Go to Dan's blog (Link below) and quickly summarize one of the stories/posts and relate the phenomena to one of the parts of Prospect Theory from the text along with explaining how the outcomes differ from what would be the actions of a rational consumer/person. Parts of Prospect Theory include mental accounting, endowment effect, anchoring, and so on. Make sure you explain the 'why' of the relationship between your example and the part of Prospect Theory. Provide a link back to the specific post.
