simon - its perfectly possible to ascertain why people voted the way they did.
You call a bunch of them afterwards and ask them ;-)

http://whatscotlandthinks.org/ is also an excellent resource
People voted yes because of self-determination, Westminster politics and whats happening with the NHS
People voted NO because of risk, pensions and the pound.
Independence is a processs, not a referendum date. It has been successfully underway since 1998. It's surprising people are unable to see the bigger picture.
