It’s simpler and more insidious than that. I’ll use the old Eleanor Roosevelt quote:
"Great minds discuss ideas; average minds discuss events; small minds discuss people."
Most people are not that intellectual and probably spent most of their life gossiping. They wouldn’t know how to even discuss certain topics if the low hanging fruit of gossip and conspiracy wasn’t available to them to add something in a social interaction.
Take Reddit for example, some of them wouldn’t even know what to say if they couldn’t add that one immediate punch line (followed by sequential punchlines by other people). If you take this away, they will literally have no way of joining the convo.
They won’t be able to come up with an angle, ask a probing question, entertain an alternative perspective, provide analogues or metaphors, they’d simply have no voice. It’s akin to providing these people with ‘what do you think about the weather today?’ as a lifeline in casual social interaction.
