The Dependency Basic Assumption occupies a foundational position in Bion's tripartite theory of group mentality, representing one of the three covert emotional states — alongside fight-flight and pairing — through which groups evade the demands of genuine work. In Bion's formulation, the dependency assumption organizes group life around an implicit fantasy that an omnipotent leader will provide total nurturance and protection, rendering members passive recipients rather than active contributors. The corpus reveals several significant tensions attending this concept. Flores, drawing on Bion's clinical framework and supplementing it with Kernberg's observations on leader personality, demonstrates how the dependency assumption functions as a form of group resistance particularly germane to addicted populations, where infantile longings for magical provision find ready expression. Bion himself traces the proto-mental substrate of the dependency state, showing how its suppression of fight-flight and pairing assumptions confines those alternatives to an undifferentiated physical-psychological matrix. The work-group ideal — in which the dependency leader becomes dependable rather than omnipotent — marks the therapeutic horizon. Crucially, the dependency assumption resonates with wider object-relational and attachment concerns in the corpus: Bowlby's critique of the pejorative use of 'dependence,' Winnicott's account of absolute dependence in early development, and Klein's paranoid-schizoid dynamics all illuminate, from adjacent angles, the psychic territory Bion maps at the group level.
in the basic assumption group, the leader of the dependency group must be omnipotent; the fight-leader must be unbeatable and the flight-leader uncatchable… In the mature work group… the leader of the dependency group is dependable
Flores articulates the structural contrast between the pathological demand for omnipotence in the dependency basic assumption and the more adaptive, realistic leadership of the mature work group.

if the sophisticated group is suffused with the emotions associated with the dependent basic assumption then the flight-fight and pair basic assumptions are confined within the limitations of the proto-mental phase
Bion establishes that the active dependency assumption suppresses the other basic assumptions into the undifferentiated proto-mental system, demonstrating its totalizing dominance over group mental life.

In the dependent group the place of leader may be filled by the history of the group… This record then becomes a 'bible' to which appeal is made… The group resorts to bible-making when threatened with an idea the acceptance of which would entail development
Bion demonstrates how the dependency assumption generates substitute objects for the idealized leader — including texts and traditions — as a defence against growth-demanding ideas.

Gibbon's description of the homoousian controversy was really a report on a therapeutic group session with the dependent basic assumption in action… few things in history have aroused a group's feelings more powerfully than controversy about the characteristics of the deity
Bion grounds the dependency assumption historically, showing that religious controversies about divine attributes are paradigmatic expressions of the group's demand for an omnipotent provider.

the primitive states of mind operating covertly in the basic assumption group tended to dominate the work group and would come to interfere with the declared task of the group
Flores summarizes Bion's core thesis that basic assumption states, including dependency, structurally undermine the overt therapeutic task of any group.

a passive, inactive, and quiet group leader is more likely to provoke Bion's basic assumptions. Basic assumption states owe their existence, therefore, in large part, to the conditions imposed by the group leader
Drawing on Kernberg, Flores argues that the dependency assumption is substantially leader-induced, locating its aetiology partly in the therapist's own behaviour and personality.

Bion's theory (work vs. basic-assumption groups), dependency, 541-542 fight-flight, 542 fusion, 543 leader's influence on basic assumptions, 544-548 pairing, 542-543 stage-specific basic assumptions, 543-544
The index entry confirms the structural architecture of Flores's treatment of Bion's theory, situating dependency as the first of the basic assumptions and linking it to stage-specific group development and leader influence.

when the dependent group is active, is to produce a sub-group which then takes on the function of interpreting the dependent-group leader — usually located in the analyst — to the group
Bion describes a characteristic structural response to the dependency assumption: the formation of an interpretive sub-group that mediates between the idealized leader and the dependent membership.

A group acting on a basic assumption needs no organization or co-operation. The counterpart of co-operation in the basic-assumption group is what I have called valency — a spontaneous, unconscious function of the gregarious quality in the personality of man
Bion distinguishes the work group's organized cooperation from the basic assumption group's automatic valency, clarifying the unconscious mechanism through which dependency states cohere without deliberate structure.

the traditional term 'dependence' has had so baleful an influence. Dependency always carries with it an adverse valuation and tends to be regarded as a characteristic only of the early years and one which ought soon to be grown out of
Bowlby critiques the pejorative framing of dependency in clinical discourse, providing a conceptual counterpoint to Bion's account by rehabilitating healthy dependence as a lifelong attachment phenomenon.

I attribute great force and influence to the work group, which, through its concern with reality, is compelled to… The apparent difference between group psychology and individual psychology is an illusion
Bion affirms the work group's reality-orientation as the counterforce to basic assumption functioning, contextualizing the dependency assumption within his broader individual-group continuum.

What is ordinarily called impatience must therefore, in the basic-assumption group, be considered as an expression of the anxiety which is aroused by phenomena intrinsically co-mingled with a dimension of which basic-assumption mentality knows nothing
Bion reframes impatience as basic-assumption anxiety, illustrating the phenomenological texture of group life dominated by assumptions including dependency.
