The persistent myth trace back to the early days of personal computing and early internet chain letters. According to widely accepted digital folklore, columnist Lisa Holst penned an article in a 1993 issue of PC Professional designed to test public gullibility. Holst created an absurd collection of bogus statistics, including the claim that humans swallow an average of eight spiders per year, to demonstrate how unvetted internet trivia spreads without verification.
The irony was immediate and lasting. The fabricated statistic outlived the original article, spreading across Usenet groups, forward-heavy email threads in the late 1990s, and early social platforms. By the mid-2000s, the claim had shed its satirical context entirely and entered pop culture as accepted trivia. The durability of the claim highlights how easily a vivid, fear-inducing number bypasses rational scrutiny.
