That seems like a variation of the Trolley Problem. Psychologically, the risk that you take by not acting feels more attractive than the one you take by acting, because you're not actively choosing it and therefore aren't responsible for it.There are two additional human traits, that play into a lack of preparedness.
Humans are bad at telling the difference between actual risk and perceived risk, so we tend to (at least personally) prepare for the wrong things. It's why so many people refuse to take a vaccine, with a 1/100,000 negative result, but instead will risk a disease that has a 1/1000 negative outcome. I wish that I could remember who wrote a scholarly book about this very thing, just a few years back, because I would very much like to read it.
