Very interesting read. I think this negative bias is often exploited by conspiracy theorists. For example, vaccines (as mentioned in you article) have improved human life by nearly unimaginable extends. But still, there are - I have read a lot of that here on Steemit - those anti vaccination conspiracies. "Big Pharma" wants to take all money from us and makes us sick. No-one cares about the fact that decades ago child mortality because of sicknesses now prevented by vaccines was so much higher.

Let's hope, humanity will start thinking more rationally. Thanks for the article!
