> To a nerd, that avoidance is a very bad thing, because a nerd prides himself on knowing the details. > So the marketing message that avoids details and tries to sell some "powers" that work "out of the box" hurts the ego of the nerd. This feeling of hurt is certainly an emotion, so I wouldn't say nerds are less emotional! I think you're missing something fundamental here, possibly because of some connotation about "nerds". When I buy something, I want to know details about what it does and how it works, not because I like knowing a million details, but because I want to do stuff with it. If I buy a laser pen, I'm going to use it to play with my cats, but I also want to use it as a range finder with a diode, so I want to know the beam spread and wavelength. If it doesn't fit the specifications, I don't want to know about the other features, they don't matter at that point.
