Munger uses the term “Lollapalooza Effect” for multiple biases, tendencies or mental models acting at the same time in the same direction. With the Lollapalooza effect, itself a mental model, the result is often extreme, due to the confluence of the mental models, biases or tendencies acting together. During a talk at Harvard in 1995, Munger mentions Tupperware parties and open outcry auctions, which turn the human brain into “mush”. In the Tupperware party, you have reciprocation and social proof. (The hostess gave the party and the tendency is to reciprocate; other people are buying, which is the social proof.) In the open outcry auction, there is social proof of others bidding, commitment to buying the item, and deprivation super-reaction syndrome, i.e. sense of loss. The latter is an individual’s sense of loss of what he believe should be or is his. These biases often occur at either conscious or subconscious level, and in both microeconomic and macroeconomic scale.
