I got that "did you know binaural beats can do you more harm than good?" ad when i clicked on this video.
Yep! Scam, scammity-scam. The man in the lab coat is NOT a neuroscientist. He's an actor named Frank George and he records these videos on Fiverr!
If you want to report the ad, that'd be helpful... https://www.youtube.com/watch?v=ywH4Si71Fjc
Under the video there's the "3 dots" -- click it, then hit Report. Choose "Spam or misleading", then "Scams/fraud" :)
