    2+2 is a fact

    In some sense, if every single human thought that 2+2 equaled 5, it would become true

    (I’m not smart enough to come up with this lol, got it from Orwell’s 1984)

      Only if you completely redefine some aspect of the equation. You’d have to define “5” to actually mean “4” or change the meaning of “+” or “=” in some way that changes the operation. 2+2=4 isn’t just an abstract statement, it’s based on the way the physical world works. If you have 2 apples, and then I give you 2 more, you don’t suddenly have 5 apples because we all decided 2+2=5.

      Orwell’s meaning in 1984 wasn’t about belief changing the world, it was about the power of brainwashing and how fascism demands obedience.

      It doesn’t even require belief.

      2+2=5 for sufficiently large values of 2.

      While a facetious statement in general, it is factual if those values derive from rounding. Significant Digits must be maintained.
