A working motto Herzberg applies to product and marketing decisions alike: if a proposed feature, answer, or decision feels overly complicated to explain or execute, that complexity is itself a signal the current solution isn't the right one — not a problem to push through with more effort.
The prescribed response is to stop forcing the complicated version, set it aside, and return to the problem later for a simpler alternative, on the assumption that the right answer, once found, will feel simple rather than convoluted. Contrast with Friction as Decision Signal (Harder-Choice Heuristic), where difficulty of choice is treated as a positive signal; here, difficulty of explanation is treated as a negative one.
