Debunk

Debunkers are scientific skeptics who actively attempt to disprove and pursue what they consider to be false, unscientific, bizarre or abnormal claims. [1] The ultimate intent of the debunking, according to some, is conclusively to disprove the validity of an event, theory, and/or phenomenon by exposing it as nonsense. According to Wiktionary, debunk means To discredit, or expose to ridicule the falsehood or the exaggerated claims of something.
