O estudo está errado.

I find two spaces after a period unsettling, like seeing a person who never blinks or still has their phone’s keyboard sound effects on. I plan to teach my kids never to reply to messages from people who put two spaces after a period. I want this study’s conclusion to be untrue—to uncover some error in the methodology, or some scandal that discredits the researchers or the university or the entire field of psychophysics.
