I think there's some evidence, take the old saying "three can keep a secret if two are dead" or it's variations. Even the Bible warns about how easily things get spread around.
But the Internet and communications moving to online text, etc, greatly increases the provability of the gossip, if you will. Which is a major change that we as a society haven't really adapted to. We treat "private" or "direct" chats as like talking in a cornfield; but before you just had a he said/she said situation, now someone can "drop receipts" or you can have whatever platform you're on hacked and everything spilled.

I was reminded of this just a few weeks ago. Told a few people some news I told them was non-public given I was seeing them in person. Wouldn't you know it, it immediately got up to someone I'd just as soon not have known. Wasn't really a big deal but still annoying.
Common sense? Lived experience? No privacy is probably an overstatement (as absolute statements tend to be). But my experience having gone to university and living with a group of people was that you tended to learn a lot about other people's lives. And that's almost certainly more privacy than in a tribe.
