To me, these three aren't separate categories—they sit along a single spectrum.
Take ancient knowledge: it's centuries of lived experience boiled down, yet it often carries superstition and bias along with it. Because it lacks a logical framework and rigorous methods for testing what's true, it's hard to know how much weight any particular piece deserves, even if plenty of it may be useful.
Science, by contrast, is simply logic and systematic method turned toward discovering truth. Its limitation is capacity—it can't cover everything. And by design, it avoids subjects where rigorous methods can't be applied. So many things remain unexamined, even when there might be something worthwhile there.
As for biohacking, that's essentially science done by amateurs. It brings modern information to bear, but without the rigor or precision—because, whether we like it or not, we aren't trained the way scientists are, and we lack their resources. So we lean on partial knowledge, gut feeling, hearsay, and trial-and-error. That said, it isn't worthless. Over time, the collective experience of many people does get refined into things that work. Still, it will never match the reliability of the scientific method.
