Something which would definitely have our politicians, bad cops, and citizens who commit the most egregious crimes running for the hills is if we were all taught how to read each other's minds. Though it would be panic at first as cornered rats do bite, it may be an interesting change in our social evolution.
My first attempt at reading a family member's mind:
"So, you did eat that last little tub of Ben & Jerry's ice cream! Our poor dog. You blamed it on him and I believed you. Grrr..." Chaos ensures.
