They have a name for it!!

There is a scientific name for that thing where idiots and ignorants, despite knowing practically nothing about what they are talking about, actually attempt to tell you something contradictory to your own knowledge, as if they had some sort of leg to stand on!

Next time someone someone starts in on some half-baked idiot-theory, just calmly and politely suggest they are suffering from the Dunning-Kruger effect, and quickly change the subject.

This also explains why so many religious people, with no scientific training whatsoever, feel so comfortable dismissing the collected work of some of the smartest minds of our time in order to prop up their flimsy faith in magic books. It also explains how a quick search of the internet can find people who can barely manage the English language to a coherent degree, yet have figured out the all the answers to the most perplexing mysteries of the universe, like time travel and limitless energy sources.

Silly scientists, you don't need an education, rigorous research methods, peer review, or ridiculously expensive instruments! It all becomes much more simple when you just do away with all those things.
