So I was reading the list of http://en.wikipedia.org/wiki/Seven_deadly_sins and I was impressed with the list (seeing how many of these sins are what ultimately bring down many major historical figures). I also recognize how many of these sins were responsible for some of my major setbacks in life, and am thinking of creative ways to reduce their effects (by putting value on things that don't involve any of those sins).
I'm curious: to what extent do the "seven deadly sins" cover the most common reasons why people engage in self-defeating behavior? Are there any major omissions in the list of "seven deadly sins"? If you were to make a list of "X deadly sins", which sins would you include?
As examples: should excessive guilt be counted as a sin? Should stupidity be counted as a sin? What about being excessively "autistic"?
Which of the "Seven deadly sins" do you think are most applicable to LessWrong posters? To what extent are they responsible for akrasia?
