Frank Costello: The Prime Minister of the Underworld and the Art of Soft Manipulation
Francesco Castiglia, become Frank Costello (1891-1973), exercised power principally through political corruption and persuasion rather than violence. His profile is all the more fascinating as it constitutes one of the rare documented cases of a mafia chief voluntarily undertaking psychotherapy.
In the article that follows, I draw the psychological portrait of this figure. Reading a life this way often raises the same question about oneself: I designed a test to assess whether you're in a manipulation situation that helps you take stock of the control mechanisms at play around you. It comes with a guide to extend your reflection beyond the results. I also wrote a book on this subject, Breaking Free from Toxic Relationships, if you would like to go further.
Immigration and Founding Shame
The name change from Castiglia to Costello was a symbolic erasure of shameful origin — a Young imperfection/shame schema. He worked his entire life to eliminate his Italian accent and adopt elite American codes. This permanent identity performance required considerable psychic effort. You can also discuss this in Psy Lounge, a voice space run by a CBT-trained AI.
Social Intelligence as Weapon of Choice
Costello systematically preferred seduction over manipulation by violence. This reveals exceptional social intelligence — theory of mind: the capacity to understand others' motivations with remarkable precision. Behind this social mastery lay a preoccupied anxious attachment style. By making himself indispensable to dozens of political and judicial personalities, Costello created a system where others depended on him — inverting his attachment schema dynamic. I examine this question in The Narcissistic Abuser.
Costello's Psychotherapy: Exceptional Lucidity
In the 1950s, Costello consulted psychiatrist Richard H. Hoffmann for several years — absolutely remarkable in mafia context. This reveals an introspective capacity rare in antisocial personalities and cognitive flexibility enabling him to transcend his milieu's norms. He likely suffered from chronic anxiety, sleep disturbances, and depressive symptoms.
The Kefauver Hearings: The Mask and the Hands
During the 1951 televised hearings, Costello's nervously fidgeting hands expressed what his controlled face strove to conceal: intense anxiety. The body, as always, did not lie. This dissociation between verbal control and somatic agitation characterizes the adaptive social mask.

Is soft manipulation always a sign of psychopathy?
No. Manipulation and social charm can be the survival strategy of an anxious personality in a hostile environment. This distinction is clinically crucial: while psychopathy is largely treatment-resistant, anxiety-driven soft manipulation is perfectly accessible to CBT.
Book an appointmentIn short: Frank Costello represents a unique psychological case: the mobster who preferred soft manipulation to violence, political power to physical terror, and who — unprecedentedly — consulted a psychiatrist for years. Behind the flattering nickname "Prime Minister of the Underworld" lay a man profoundly marked by shame of his poor Italian origins, anxious attachment compensated by accumulation of political power, and exceptionally refined social intelligence enabling him to seduce senators and mafia chiefs alike. His recourse to psychotherapy reveals a lucidity about his own suffering that most criminal figures do not possess.
