Summary
Denialism is the rejection of well-established facts and concepts, whether scientific, historical, or psychological, in favor of controversial or fabricated ideas. In scientific and historical contexts, it involves dismissing overwhelming evidence and attempting to create political controversy to deny a consensus, exemplified by Holocaust denial, AIDS denialism, and climate change denial. Psychologically, it is an irrational behavior where individuals deny reality to avoid uncomfortable truths, serving as a defense mechanism against cognitive dissonance. Motivations for denialism can include religion, self-interest (economic, political, or financial), and psychological defense mechanisms. A recent prominent example involves Sheryl Sandberg's expression of shock and disappointment over the widespread denialism of systematic sexual violence used by Hamas during the October 7th attacks in Israel, which she links to extreme political polarization, rising anti-Semitism, and a perceived silence from some feminist movements.
