To me it looks like a pair of pirouetting wolves. Others in the Independent office suggested a butterfly and one forensically inclined colleague thought it was a pelvis. Whatever you see, it could just open a window on your soul.

For decades, psychologists have used the Rorschach ink blot test to provide them with an idea of the sort of person you are. They show you a random pattern - the ink blot - ask you what you see and record your response. From that, the theory goes, they can construct a picture of how your mind works, and what may be wrong with it.

Now a Canadian doctor has spoilt the fun by posting on Wikipedia the 10 ink blot images used by Herman Rorschach, the Swiss psychiatrist who developed the test in 1921. And, in a move that has angered psychologists even more, he has posted alongside the images the commonest responses they evoke. Critics have besieged Wikipedia protesting that this is tantamount to publishing the answers to exam questions before anyone has sat the exam. It risks invalidating one of the oldest psychological tests in use.
