Curiosity Spike Hook — Examples, Psychology & Scaling Data
A Curiosity Spike is an opening hook that creates an information gap the viewer's brain feels compelled to close. It's built on George Loewenstein's information-gap theory of curiosity: when someone senses a specific piece of missing knowledge, their working memory allocates attention to resolving it, even if the topic has no prior relevance to them. In video ads, this shows up as a partial reveal, a teased secret, or a counterintuitive claim that demands clarification. The viewer doesn't scroll because scrolling means leaving the gap unresolved — and the brain processes unresolved gaps as low-grade psychological tension.

The Psychology Behind the Hook
Mechanism: Information Gap Effect
A Curiosity Spike is an opening hook that creates an information gap the viewer's brain feels compelled to close. It's built on George Loewenstein's information-gap theory of curiosity: when someone senses a specific piece of missing knowledge, their working memory allocates attention to resolving it, even if the topic has no prior relevance to them. In video ads, this shows up as a partial reveal, a teased secret, or a counterintuitive claim that demands clarification. The viewer doesn't scroll because scrolling means leaving the gap unresolved — and the brain processes unresolved gaps as low-grade psychological tension.
The reason Curiosity Spike hooks outperform generic openings is that information gap effect is processed involuntarily. The viewer's brain cannot opt out — the response fires before conscious attention decides whether to engage. That pre-conscious hook is what buys the 2-5 second window the rest of the ad needs to make its case.
