Why didn't we take P.Diddy and R.Kelly seriously when the signs were always there, is there a name for this phenomenon?

I've seen a bunch of clips online some from years ago like one of R. Kelly saying he had a crush on his mom and loads about Diddy. At the time, people either brushed them off or didn’t take them as seriously as they do now.

Looking back, it seems wild that we didn’t see these things for what they were. Is there a name for this phenomenon, where people overlook red flags or dismiss information until it becomes undeniable in hindsight?
