Group Mentality, as theorized most rigorously by W.R. Bion in his 1959 Experiences in Groups, designates the unanimous, anonymous expression of a collective will that operates beneath the level of individual conscious intention. For Bion, group mentality is not a mere aggregate of individual wishes but a sui generis phenomenon: a pooled psychic deposit to which each member contributes without awareness, and which may conflict sharply with the private desires of any single participant. The concept is inseparable from Bion's correlative constructs of group culture and basic assumptions — the primitive, instantaneous emotional states (dependency, fight-flight, pairing) that seize a group and divert it from rational work. Freud had earlier characterized the herd as a regressive, contagion-driven lowering of individual mentality, and Bion inherits this tension while pressing beyond it: he insists that the individual is constitutively a group animal at war both with the group and with that aspect of himself that belongs irrevocably to it. Flores, reading Bion through an addictions lens, foregrounds Freud's alarm at the group as a source of 'contagious reduction of mentality.' The wider depth-psychological corpus reveals that group mentality intersects persistently with questions of leadership, regression, basic assumptions, and the conflict between work-group rationality and the archaic emotional pulls that subvert it.
I have suggested that it helped to elucidate the tensions of the group to suppose the existence of a group mentality. This term I use to describe what I believe to be the unanimous expression of the will of the group, an expression of will to which individuals contribute anonymously.
Bion's foundational definition: group mentality is the anonymous, unanimous collective will that underlies and often contradicts individual conscious intention.

Bion recounts how clinical resistance to interpretations framed in terms of group mentality and group culture forced him to reformulate his theory toward the concept of basic assumptions.

Flores presents Freud's foundational position — contra Bion's nuanced revision — that group participation degrades individual mentality through regressive contagion and enforced conformity.

to be quite unable for an appreciable time to grasp a fact that could not be a matter of doubt in work-group mentality. What is ordinarily called impatience must therefore, in the basic-assumption group, be considered as an expression of the anxiety
Bion distinguishes work-group mentality from basic-assumption mentality by showing that temporal impatience, unremarkable in the former, signals profound anxiety in the latter.

The individual is a group animal at war, not simply with the group, but with himself for being a group animal and with those aspects of his personality that constitute his 'group
Bion articulates the deep structural conflict: the individual is constitutively a group animal and is therefore in conflict with both the group and with his own inherent 'groupishness.'

the apparent difference between group psychology and individual psychology is an illusion produced by the fact that the group brings into prominence phenomena that appear alien to an observer unaccustomed to using the group.
Bion, aligning with Freud's critique of herd-instinct theories, argues that group psychology reveals latent individual phenomena rather than constituting a distinct ontological category.

There is a matrix of thought which lies within the confines of the basic group, but not within the confines of the individual.
Bion posits that the basic group generates a matrix of thought inaccessible to the isolated individual, grounding group mentality in a genuinely collective, non-reducible psychic space.

The belief that a group exists, as distinct from an aggregate of individuals, is an essential part of this regression, as are also the characteristics with which the supposed group is endowed by the individual.
Bion argues that the very perception of 'the group' as a distinct entity is itself a product of the individual's regression, revealing group mentality as a phenomenon inseparable from regressive processes.

the individual cannot think in the group is often heard. He will try to feel secure in his membership of the group but will endeavour to split off the disliked feelings that are in combination with this desirable security
Bion traces the individual's use of splitting as a defense against the emotionally complex demands of group membership, illustrating the psychological cost of participating in group mentality.

group mental life is essential to the full life of the individual, quite apart from any temporary or specific need, and that satisfaction of this need has to be sought through membership of a group.
Bion asserts the positive necessity of group mental life for individual psychological completeness, counterbalancing his account of its regressive and frustrating dimensions.

what is this group which is unsympathetic and hostile to our work? I must assume that it consists of these same people that I see struggling hard to do the work
Bion illustrates the double-focus problem: the same individuals who consciously strive to work simultaneously constitute a group entity that opposes that work, exemplifying the split between work-group and group mentality.

A group structure in which one member is a god, either established or discredited, has a very limited usefulness. The culture of the group in this instance might almost be described as a miniature theocracy.
Bion offers a vivid clinical illustration of how group mentality projects divine or oracular status onto the leader, producing a theocratic group culture that forecloses genuine therapeutic work.

if the therapist suspect that his high opinion of himself is shared by the group, he should ask himself if his leadership has begun to correspond with that demanded by the basic assumption of the group.
Bion cautions that the therapist's sense of authority may itself be a product of the group's basic-assumption demands rather than genuine clinical competence.

a shift of point of view, admittedly of some magnitude, on my part, means that I am viewing group phenomena that do not 'begin'; the matters with which I am concerned continue, and evolve, but they do not 'begin'.
Bion makes a methodological aside distinguishing the temporality of group phenomena — continuous and evolutionary — from the punctual 'beginning' that work-group convention assumes.
