Retreat Phrases Let People Back Out Of Escalation
- In a sexual come-on or boss-employee scenario someone can say "I didn't mean it that way" to retreat.
- Pinker notes that the retreat is available even if not entirely plausible, keeping the relationship intact.
Uncertainty Maintains Social Roles
- Social signals fail when participants can't be sure others know the signaler knows they know it.
- Pinker uses examples like sexual come-ons and boss-employee interactions to show how uncertainty maintains platonic or hierarchical roles.
Euphemisms Preserve Plausible Deniability Of Common Knowledge
- Euphemisms preserve plausible deniability not of intent but of common knowledge.
- Steven Pinker explains that vague language lets participants avoid acknowledging that everyone knows that everyone knows, thus preserving relationship norms.
