A midwit, or someone or middling intellect, who gets caught up in some form of mass
hysteria.
Strong supporters of a nanny state mentality to the
point of insanity, and excellent examples of the Dunning Kruger effect in action. Named after the John Wyndham novel "the Midwich Cuckoos".
"Look at these midwit cuckoos, they want all
dogs put down because some child
got bitten by one recently."
"This
guy says all humans must be exterminated to save the planet. What a midwit cuckoo."
