Why can a tiny quiz question feel more magnetic than a polished mini-lesson?
Show answer & explanation
Answer: A visible knowledge gap
A visible knowledge gap ✓ — Right. Loewenstein's information-gap idea says curiosity grows when attention lands on a specific gap between what you know and what you want to know. A good quiz stem makes that gap visible before giving relief. The surprise is that the missing piece can be more motivating than the explanation itself.
Shorter screen time — Shortness helps only when it creates a handle for attention. A short clip with no gap can still slide past like any other feed item. The useful compression is not just fewer seconds; it is a sharply framed missing piece. That is why a 10-second question can feel bigger than its length.
Interactive feeling — Interactivity helps when it makes the learner do real mental work, but clicking alone is not the engine. A poll with no knowledge gap can feel busy without becoming memorable. The quiz works when interaction exposes a specific missing piece. The button is the wrapper; the gap is the pull.
