Isn't part of the point of science as a concept to mitigate this kind of thing? Like since we can't know each others' subjective experience, we agree on external, relative variables to measure with instead?

Wavelengths of light have already been mentioned, but the same applies to things like distance and time. Lots of things (like drugs, precious drugs) mess with your experience of time, so we make clocks to measure time in an external fashion so that we can have an agreed upon standard, right?

Your inner experience is often a short-sighted idiot and needs correction from group consensus and NO you cannot reject this truth because of capitalism, you just gotta learn how to read graphs n shit

EDIT: don't take this post too seriously I'm a zoology enjoyer not a philosopher
