Correct, because there truly isn’t a great way to answer with certainty - there was evidence in the 80s of suggestive techniques being used by poorly trained psychologists, and there are many people who remember and then find corroboration.
There’s a lot more who remember and may not have corroboration more than with themselves and among their close friends or healthcare provider. Part of CSA is usually there is very little a kid can do about evidence, as the power discrepancy is far too much. Often with rich abusers, the exact same process occurs. Perps pick victims who are vulnerable or controllable, and constantly seek power and domination. Nothing to do with the boardroooms or batch of ceo billionaires running the economy right now certainly.
