Good point about posting about problems. Hadn't even thought about that.I'm thinking that a normal "posting bias", if you will, makes it impossible to make any inference about what is happening at larger scales just from trends in social media postings. How many people post with "My Chickens are Laying Exactly as Usua!" or "Everything is Completely Within the Normal Variations for Chicken-Owning!!!!" (unless it's replying to an opposite problem posting)?
In general, I see social platform postings being extremely biased toward reporting problems and worries, because that's when people feel the need to check in with others. So that any increase in social reporting doesn't necessarily reflect any increase in what is actually happening across the population. I think this would be a normal phenomenon and would happen even if no one was trying to be fear-mongering or had any agenda (although some probably do).
The posters above are saying this too and the summary that "saysfaa" wrote is accurate, so if you don't want to contribute to the click count you don't need to
I know of lots of other known biases in data collection, I wonder if "posting bias" has a real name?
