Episode notes
Fractionated Perception Shapes Belief
- Humans mentally 'fractionate' the world, and that process distorts perception at many levels.
- Instruments and publication processes also fractionate what we observe and share.
Marketing Fail From Fraction Confusion
- A&W launched a third-pound burger that failed because many consumers thought one-third was smaller than one-quarter.
- The campaign showed intuitive fraction misunderstandings can wreck otherwise logical marketing.
Redefining Sets To Save Beliefs
- The No True Scotsman fallacy redefines group membership to protect beliefs instead of revising them.
- This maneuver alters the denominator and corrupts honest evaluation of evidence.
