I think it's more like people are looking for a solution, not a description of a problem (at least if you're running any tech-related forum - not sure about other niches). The description is on page 1 but the solution may be on page 7 and Google is helping users get there quicker. There's nothing you can do about it; I'm not sure you even need to. My guess is that you ultimate goal is to convert a casual surfer into a member and they are probably going to be more inclined to join if they see answers quicker.
I do realize it cuts down on your ad impressions - struggle with it myself. But there's probably a long term benefit in this, at least I hope so.
