I don't think we really need to worry about rare and very rare side-effects. Or if we do, it'd be fair to also start worrying about all of them equally, but that would mean not taking any drugs ever.

> that would mean not taking any drugs ever.

It would mean quantifying the risks of side effects versus the risks of not taking the drugs, which we should be doing anyway.

Availability heuristic.

If you read "changes in personality" listed as a very rare side effect on the drug's sheet (which yes, you should read once when you start taking the drug), you can evaluate it, maybe make a mental note etc.

But if you make (or share) a bbc article on a particularly rare side effect, completely out of context, you're privileging the hypothesis. Why this particular side effects should be brought up for consideration? Other than in sounds weird and gets clicks.
