Hi Stuart:
This is a follow-up to Stephen Black's point that the
radiologists were looking for cancer signs and not for other
irrelevant images.
What were the instructions that the radiologists and the controls
were given?

Dear TIPSTERS,
I held back on this until I had some facts.
The immediate question that came to mind was "If 83% of radiologists did not see the
gorilla, what was the rate for non-radiologists?"
That is, was there a control group.
Dr. Drew has kindly supplied me with a preprint of his manuscript and here are
the facts:
Of 24 radiologists, 20 failed to detect the gorilla.
Of 24 non-radiologists, 24 failed to detect the gorilla.
Now that puts a different spin on what I have heard all over the media.
Sincerely,
Stuart
