That's not what it says. I will give you an example. Before the 1980s or so when the first serious studies on second-hand smoke exposure were conducted, anybody could have also written that "we cannot provide a definitive causal link between second-hand smoke and lung cancer." Today, it is common sense.

Common sense nonsense: You can fall off the edge of the world You should put ice on burns We only use 10% of our brain
