Maybe the reason humans are so stupid is because we have such low expectations of each other. Think about the signs we read everyday:
"No weapons allowed on campus." (okay, good for me to know, and my guess is that those who want to bring the weapons could give a rats ass.)
"Shirts and shoes required." (so, I can come half-naked????)
I also love how the trash cans thank us for throwing our trash away. Imagine that, getting thanked for being civil.
And did you ever think about how at basketball games when the home team is winning they have signs flash that say "cheer!" "clap!" "shout out loud!". Guess we have to be prompted to do that too.
The bar has reaaaaaaaalllllly been lowered.
