a lot of interesting questions. Social science will become more data driven, what i guess is not a good thing. Remember the german positivism battle - Popper VS. Adorno. But when data driven it will be definitely better with blockchain. BUT - the big problem is. Data can just measure the current status of society, not the past, not how people can be and interact. So, for sociology we cant just measure, we must develop good theories and use data too, but not fetishize bits and bytes. Social science is not less scientific it is another science with own methods, working better for the subject.
