Its quite a well-known wisdom. I think someone in one of Nintendo or Sony's studios has said it too, in the form of: a complaint is worth twice a compliment.
Satisfied customers will tell you they think your stuff is great, but dissatisfied customers will be able to hone in on exactly where the problem is.
You can even extend this to personal life: if someone tells you your shabby car doesn't fit with the nice suits you wear, you can either take it as a personal attack and get irritated, or take it as feedback and wash your car, spruce up the upholstery and replace the missing wheel cap. In effect they helped you take note of something.
