They basically stopped short of calling the scientific method a cultural construct, at which point I'm sure I would have snapped.

I can't resist...

Did scientific method grow on a tree, or did people invent it?

Did people invent scientific method simultaneously everywhere, or was it invented and practiced at specific places?

:D

The real fallacy in my opinion is having a connotation that if something is constructed and promoted within a culture, that makes it wrong. For example, consider the Pythagorean theorem... knowing that Pythagoras was a rich white cis male, shouldn't we remove it from the curriculum? And perhaps replace it with something more enlightened, such as: "all sides of a triangle are equal, even if their lengths may be different".

In the same sense, science, even rationality itself, are cultural constructs. Maybe even human speech is a cultural construct, but luckily that happened sufficiently long ago so now all cultures have it. Okay, I am not sure about the last example. But I am sure that calling things "cultural constructs" is a cultural construct itself.
