Spreading Links
Two words trigger memories, bodily reactions, causal expectations, and avoidance.
Coherent Fiction

Priming Without Awareness

Invisible Influences
Behavioral Shifts
The Florida effect experiment links elderly-themed words with slower walking.
Threat to Agency
The research unsettles the belief that conscious intention authors every action.
Cognitive Ease

Ease as Evidence
Fluency
Clear fonts, repetition, mood, and familiarity make ideas feel true.

People often mistake the source of ease, confusing fluency with truth, safety, or credibility.
The Unturnoffable System

Automaticity and Vigilance
Persistent Suggestions
System 1 keeps generating impressions even when deliberate thought is preferred.
