Good morning, Mr. Siegfried. You studied law and now focus primarily on psychology and speech analysis. How did you come to specialize in this field?

Good morning. Thank you for your inquiry on a subject that I have been deeply engaged with on a daily basis for well over 15 years. My interest in the connection between law, psychology, and speech analysis developed from personal experiences and observations. I repeatedly noticed that certain texts seemed unsettling—their language was exhausting and left a sense of incongruence.

The Roman poet Publilius Syrus already stated in the 1st century BC: "Language is the mirror of the soul: As a person speaks, so is he." This wisdom demonstrates the close link between language and personality.

By employing psychological approaches, primarily through the study of psychopathy, interpersonal dynamics can be analyzed with precision. This allows us to identify which behavioral patterns foster constructive collaboration—and which facilitate conflict or manipulation. My goal is to make these insights applicable for better communication and more effective conflict management.

Which psychological insights are particularly valuable for lawyers in their daily work?

A solid understanding of emotional intelligence, cognitive biases, and manipulative tactics is invaluable for lawyers.

These skills sharpen one’s perception and help clients and their environment better assess situations and address tensions or conflicts more effectively. It becomes particularly challenging when individuals with strong psychopathic traits are involved. They are experts at concealment and manipulation. One example is the so-called DARVO method (Deny, Attack, Reverse Victim and Offender), which such individuals use to provoke judicial errors.

In my book  "Do you speak Psychopath?“  I analyze, among other things, the cases of Horst Arnold and Gustl Mollath. These examples illustrate how manipulative individuals can cause trouble for innocent people, while those involved—from victims to professionals—are often overwhelmed. The key lies in the targeted application of psychological insights to recognize such dynamics early and intervene appropriately.

Although many are aware of manipulative personalities, these individuals still manage to gain power repeatedly. Why is that?

Manipulative personalities masterfully exploit naive or inattentive people through intrigue, charm, and deception. In legal disputes, they often maintain the upper hand through strategic lies and calculated deceptions. A widespread cognitive error is the assumption that the truth lies “somewhere in the middle”—an advantage manipulative people deliberately exploit.

Their “destructive” cognitive dominance allows them to lie, cheat, and manipulate others without moral inhibitions. They lack the typical “guilty conscience” that would hold empathetic people back. - Stephan Siegfried

While empathetic individuals rarely cause harm intentionally, psychopathic individuals exploit these very qualities. Their “destructive” cognitive dominance allows them to lie, cheat, and manipulate others without moral inhibitions. They lack the typical “guilty conscience” that would hold empathetic people back.

However, there are warning signs—so-called "red flags"—that can be identified early. At the  Diversity Academy , we provide practical knowledge to recognize such manipulative patterns and effectively protect oneself from them.

It is known that an above-average number of CEOs exhibit psychopathic traits. How do you assess the situation in law firms?

Similar to leadership positions in major companies, law firms often exhibit characteristics such as self-confidence, risk-taking, and egocentrism at higher-than-average levels. These traits can be valuable skills—for example, in negotiations or asserting interests. However, they also pose significant risks if exercised at the expense of others or if they lead to manipulative behavior.

Kevin Dutton’s Great British Psychopath Survey (2011) revealed that lawyers rank just behind CEOs in the prevalence of psychopathic personality traits. Wherever power, status, and financial incentives dominate, such personalities are more commonly found. This makes it all the more important to understand these dynamics and establish clear values and ethical guidelines to mitigate negative influences.

What preventive measures can organizations take to identify toxic personalities early?

Targeted training for boards, supervisory committees, executives, and HR managers is key. In our workshops—ranging from compact two-hour sessions to intensive full-day seminars—we provide hands-on knowledge about the dynamics of toxic behavior. Using concrete examples, we highlight typical patterns and behaviors.

Participants are often surprised at how cleverly toxic personalities can hide behind a facade of normalcy—often "hidden in plain sight." These trainings enhance awareness and teach strategies to identify problematic personalities early and minimize their impact.

In addition to your work as an author, you are the owner of the  1-prozent GmbH. What services does your company provide?

