They did not in fact find that the shorts are making you dumber. They said it affects your attention span.

Ironically I found this out in the first sentence of the article and then stopped reading.

Yeah I can’t imagine it making me dumber. Most of my shorts are interesting scientific facts/discoveries. Or CSS tips and tricks.

Attention span I can definitely believe.

This may shock you, but most people watch really dumb fucking shit instead of scientific facts.
