> LEM is simply taught as the truth in university courses.

So is[0] the notion that quantum systems magically undergo non-local, non-linear, non-unitary, CPT-violating, Liouville's-Theorem-violating, non-deterministic evolutions whenever a macroscopic system that happens to implement a sapient intellegence looks at something[1]. So that's not a very good yardstick for "this is not obviously false".

0: sample size of one univerity (circa 2010) for "simply taught as the truth", but I think it's recent enough and widespread enough to make a good example. See [2] if you want to investigate further.
