The Truth

A humorous introduction arrived on April 1

The answer is “a humorous introduction arrived on April 1.”

The first day of the new fiscal year is April 1, April Fools’ Day. Sawada announced his son’s birth in a humorous text like a new-employee introduction, and the email arrived just after midnight on April 1. Since the usually serious Sawada seemed to have deliberately sent a joking email, his colleagues took it as an April Fools’ joke. He was reporting the truth; the combination of date and style caused the misunderstanding.

Key Points

  • Read the date as a condition as well as the content
  • The writing style (a joking tone) affects how it is received
  • Even true news can be misread because of date and style

Why people get fooled

You think a true report should be believed, and overlook the combination of date and style.

Similar tricks

  • A mystery where the date is the reason
  • True content, different reception
