Let's assume for a moment that there exists an individual who (via unknown mechanisms) knows about 90% of the hidden affairs of marriages in the world.

Should that person "blow that whistle", as it were, suddenly turning almost all relationships "honest"? Or would it cause widespread havoc and upheaval?

>Should that person "blow that whistle"

Ask the people who are being cheated on. Or spied on.

I'm not suggesting an answer. I'm posing a thought experiment. I think it's a reasonably good analogy.

My answer is probably odd- I'd want to know if I was the possible jiltee, but I don't know if I'd say that it should be revealed for ALL people.

That depends on which side of the whistle you find yourself.
