Episode notes
Random Chopra‑Style Sentences Test Receptivity
- Pennycook used randomly generated Deepak Chopra–style sentences to test receptivity to pseudo‑profound statements.
- People who rely on gut feelings judged both real and random statements as equally profound.
Two Modes Of Thought Matter Online
- Thinking has two modes: fast intuitive responses and effortful deliberation.
- Overreliance on intuition makes people vulnerable to nonsense online.
Nudge For Accuracy Before Sharing
- Prompt people to consider accuracy before they share content to reduce spreading falsehoods.
- Small nudges (ads/questions) increase reflective checks and cut reflexive sharing.
