I did the original survey last year on which these latest categories were based. I think the question about who you know socially was designed to see how wide or how how narrow your social contacts are, not if they fall into a narrowly defined group. The same with the cultural experiences. So for example football is weighted equally with opera (not that I go to either) but I think it wasn't being judgemental about categories at all, just looking at breadth.
think you can still take part in the originally survey. There are a few other interesting ones too. I seem to remember one was designed to see how 'moral' you are, or rather how you conform to feelings of distaste about certain behaviours. And there's another about some sort of skill, which I forget now. But it was one of those where logical thinkers and those who are good at maths do well. I'm not revealing my score on that one! But my husband had a most superior look on his face for some time.
