Thanks for bringing this up for the people who aren't familiar with the history of the term. In my opinion, "cargo cult" is overused and overly specific. We have a perfectly good word for these kinds of behaviors, i.e. "superstition"
Yeah, superstition works most of the time. Though the things that cargo-culters do usually make sense given the right context. Many superstitions (black cats, ladders, lucky socks, and unlucky numbers) have no rationality in any situation.
