The Y2K Effect

A social phenomenon that occurs when experts work diligently to avert a crisis, only for the general public to deem the potential crisis a hoax should the contingency efforts be successful. Named after the aversion of the Y2K bug, which has been largely deemed a hoax over the past couple of decades because it never actually occurred thanks to programmers behind the scenes preparing the new millennium of technology for the 21st century.

"Hey remember that rumor the bridge would collapse? I can't believe they actually tried to scare us like that"
"The bridge legitimately was at risk of collapsing, but construction teams examined the issue right away and made necessary repairs to avoid the disaster"
"Woah, really?"
"Yep, The Y2K Effect struck again"
