Curiosity Gap
Also known as Information gap theory
When people notice a gap between what they know and what they want to know, curiosity motivates them to close it.
See it in action
The same screen without and with Curiosity Gap. Watch both sides play out, then compare the outcome.
A generic statement closes the loop before it opens; there's no reason to tap.
A concrete hint at something people want to know invites the tap — and the report delivers it.
What to watch: the same report; only the gap between what's shown and what's promised changes.
Tease specific, relevant information and always pay it off on the next screen.
Use clickbait that over-promises; broken curiosity gaps destroy trust fast.
Key takeaways
- Teasing valuable information motivates users to take the next step.
- The gap must feel small enough to close and worth closing.
- Always deliver on the promise; clickbait destroys trust.

Curiosity Gap explained
Curiosity is triggered when people become aware of something they do not know but would like to. The gap creates tension that motivates action to resolve it.
The effect is strongest when people already know a little about the topic and the missing piece feels attainable.
In products, curiosity gaps can draw users into onboarding, encourage exploration and highlight value, but only if the reward lives up to the promise.
Where it comes from
Economist and psychologist George Loewenstein proposed the information gap theory of curiosity in 1994. He argued that curiosity arises when attention is drawn to a gap in knowledge, producing a feeling of deprivation that people want to resolve.
How it shows up in apps
Previews, teasers, progress reveals and personalised insights create curiosity gaps that encourage sign-up, engagement and exploration.
Curiosity Gap examples
A personality quiz app shows users a partial result ('You are one of three types...') and invites them to answer two more questions to reveal their full profile. Completion rises because the gap feels small and worth closing.
Personalised insights
Apps that tease a personalised insight before sign-up ('See how your spending compares') motivate users to create an account.
Locked previews
Content platforms show the beginning of an article or video and invite users to continue, drawing them into the full experience.
Feature teasers
Products hint at what users can unlock next, encouraging them to explore deeper features.
How to apply Curiosity Gap
- Reveal part of a valuable outcome to motivate the next step.
- Keep the gap small and the next step easy.
- Make sure the payoff is genuinely valuable.
- Use curiosity to guide users toward meaningful features.
- Avoid misleading headlines and teasers.

Common mistakes
- Clickbait that fails to deliver, eroding trust.
- Creating gaps that require too much effort to close.
- Hiding essential information behind teasers.
How to measure it
Measure click-through and completion rates for teaser-based steps, and track satisfaction and retention to make sure curiosity leads to value rather than disappointment.

Motivation & emotionZeigarnik Effect
People remember unfinished or interrupted tasks better than completed ones, and feel a pull to return and complete them.
Motivation & emotionVariable Reward
Rewards that come unpredictably are more engaging than predictable ones, because anticipation of what might come next keeps people returning.
Motivation & emotionGoal-Gradient Effect
People speed up their effort as they get closer to a goal, so visible progress — even artificial head starts — increases completion.
