Good post!
Humans just tend to fear most what looks dramactic and is mentioned on media.
That is the reason why thousands of smokers worry about terrorism instead of their self damaging behavior.
That is also the reason why some fear vaccine side-effects more than the illnessen - even if they kill hundred times more often. (see: https://steemit.com/health/@theaustrianguy/the-big-psychological-dilemma-about-the-side-effects-of-vaccines)
This is also why many fear murder more than a car crash. Even if it is really unlikely to be murdered if you live in a western country and are not involved in criminality/gangs/... .

Human irrationality will be the topic to a big post I will make in the near future. As an aspiring doctor I have to deal with it every day.
