Last Thursdayism
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
This theory posits that the universe was created just last Thursday, but with implanted traces of being billions of years old (including your memories). It is a logically unfalsifiable but meaningless hypothesis.
SCAFFOLDING EFFECT
Reduce cognitive load
A touchstone for Occam's Razor. Although unfalsifiable, it introduces immense complexity (why fake history?). When facing conspiracy theories, use this principle: if a theory requires extremely complex assumptions to explain simple facts, even if logically consistent, it should be discarded.
Anchor fast decisions
A parody of philosophical skepticism (Last Thursdayism): it asserts that the universe, along with your memories and fossil evidence, was created 'last Thursday', so any counter-evidence is seen as 'implanted'. The mechanism is to use an unfalsifiable extreme hypothesis to reveal problems in certain theories.
