How can Decision-making be Improved?

Found an interesting paper written by Katherine L. Milkman, Dolly Chugh and Max H. Bazerman on the topic.

The paper broadly talks about System 1(intuitive) and System 2 (explicit, effortful) of decision making and points out three ways of moving from System 1 to System 2:

a.) Gather historical data and analyse.

b.) Look at the situation and the implications of your intuitive decision as an outsider.

c.) Weigh the implications of a decision that is exact opposite of your current decision to see if your current decision has merit.
