This document discusses several concepts related to economics and human behavior: 1) The Streisand Effect describes how an attempt to suppress information can sometimes inadvertently increase its publicity. It references Barbra Streisand's unsuccessful $50M lawsuit that aimed to remove an aerial photo of her home but instead drove more people to view it. 2) Gresham's Law states that "bad money drives out good" - meaning that when overvalued legal tender currencies circulate together, the undervalued currency will disappear from circulation. 3) A Schelling Point refers to a situation where people coordinate their behavior based on mutual understanding of what others might do, without any explicit communication or agreement.
