Psychological history

The aim of this article is to prove, based on a specific application, that historians are wrong when they refuse to take the insights of psychology into consideration in their conceptualisation of the past. Particularly observational and behavioural assessment techniques as they were developed in personality psychology can be very valuable to historians. We would like to illustrate this by looking for an answer to the question: is it correct to say that individuals beatified by the Roman Catholic Church in the 19th and 20th centuries are characterised by a parallel personality profile?
