Today, a short tumblr post from user squarerealworthy:
Everyone will not just
If your solution to some problem relies on “If everyone would just...” then you do not have a solution. Everyone is not going to just. At not time in the history of the universe has everyone just, and they’re not going to start now.
Identifying a problem is easy enough. So too is coming up with a solution that would work if you could snap your fingers and coordinate everyone’s behavior instantly, aligning everyone’s incentives, ignoring all the psychological diversity around us.
Much harder is finding solutions that work even in a messy world, where people are imperfect.
