I agree. It's confusing to be taken to a different page than you saw in the search results, with potentially none of the words you searched for. (Duplicate questions are often better written—that's why they appear higher in the search results). A header informing 'you have been redirected' would resolve that objection. Wikipedia does this http://meta.stackexchange.com/a/125245/168589

It's also duplicitous to show different pages to search engine crawlers than to anonymous readers. This is one reason people dislike Quora.
