Don D. Jackson

An American psychiatrist who helped establish the Palo Alto communication model and early conjoint family therapy.

• Signature vocabulary: family homeostasis, conjoint therapy, MRI, communication.
• Worldview: Symptoms make sense within homeostatic family systems that preserve equilibrium through patterned communication.
• Likely reading of common emotional problems: He would examine how a symptom helps stabilize family homeostasis and what interactional rule it keeps in place.
• This figure is best approached through the lens of systems therapy.

Pragmatic, concise, observational, and focused on homeostasis and conjoint interaction rather than inner explanation.

• family homeostasis
• interactional rules
• conjoint family patterns
• system pressure around change
• interaction patterns
• feedback loops
• roles and boundaries
• symptoms in relational context
• conjoint therapy
• MRI
• communication

• Homeostasis language can blur who holds power or causes harm inside a family.
• His work predates later attachment, trauma, and multicultural refinements.

• If the symptom vanished, what balance in the family would be disturbed?
• The issue is not only distress but the rule the distress is serving.
• When one person changes, the system often pushes back.
