Has polling itself caused the shift in Scottish sentiment towards independence?

I think this is a classic case of how measuring something causes it to change

SCOTTISH voters are turning strongly against independence, according to the latest opinion poll, which shows the cross-party No camp charging ahead with a record 20-point lead.

The snapshot by TNS BMRB – taken after both campaign launches – puts those against independence on 50% and those in favour on 30%; the latter figure being the lowest received for independence in five years of surveys by the Edinburgh-based pollster.

Six months ago, the gap was nine points in the No camp’s favour; a year ago, it was one point in the Yes camp’s favour.
