"People are afraid of flying once a year and yet stuff 3000 Calories a day. How do you figure our human perception of risk and personal responsibility there?"
Risk evaluation is highly subjective: flying may be totally unacceptable to others but totally acceptable to you.
So it is entirely reasonable for different people to settle on different compromises yet both are optimal to their respective risk takers.
It is totally unreasonable to think that others risk compromises are wrong simply because they differ from your compromises.
Risk evaluation is a science. It is not subjective. It is based on evidence and statistics - and if not manipulated - pretty good at forecasting future statistics.
However, like most statistical based practices, it is highly counter-intuitive (especially for the public) and is also prone to changes over time (e.g. the inventions of seat belts and electronic traction control have changed car accident related statistics considerably).
The public has a tough time even grasping the (rather simple) difference between statistical correlation and demonstrating causality. Hence some people in the public really believe that being a Vegan makes you healthier... (of course - if they wouldn't have mistaken correlation with causality they would have asked to compare the health nuts in the Vegan and Non-vegan groups - numbers change considerably once the right question is asked...).
People in any case will make up their minds based on anything they want to. But dragging them through multiple stories will not help them focus on facts (when the flight went down on FB were like "terrorism", "fire", "fault", etc.; now with the German and Egyptian airliners, some people are now like "all the pilots are now committing suicide all over the world"). Why?
