"Taking the black pill" names a posture of fatalism that migrated from fringe men's forums into the wider internet. The metaphor riffs on the pills in The Matrix, but where the "red pill" claims to reveal hard truths, the black pill says those truths are terminal and change is pointless. In its most specific and consequential register, it is tied to the incel subculture that coalesced online in the early 2010s. Encyclopædia Britannica traces the phrase's popularization to the incel blog Omega Virgin Revolt and records a further radicalization after May 23, 2014, when some forum users glorified Elliot Rodger's Isla Vista murders with talk of "going ER," a dark shorthand for destruction and loss of hope.
