Introspection and Its Limits
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Introspection is a trained report of one's own conscious experience, and it cannot be checked by a second observer.
Show
Two trained observers in Wundt's laboratory describe the same tone differently, and no third measurement settles which report is right.
Watch for
Unverifiable is not the same as false. Introspection failed as a method, not as a phenomenon.
