"No snowflake in an avalanche ever feels responsible." -- STANISLAW LEC
(snip)
When an individual has reason to contribute to what is basically a group activity in which the benefits of the group activity are shared by the group, certain puzzling phenomena are evident that can only be described as "diabolical". While there is no generally accepted terminology for these phenomena, various manifestations are often referred to as the "Voter's Paradox", the "Volunteer's Paradox", "Collective Action problems", the "Tragedy of the Commons", "Many-Person Prisoner's Dilemma", etc., or, in general, the "Social Dilemmas". The well known, two-person, "Prisoner's Dilemma" is just a special case of the "Social Dilemmas".
