How do we make and enact better decisions?

In the early 1970s, a retailer, projecting their growth forward into the future, began construction on a 108 story office building in downtown Chicago. It was never fully used by the company and large portions were vacant throughout the 1980s.* Today, the 103rd floor of the tower has a good demonstration of the difference between alief** and belief, as you can look straight down 1353 feet through a glass ledge.

The time, money, and effort put into that building could have been used instead to improve lives though effective charity, or simply been used to improve the retailer's marketing instead. While most decisions that we make in our everyday lives do not have that much impact, what we believe about the world (epistemic rationality), and how we interact with it (instrumental rationality)***, can have a large impact on our lives.

This Meetup group is for all those in the Chicago area who want to improve their thinking and deciding, with particular interest to the Less Wrong community blog.
