Except even scientists will often use "hypothesis" and "theory" interchangeably. For example Stephen Jay Gould's theory on punctuated equilibrium, kin selection (theory) vs group selection (theory), all the various names given to Williams/Dawkins/Ridley's theories on evolution, all the various theories relating ontogeny to phylogeny, and on and on. All these things are probably more properly referred to as hypotheses within the broader theory of evolution, where here the meaning of theory switches to be more in line with the "true" definition of theory. But maybe this is just an idiosyncrasy of evolutionary biologists, I'm not familiar enough with other fields. But then again there are all of those mathematical "theories" like group theory, number theory, set theory, game theory, and on and on. Not sure how to categorize these. Point is we (scientists/scientific communicators) often make this hardline distinction between the meaning of "theory" and "hypothesis" but regularly break our own rule.
