Once you see that an answer is not serving its question properly anymore, it should be tossed away. It's just their natural life cycle.

You see, too many actions have been based on those answers. Too much work and energy invested on them. They feel so important, so full of themselves. They will answer to no one. Not even to their initial question!
The hardest thing about customer interviews is knowing where to dig. An effective interview is more like a friendly interrogation. We don’t want to learn what customers think about the product, or what they like or dislike — we want to know what happened and how they chose... To get those answers we can’t just ask surface questions, we have to keep digging back behind the answers to find out what really happened.
In no objective sense were things better for UX [in 2010]. Most companies didn’t know it existed. Most who did, drastically underinvested in it. Those who were willing to invest in it were savvy enough to listen to thought leaders, but that was a paltry percentage of the real work to be done.
