It's even stronger, in that mathematics generalized arithmetic algebra into groups, fields, rings and other things I don't understand. Examples of specific algebras include: boolean, relational and Kleene (aka regular expressions).
Other notations are used, but with a frequency similar to pre-fix (lisp) and post-fix (forth). "Associativity" (not affected by order of evaluation) only makes sense for in-fix.
But it really could just be familiarity, I guess. I can't see how to determine it either way. But regardless of the cause, there's overwhelming evidence that people, in fact, prefer in-fix.
