We've all heard some form of the following statements:

  • "I like cookies, therefore everyone likes cookies"
  • "That plane is yellow, so all planes must be yellow."
  • "I have come to this conclusion, and if I have, then everyone else must have too"

The logical fallacy in these statements is: A is B, so everything is B.

Is there a name for this type of fallacy?

  • This is the A is everything fallacy.
