This document discusses different types of decision making. There are two main types: involuntary decision making, which occurs out of habit or repetition, and voluntary decision making, where one examines all available information and alternatives. Voluntary decision making can be influenced by credible sources, authority figures, peers, groupthink, and interpersonal needs for affection, inclusion and control. The document emphasizes that critical thinkers should evaluate both the decision making process and outcomes when assessing a decision.
