One of the most interesting analyses on the ways in which our decisions kill us is one by Ralph Keeney (Operation Research, 2008), where Ralph puts forth the claim that 44.5% of all premature deaths in the US result from personal decisions – decisions that involving among others smoking, not exercising, criminality, drug and alcohol use, and unsafe sexual behavior…
Using the same method to examine causes of death in 1900, Keeney finds that during this time only around 10% of premature deaths were caused by personal decisions. Compared to our current 44.5% of premature deaths caused by personal decisions, it seems that on this measure of making decisions that kill ourselves we have “improved” (of course this means that we actually got much worse) dramatically over the years.
