A Brazilian point of view on the trajectory of this forgotten concept in the quantitative approach of the law, with code and examples in free software. Keywords: Jurimetrics, Law, Statistics, Thomas Bayes, Lee Loevinger, Artificial Intelligence, Empirical Legal Studies. 1 Old Wine in New Bottles he year 2019 is interesting in a ‘jurimetrical’ point of view.

The conceptual framework of jurimetrics was first presented (2019 − 1949)=10 = 7 decades ago by [Loevinger(1949)]1. His manifesto begins considering that ‘one of the greatest anomalies of modern times that the law, which exists as a public guide to conduct, has become such a recondite mystery that it is incomprehensible to the public and scarcely intelligible to its own votaries’.
