Are you turned off an unread (by you, natch) book if the positive reviews quoted on the cover are all or mostly taken from papers you don't like (particularly right-wing ones like the Torygraph)?
I don't notice/care about reviews
I hate books. Go away, you speccy swot
I say this because I review a lot of popular/social history books, and I am always turned off ones whose author has been previously praised by the likes of the Mail, even before I start reading them. Am I mad?
