Is there an example where individuals taking personal responsibility of a widespread problem has led to a favorable results? What I've seen is that this line of thinking disconnects the values from the result ie: "We did the right thing, so we have to accept the results." This re-frames the debate from results-orients to values-oriented.
The same reasoning is being used in the climate change debate. Corporations are gearing up PR teams to promote individual responsibility campaigns so that corporate action can be minimized. Again, it disconnects the values from the results so that at the very end when nothing changes a group can be happy that even though it fails, we did the right thing. The end result is cynicism and skepticism to these tactics.
