This is sort of a corollary of avoiding being too naive when accepting product feedback. People often don't know how to express what they want, often they don't even know what they want. For every "shut up and take my money" moment there are many "I didn't even know I needed/wanted that" moments. So much of being an effective inventor is being able to have one foot in consumer land and one foot in product land and be able to translate between them.
