Statistics experts are fewer and further between than experts in other fields who use statistics to justify their decisions, and the article shows how far off base most people are...after all the author conducted numerical analysis of the database and presents their findings as facts about data and includes a rough statistical comparison of the voting patterns of the lowest rated [called 'worst'] and the second lowest rated movies. If there is an interesting statistical result it's that the movie's rating is entirely consistent with crowd sourced predictions. The theory is that 'wisdom of crowds' results directly from diversity among those making predictions.[1] In the case of the lowest rated movie, those making predictions were unusually homogeneous, and therefore an inaccurate prediction as to the quality is unsurprising. Again, it's all in the interpretation, e.g. there's statistical evidence that a lot of morons ranked the The Matrix.
