The present paper is an addendum to a previous study on the work that has been conducted during the eleven sessions of a group analysis training at the Basque Foundation for the Investigation of Mental Health at Bilbao. The participants were presented with an “absurd questionnaire” proposing 50 pairs of images, in each of which one image had to be chosen. The results of the previous study were in favour of the influence of group dynamics on individual choices of the images proposed in the questionnaire. Our present analyses complements the previous work with the exploration of the relations between the orientation of the answers in the groups as results of Multiple Variable Analysis and the distribution of Bernoulli’s Entropy. Consistently with the conclusions of the previous paper, we interpret these correlations as group effects in the light of Bion’s view of group dynamics, which postulates an immediate onset of a group unconscious and its evolution during the group activity.
