    I'm reading an article in the Economist and I can't understand what this means.
    A heavy-tailed distribution is a platykurtic distribution. This means that it has a kurtosis/standard error of the kurtosis ratio which disqualifies it from being considered a normal distribution.

    In non-statistical terms, this is a group of scores in which a considerable number of the scores are rather far from the mean score. The graph of such a distribution is flatter than that of a normal distribution, where scores cluster around the mean.
