The cargo-cult phenomenon dates from before the internet, but the internet (and certain historically recent social changes, too, I think) create an echo chamber of massive proportions that changes the nature of the phenomenon. In this environment, it becomes much more difficult to insulate yourself from cargo-cult thinking, and much more difficult to tolerate opposing opinions.
