How the brain structures the boundaries of psychiatric discourse

Area of Science:

• Psychiatry
• Neuroscience
• Philosophy of Science
• Sociology of Science

Background:

• Psychiatry historically utilizes the brain as a core explanatory model and source of legitimacy.
• The persistent reliance on the brain in psychiatric discourse extends beyond mere neuroscientific advancements.
• Conceptual fragmentation and uncertainty characterize the field of psychiatry.

Purpose of the Study:

• To explore the function of "brain talk" as a metaphorical and organizational device in psychiatric discourse.
• To analyze how the brain serves as a boundary object and conceptual metaphor within psychiatry.
• To understand how cerebral metaphors contribute to psychiatry's identity, coherence, and legitimacy.

Main Methods:

• Conceptual analysis drawing on theories of boundary objects and conceptual metaphors.
• Examination of psychiatric discourse and its reliance on brain-centric language.
• Exploration of the role of metaphor in scientific fields facing epistemic uncertainty.

Main Results:

• The brain functions as a boundary object, providing a shared referent for diverse psychiatric communities (clinicians, researchers, patients).
• The brain operates as a conceptual metaphor, generating intelligible and resonant narratives for psychiatric knowledge, even with opaque mechanisms.
• Cerebral metaphors facilitate psychiatry's self-organization as a pluralistic field, balancing scientific aspirations with epistemic humility.

Conclusions:

• The power of "brain talk" in psychiatry reflects its function in stabilizing the field's identity and legitimacy.
• The brain metaphor serves as an epistemic anchor, enabling psychiatric coherence amidst conceptual fragmentation.
• Metaphorical reliance on the brain highlights psychiatry's ongoing efforts to navigate scientific uncertainty and cultural relevance.
