In 1763, an article by Reverend Thomas Bayes was published in England; the article became famous for its implications. According to the article, making predictions about a phenomenon depends not only on the observations that the scientist obtains from his experiments, but also on what he himself thinks and understands of the phenomenon studied, even before proceeding to the experiment itself. These premises were developed in the 1900s by distinguished scholars, such as Bruno de Finetti (La prévision: ses lois logiques, ses sources subjectives, 1937), L J Savage (The Fondations of statistics Reconsidered, 1959), and others.
