According to Wikipedia "*mathematical realism is the view that mathematical
truths are objective and exist independently of the human mind*". I then
asked the AI Claude and it said something very similar but added that
mathematical realists believe *"Mathematical statements are objectively
true or false. For example, the statement 2 + 2 = 4 is always true,
independent of what any human believes about it*." So you *DO* have to
be a mathematical
realist to believe that adding one apple to another apple in a bowl gives
you two apples.

You've made the same accusation before and I gave a detailed response as to
why I think you are incorrect and why Many Worlds give a better
understanding of why the Born rule is what it is than any other quantum
interpretation. You didn't specifically refute anything I said, you just
waved your hands around and said I was wrong.
