I'm sure there are examples of safetyism that have really made people safer with low downside (hand-washing in hospitals? Bicycle helmets?) but very often there is the kind of situation described in this article: things actually get worse.
In this case, it seems that cigarette filters led to people inhaling more deeply (leading to higher rates of cancer) and some filters were made out of toxic materials (asbestos) and the filters become a non-biodegradable piece of garbage that just cruds up the place.
I don't like safetyism. What are some other examples of stupid things humans do in the name of safety that make things worse?
