Fundamental Error T-Shirt

Fundamental Attribution Error — “You’re careless. I’m just unlucky.”

A clean, minimalist tee capturing one of the most common psychological blind spots: we judge others by their character, but excuse ourselves with circumstances. The split-panel faces show the double standard perfectly — it’s you versus not me. A sharp, thoughtful design for anyone who appreciates cognitive biases, self-awareness, or the quiet humour of human inconsistency.
