Elf Told in 8-Bit In 120 Seconds

Funny, he starts by mentioning how complex things don't always fit neatly within our brain, but then goes on to try to make clear-cut boundaries between the terms. Unfortunately science isn't that easy to pigeonhole, and scientists as a result don't use the terminology that neatly. You can occasionally find cases where something is called both a law or theory depending on the author. The boundary between hypothesis and theory is not as simple when the hypothesis is built upon well tested regimes of previous theories, so the new idea effectively matches past tests of the theory it extended. Observations often depend on other theories and assumptions.

Anyway, I think trying to ascribe specific definitions to those words often misses the important points. Inductive logic never results in absolute truths, as you never test every possibility. Statements in science, like most things, just come in a giant spectrum of confidence. That confidence shifts with each new observation, prediction and competing idea, but it rarely jumps discretely from one category/label to another.

Unfortunately, having some sense of where a theory falls on the confidence spectrum usually involves learning some of its history, what observations it is based on, and what alternatives are being pursued. That takes a lot more effort than just looking at its name.

Anyway, I don't mean to be negative about the video, as it is still roughly how those words are used. But it reminds me of oversimplifications that were in primary school textbooks, which do a good job of teaching the gist of a topic, but sometimes can be counterproductive when the person stumbles over a more complex case.
