Le Bon thinks that the particular acquirements of individuals become obliterated in a group, and that in this way their distinctiveness vanishes. The racial unconscious emerges; what is heterogeneous is submerged in what is homogeneous. We may say that the mental superstructure, the development of which in individuals shows such dissimilarities, is removed, and that the unconscious foundations, which are similar in everyone, stand exposed to view.
In this way individuals in a group would come to show an average character. But Le Bon believes that they also display new characteristics which they have not previously possessed, and he seeks the reason for this in three different factors.
'The first is that the individual forming part of a group acquires, solely from numerical considerations, a sentiment of invincible power which allows him to yield to instincts which, had he been alone, he would perforce have kept under restraint. He will be the less disposed to check himself from the consideration that, a group being anonymous, and in consequence irresponsible, the sentiment of responsibility which always controls individuals disappears entirely.'
