "I've already spent so long" | Past time is gone; decide based on remaining time |
| Mental set | "This approach should work" | Try a different feature |
| Near-solution feeling | "I'm almost there" | Set a 30-second last attempt |
| Perfectionism | "I can't leave it unanswered" | Guess, flag and return |
| Curiosity | "I need to know" | Save it for after the test |
"Almost there" is unreliable
The feeling of being close to a solution is often unreliable. People can feel "almost there" while pursuing an incorrect representation of the problem. Meanwhile, time limits mean every extra minute on one item reduces time for others. Research on speeded testing highlights how timing shapes scores, so time allocation is a real part of performance.
How this looks in practice
With 30 items in 20 minutes, a test taker spends five minutes on item 9 and doesn't reach the final six items. If she had flagged item 9 after 80 seconds, she likely would have answered several of the remaining questions correctly.
A move-on rule
- Know your average time per item.
- If you reach double that, make a best guess and flag the item.
- Return only after completing the rest.
Stuck question questions
How long should I spend on one IQ question?+−
Use total time divided by number of items as a guide, and move on at about double that.
Why is it so hard to move on from a question?+−
Sunk-cost thinking makes it feel wasteful to abandon effort already spent.
Should I always skip hard questions?+−
In timed tests, skip and return; in untimed tests, persistence may be fine.
What if I can't go back to skipped questions?+−
Eliminate options, make your best guess and move on.
