I actually read that they did a study scientifically disproving the rule.
Personally, I think the study was a waste of time. All they had to do was ask me.
I read this in an article (probably on Aish.com) explaining how the same concept applies to Ruchnius; You shouldn’t think that if you flip the page or log off as soon as something inappropriate comes on, that you weren’t affected by that split second.
