Human intelligence and algorithms Have there been any studies to determine whether human intelligence can outperform algorithms (i.e. test whether the No Free Lunch Theorem applies to human intelligence)?

Along the same lines, has anyone developed a technical method to take advantage of any unique, supra-computational properties of human intelligence?
Check out Luis Von Ahn at CMU. He is the original Captcha guy. You will find enough videos like this  google techtalk on the subject of Human Computation.
