Counter intuitive clockwise

The Bad Astronomer (my favorite blogger) who is attending the American Astronomical Society (AAS) meeting in Austen, Texas has an interview with Chris Lintott at Galaxy Zoo about their project to classify galaxies. People who are participating are asked to classify galaxies. First whether they are elliptical or spiral galaxies and if they they are spiral whether the spiral arms rotate clockwise or anti-clockwise. Strangely people are finding more galaxies that are anti-clockwise than clockwise. This makes no sense at all. We should find approximately the same number of each type. By using a neat trick the project discovered that it is not the Universe that is weird, it is us.
