Affirming a disjunct is a form of logical fallacy where an alternative possibility is rejected because the first is accepted, even if both are accurate. The problem with this fallacy is typically an underlying misunderstanding that establishes a false dichotomy.

Formal Construction

  • A or B
  • A
  • Therefore, it's not B
