If there were a science of user interaction, its second law could be called the Wide Angle Fallacy. When a disgusted user goes back to the designer saying, “Your system doesn’t perform the special function I need,” the designer’s ego is deeply affected. To regain the good graces of his customer—and to re-establish his self-esteem—the designer is likely to answer, “I can fix it in no time. I will just add another command for you.” Later, the same man will be seen at conventions, meetings and workshops, extolling the virtues of his system, the “power” of which can be measured by the great number of commands it can execute. I believe this is usually a fallacy and users should recognize it as such. — Jacques Vallee, The Network Revolution: Confessions of a Computer Scientist (1982) chapter six, Obfuscatology (https://books.google.com/books?id=6f8VqnZaPQwC https://books.google.com/books?id=6f8VqnZaPQwC)
