No you don’t. Type “social network” (no quotation marks) and press enter, Google will then search only for what you typed, without the suggestion. It’s not exactly obvious that you can do that but it makes sense. You can use Instant just as you used Google before and still get the same behavior, they seem to have taken great care of making this behave exactly like before (i.e. typing something and pressing enter will only search for exactly what you typed, pressing enter adds an entry to your browser’s history just as before, etc.).
