Mario Speedrun Placebo Effect

possibly the single greatest placebo effect/enclothed cognition experiment of all time??? Super Mario Bros. speedrunner Niftski broke the world record while dressed as Mario, coming within two frames of a theoretically perfect run His 4:54.299 time is just 33 milliseconds behind the 4:54.265 ... MARIO 0917 SUPER MARIO BROS. ENTERTAINMENT SYSTEM Nintendo

A tweet jokes that Super Mario Bros. speedrunner Niftski nearly achieved a theoretically perfect run while dressed as Mario. The punchline is that wearing the character’s outfit may have created a placebo or “enclothed cognition” effect, making the costume seem like a performance enhancer.
