archeology

This is a pet peeve of mine: Scientific terms ("ritual" in this case) that also are commonly used in everyday language, but have a slightly-to-massively different meaning between the two worlds.

This "ritual" vs. "ritual" is a harmless example (that only annoy archeologists, which is fair, because they are overusing this even if you understand it as scientific term) but if you watch (early) Jordan fucking Peterson talks, he does this extensively; using Psychology-specific scientific terms that are misunderstood by the public, and he and his crowd are both too stupd to notice. (nowadays, he is just spewing insane bullshit, so, no more confusion there)
