Aaron T. Beck published Love is Never Enough (about marital relationships) in 1989. William Ury and Roger Fisher originally published Getting to Yes (about principled negotiation) in 1981, but I have been unable to discover which edition the particular anecdote I'm referring to was first included in.
Aaron T. Beck's book includes a story about a husband and wife who were having conflict over whether to leave the window open at night. After questioning about why they wanted it to be that way, the wife stated that she wanted the fresh air because she found it too stuffy, and the husband stated that the draft bothered his asthma. His recommended solution was to open a window in an adjoining room.
Ury and Fisher's book include a hypothetical scenario in which two men were arguing about whether to open the window in a library. After questioning by the librarian, she found that one of them wanted fresh air and the other one wanted to avoid a draft. Her solution was to open a window in an adjoining room.
These two anecdotes seem too similar to be coincidental. Did one of them borrow from the other one? If so, which one? Aaron T. Beck seems to imply that this was an actual scenario from a therapy session he conducted, whereas Ury and Fisher only present it as a hypothetical scenario; however, Aaron T. Beck's book was published in 1989 and Getting to Yes was published in 1981. Also, Dr. Beck's narrative of his approach to helping couples resolve conflict seems remarkably related to Ury and Fisher's concept of principled negotiation.
This leads me to believe that Aaron T. Beck read the 1981 edition, incorporated it into his therapeutic practice, wrote the anecdote in his 1989 book, and then Ury and Fisher adapted it for subsequent editions of their book. However, this is rather speculative on my part, and I have not been able to find conclusive evidence either way. Is anyone aware of evidence as to who influenced whom here?
