The main conclusion of the paper is that an education in astronomy no more qualifies the ability of a person to classify galaxies than does any other personal possession. Second, the accuracy of classifying galaxies is rather low, at just ten percent. Third, the paper concludes that the data provided by the public obviously shows differences between color and shape on a graph. Finally, the paper concludes that classification by shape is important because a large number of galaxies of one color are the same shape, yet organization by shape don't provide "traditional" classification based on shape. This might be trying to say that, when sorted by color, galaxies are not sorted by shape in the standard/expected sorting. I guess the conclusion is that color and shape of galaxies are not correlative because you cannot sort galaxies by color and produce the same organization as you would, were you to sort them by shape.
