Abstract: According to Benford’s law, the first digit of a random number does not follow a uniform distribution, as many people believe, but a logarithmic distribution. This law was at the begining purely experimental, but it is now established that it holds for various mathematical series and some natural data sets. Concerning data sets, Benford’s law often appears as a good approximation of the reality, but as no more than an approximation. Our aim is to present a new explanation for this law. We argue that it should not be considered as a mathematical paradox, but as a purely psychological paradox, a result of a cognitive bias. We express a general criterion of regularity on a random variable X and prove that, whenever X follow this criterion, X is approximately Benford
