Micheal Vassar's
Correction

The post misspells Michael Vassar’s first name. Credible sources identify him as “Michael Vassar,” not “Micheal Vassar.”

Full reasoning

This is a straightforward name error. Multiple sources that identify the same person spell his name Michael Vassar.

  • On MIRI’s official site, the 2009 post “Introducing Myself” is authored by Michael Vassar and refers to him by that spelling throughout.
  • Big Think’s profile page likewise identifies him as Michael Vassar.

So the post’s text “Micheal Vassar's” is incorrect; the correct spelling is “Michael Vassar’s.”
