If we need qualitative research, and this is taking place, we can get it anytime. A comprehensive policy is being followed in regard to the language. We must also be careful about research, which is often largely influenced by how one asks a question. There is the famous case of the car manufacturer who asked people what kind of car they wanted. As most people like to appear sensible, they answered that they would like a very sensible solid car and so on. When the car went on the market it was a total failure. The second survey was carried out slightly differently. People were asked what they thought their neighbour would want and they said they would want a big flashy car, with plenty of gadgets such as electric windows and so on. That car sold like a bomb. The way one asks a question can prompt the answer. It is difficult to get to the hard science of the matter, no matter what sociologists tell us.
As we are all aware, one of the reasons we need politicians is that, even though one might get all the evidence, it does not prove to be that useful when one tries to do the thing in practice. I am a great believer in the wisdom of the political system. It is often the best opinion poll of all because sometimes the antennae of politicians are much more accurate than surveys since sometimes questions are loaded to provide a specific answer.
