About this site
Who is Joel?
Joel is a good friend and a bottomless well of near-knowledge. He is never badly wrong — never a conspiracy, never a grift — just wrong enough to be interesting at dinner, and confident enough that nobody checks until the drive home.
A note on accuracy
Every fact on this site is completely true, except the part Joel says. Corrections are simplified for tone and for length. Mildness is scored on a scientific scale from barely wrong to impressively wrong, calibrated by how hard Joel would argue.
“I'm not saying I'm right. I'm saying I've never been meaningfully corrected.”
