I've seen people on this site comment that. The desire to live in fear is a strong one.

It's sort of a symptom of our poor mechanisms to create signalling and movement. We evolved to operate at the level of troops of baboons and, without utilizing the more potent capabilities of the trained mined, those mechanisms fail at the internet scale.

People often "believe" things as a means of signalling others. Deeply held "beliefs" tell us where the troop will go. Using these extremely compact signals helps the group focus through the chaos and arrive at a fast consensus on new decisions. When a question comes up, a few people shout their beliefs. We take the temperature of the room, some voices are more common than others, and a direction becomes apparent. It's like Monte Carlo sampling the centroid and applying some reduction.

This means of consensus is wildly illogical, but slower, logical discussion takes time that baboons on the move don't have. It's a simple information and communication efficiency problem. We can't contextualize everything, and contextualizing is often itself a means of intense dishonesty through choosing the framing, which leads to intense debate and more time.

Efficiency and the prominently visible preservation of each one's interests in the means of consensus are vital. I don't think we have reached anything near optimum and certainly not anything designed for internet scale. As a result, the mind of the internet is not really near its potential.

If I compare how fearful people are and how many bad things have happened historically, I don't think the amount of fear is unreasonable. However it can certainly be said that people fear the wrong things - worrying about perfectly safe things, while being blind to the silent danger sneaking up on them.
