And in Joy, he creates his most extensive outline to date about how to cope through humor. He categorizes humor then illustrates each area with his comics. He also encourages people to think creatively even though this carries a high risk of failure. For Adams, the benefits of humor are purely personal. I haven't seen evidence that laughter helps a company's bottom line.
Some companies are loose and creative and have a lot of laughter.
Other company cultures are dark and repressive, and their employees tend to participate in dark humor. Both companies can do just fine on the stock market, leading me to believe that the benefits of laughter are personal. Prank humor is tough to write without becoming shrill or thin. If Adams stopped there, then Joy would merely be a funny book about human frailty. By adding an in-depth discussion about humor and creativity, Adams creates a minor classic.
