Self-explanatory, but Munger makes an interesting point that envy/jealously tendency is surprisingly absent from most Psychology textbooks.
Envy/jealously tendency comes from the need to get often-scarce food, this occurs often when the food is seen in possesion of another member of the same species

This may mean letting a driver merge infront of you or perhaps carrying more physical load for a short amount of time to benefit your group. This bias has been hard-wired into our brain from thousands upon thousands of years, in ancient times food was often-scarce, food seen in possesion of another member of the same species triggers envy and jealousy.
Great. Sooo show your prospects that their competitors are using the same product/service that your selling and show them HOW WELL their doing bc of THAT SPECIFIC product.
This will initiate the envy / jealousy bias and will aid in having a successful sell.
