Many professionals have encountered difficult colleagues who seem to relish manipulation, deception and a complete disregard for others’ feelings. But distinguishing between an unpleasant coworker and someone exhibiting genuine psychopathic traits can be challenging. Geraint Anderson, a former London banker turned author, has openly discussed his own journey with behavioural adaptation in high-pressure financial environments, revealing how certain traits rewarded by modern workplaces can mirror those associated with psychopathy.
The Corporate Culture That Rewards Ruthlessness
Anderson spent 12 years climbing the ranks as an analyst in London’s financial district, earning millions before exiting ahead of the 2008 crash. He now lives in Monmouthshire and reflects on how the city’s cut-throat atmosphere demanded a transformation of his personality.
“I had to really become a kind of worse version of myself in order to thrive in this environment,” Anderson admitted. His adaptation included drastic changes – cutting his ponytail, shaving his beard, removing his earrings and purchasing a £60 suit the night before his interview. Success became an obsession, with bonuses serving as “a way of gauging how wonderfully successful a human being I was.”
The former City boy explains that certain psychopathic traits align perfectly with what corporate environments value: “uber confidence, ability to control and manipulate others, not getting emotionally involved in decisions and being decisive.” He believes the financial sector actively rewards these characteristics, creating a culture where individuals may feel compelled to adopt darker aspects of their personality to succeed.
Understanding Psychopathic Traits in Professional Settings
A psychopathy, clinically known as an antisocial personality disorder, involves distinct patterns of thinking and behaving that differ significantly from most people. These individuals often exploit others without remorse, struggle with long-term relationships, and exhibit poor impulse control.

Robert Snowden, a psychologist at Cardiff University with 25 years of experience studying psychopathy, collaborates with Robert Hare, creator of the widely-used psychopathy checklist (PCL-R). This 20-question assessment scores individuals between zero and two, with 40 representing the maximum possible score.
Snowden notes that most people score below five on this scale, while scores above 25 typically indicate psychopathy. Anderson assessed himself at approximately eight or nine – placing him in a borderline category according to traditional standards.
“Psychopathy is on a dimension that I could place you, I could place myself,” Snowden explained. He acknowledges that while psychopaths rarely commit violent crimes, they frequently exploit others without empathy or remorse. “They can be very strong and, in some ways, make good leaders… but there are many deficits to their leadership and it’s all about them and not about other people,” he added.
The Verdict: Situational Adaptation vs. Clinical Diagnosis
Despite his self-assessment, Anderson recently underwent evaluation by consultant and forensic psychologist Kerry Daynes, who concluded he does not meet criteria for psychopathy. Instead, Daynes diagnosed him with “situational psychopathy” – adapting behaviour to thrive in environments that reward ruthless ambition.
Daynes emphasised that Anderson didn’t need to be a clinical psychopath to succeed temporarily in what she described as “a psychopathic culture.” His ability to “crank up” his darker personality characteristics placed him in the “sweet spot that most people can’t attain.”
However, Anderson grew increasingly disillusioned with the industry’s culture of greed, reckless risk-taking and rule-breaking. “I just looked around and thought ‘I’m on the wrong team’… What on Earth are you doing? You are part of the problem,” he reflected.
This epiphany led him to abandon his corporate persona and become the anonymous columnist “City Boy” for a London newspaper, exposing the excesses of the financial world through tales of lavish entertaining, drug use and illicit affairs. His revelations became the bestselling book Cityboy, selling over 400,000 copies across six languages.
Recognising Dangerous Behaviour Patterns
Identifying psychopathic traits in the workplace requires attention to consistent behaviour patterns rather than isolated incidents. Key warning signs include:

- Exploitation without empathy: Using others for personal gain while showing little concern for their wellbeing
- Lack of genuine remorse: Offering superficial apologies while continuing harmful behaviour
- Inconsistent narratives: Frequently changing stories to suit circumstances
- Superficial charm: Displaying charisma that feels rehearsed or manipulative
- Blaming others: Attributing failures to external factors rather than accepting responsibility
Anderson’s experience demonstrates that success in certain corporate environments doesn’t necessarily indicate clinical psychopathy. However, it does suggest that organisations must critically examine what behaviours they’re incentivising and whether those practices contribute to long-term sustainability and ethical standards.
Currently, there is no effective treatment for psychopathy, largely because individuals with the condition often believe their behaviour is perfectly normal. This reality underscores the importance of prevention through organisational culture rather than remediation after the fact.
Why it Matters
The distinction between high-performing professionals who adapt to demanding environments and those displaying genuine psychopathic traits has profound implications for workplace safety and organisational culture. When companies inadvertently reward manipulative, remorseless behaviour through promotion, bonuses or recognition, they create environments where such traits flourish – potentially leading to ethical breaches, toxic cultures and ultimately business failure. Understanding these dynamics is crucial for developing leadership programmes that prioritise emotional intelligence, empathy and genuine collaboration alongside performance metrics. As Anderson’s transformation from ruthless City trader to conscientious author demonstrates, individuals and organisations alike can choose to build cultures based on authentic success rather than psychopathic survival tactics.
