Put two theories under the same test

Enter your own wording. Nothing is submitted, saved or published, and the Casebook does not pre-fill unverified claims.

Evidence rule: the same standard applies to both columns. A theory should identify supporting evidence, conflicting evidence, assumptions and a test that could prove it wrong.

Theory A

Theory B

Final comparison check

  • Have both theories been tested against the same spoiler boundary?
  • Does either theory depend on absence of evidence as if it were positive proof?
  • Is a confirmed fact being confused with a character’s belief or a viewer inference?
  • Could one new piece of evidence clearly change the ranking?

Publication boundary

A worksheet is not an endorsement

The tool supports comparison before a theory reaches the public board. It does not make a claim approved, sourced or true.
