For example, Suppose on average 1% signup for the military in high school. Next suppose we add an intervention, we add a sign in the lunchroom for military recruiting (touching on all the right emotions). The average in these schools goes up to 3%! We say, these additional recruits CHOSE to join, but we know they wouldn't have had we not added the sign.
It's in this way that I say that realtime voting doesn't solve the problem, because it doesn't look holistically enough, namely at influence. It's not just at the ballot box, but in your daily life. The question then becomes, who can influence and how much?
