The bell curve of conspiracy theories strikes again! On both ends of the IQ spectrum (the 0.1% geniuses and the, um, less academically gifted folks), people believe contrails are chemtrails. Meanwhile, the enlightened middle 34% understands they're just water vapor condensation from aircraft exhaust.
What we're seeing is the horseshoe theory of intelligence in action - where the extremely smart and extremely... not smart... somehow reach the same wrong conclusion while the average Joes get it right. The frantic sweaty guy at the top is having an existential crisis trying to explain science to both ends!
