AT times like this, my mind drifts to the Rorschach test, that fascinating set of ink-stained images that tell us all we need to know about the Scottish Tories.
The Rorschach was a test developed by the Swiss psychologist Hermann Rorschach in 1921 to measure our thought disorders and to establish the sad psychological fact that in life, irrespective of the shapes set out in front of us, some people see what they want to see.
Rorschach has been deployed by America as a military personnel test and was most recently popularised in the 1986 graphic novel, the Watchmen, as the code-name of Walter Kovacs, the violent and ruthless vigilante featured in the comic book series.
