Why saying your cereal is asbestos-free makes people think it might be dangerous.

The Hidden Rules of Conversation · 5:33 · Video: Tom Scott · Watch at the source

In short: We follow unspoken guidelines in every conversation that shape how we interpret meaning. Understanding these Gricean maxims explains why certain phrasing feels suspicious even when the literal words are technically true.

In 1975, philosopher H.P. Grice introduced a set of principles in his work 'Logic and Conversation' that govern how humans communicate. These guidelines are not strict laws but implicit expectations we rely on to make sense of one another.

When someone describes cereal as 'asbestos-free,' it triggers suspicion because it violates the expected cooperative nature of conversation. By providing unnecessary information, the speaker implies that the presence of asbestos is a relevant concern, even if it is not. Recognizing these hidden rules helps clarify how context and implication override literal definitions in daily interaction.