We offer specialized prevention workshops and targeted interventions to identify toxic personalities in teams early and reduce their influence. Since 2017, we have been using AI-based speech analysis to precisely detect suspicious communication patterns.

Following interventions, we support affected teams with programs to manage the consequences of toxic dynamics. Our focus is on preventing post-traumatic stress disorders and burnout while restoring a healthy and productive work environment.

What signs or language patterns in an application indicate a toxic personality?

In my books (see box), I have thoroughly documented how toxic personalities can be identified through general signs and language patterns. Some typical indicators in applications include:

• Complex sentences with exaggerated or contradictory arguments that may create confusion.
   
• Unnecessary use of technical terms or neologisms to feign competence or impress.
   
• Repetition within the same sentence, suggesting manipulative communication strategies.
   
• Attempts to mimic the recipient’s language style to create sympathy or a sense of belonging.
   
• Frequent grammar and typographical errors, which can indicate carelessness or lack of attention.
   
• Emotional terms used for objects or the opposite, pointing to an unusual emotional processing style.

These signs alone are not definitive proof of a toxic personality but should prompt closer examination of the application.

What legal challenges arise from using language analysis tools in the application process?

As with assessments and aptitude tests, personality and data protection regulations must be adhered to. Results should be communicated transparently and used non-discriminatorily, for example, through "blind" application processes.

This "blinding" should also be applied in conventional application processes. Too often, decisions are still based on gender, age, and appearance rather than qualifications, depending on biases and vested interests of prospective supervisors. Many are familiar with cases like this, as well as instances of nepotism where such issues are overlooked. In these situations, data protection can turn into perpetrator protection, which must be avoided.

How does the use of ChatGPT for resumes and cover letters affect the analysis of written language?

As ChatGPT generates standardized and "polished" texts, warning signs are often concealed. Careful human review remains essential to obtain an authentic picture of the candidates.

What warning signs in the workplace indicate psychopathic traits?

The leading researcher in this field, Robert D. Hare, Ph.D., developed the Psychopathy Checklist (PCL), an instrument for identifying psychopathic traits. The revised version, the PCL-R, was published in 1991 and remains the "gold standard." Initially, it focused on crimes against persons.

To identify psychopathic traits in professional contexts, the B-Scan 360 was developed in the early 2000s based on the PCL-R in collaboration with Paul Babiak and Craig S. Neumann. The criteria help systematically identify toxic behavioral patterns and psychopathic dynamics within corporate structures.

In our workshops, we provide practical insights into recognizing warning signs of psychopathic personality traits in the workplace. These include manipulative communication styles, deliberate deception, and misuse of power positions.

How should lawyers approach working with executives displaying toxic or psychopathic traits?

The first step is to identify these traits early and pinpoint the actual perpetrators. Often, there are accomplices who, as sociopaths, display similarly antisocial patterns. It is essential to recognize that psychopaths are inherently antisocial, while sociopaths develop these tendencies in an antisocial environment.

A clear strategy is crucial: discreet observation, targeted communication, and, if necessary, early escalation to responsible parties.

What else should be noted?

Psychopathy is a severe mental disorder that is both stigmatized and trivialized. Studies indicate that about seven in 1,000 men and three in 1,000 women are affected—roughly 1% of the population. Socially adapted psychopaths are those who, thanks to their manipulative and cunning abilities, can even deceive the justice system. Many operate undetected within society, increasing the likelihood of encountering them. Experience shows that most people have had contact with psychopaths at some point, with many suffering significant physical, economic, or psychological harm.

Despite the challenges posed by psychopathy, it is essential to remember that psychopaths are human. Additionally, even mentally healthy individuals can exhibit behavior resembling psychopathic patterns under certain circumstances. Psychopathy is a continuum that must be understood in all its facets.

This understanding and management of psychopathic behavior patterns are central themes in the workshops offered by the Diversity Academy. The goal is to raise awareness and develop strategies for professional handling of these dynamics.

Thank you for the insightful and educational discussion on this fascinating topic. We wish you continued success!
