No True Scotsman

The no true Scotsman fallacy appeals to the "purity" of an ideal or standard as a way to dismiss relevant criticisms or flaws in your argument.

Example of No True Scotsman

  • John doesn't drink alcohol. No real man avoids alcohol. John isn't a real man. The argument creates an ideal man, and uses it to prove a point.
  • Sarah always wears slacks. No real woman would wear slacks. Sarah is not a real woman. 'Establishing' that no real woman would wear slacks creates the fallacy.

This is a common fallacy.
