Personality Dysfunction Revealed Through Everyday Word Use
Is it possible to spot personality dysfunction from someone’s everyday word use? Recent research suggests that it is indeed possible, and often sooner than one might expect. Words people choose in various forms of communication, such as text messages, emails, chats, or online comments, can quietly reveal deeper patterns in how they think, feel, and relate to others.
Personality traits are habitual ways of thinking, feeling, and behaving that everyone possesses. When these patterns become rigid, intense, or disruptive, they can lead to ongoing issues with emotions, sense of self, and relationships. At the more severe end of the spectrum are personality disorders, where these patterns cause significant distress and impairment. Common personality disorders include narcissistic, antisocial, and borderline personality disorder.
However, not everyone has a full-blown disorder, as personality functioning exists on a spectrum. Many individuals may exhibit milder difficulties, such as mood fluctuations, negativity, rigid thinking, or darker traits like manipulation and callousness. These patterns often manifest in how people speak or write before they become evident in more explicit behavior.
Linguistic analysis of individuals with severe personality dysfunction, such as Austrian serial killer Jack Unterweger and Dennis Rader, the BTK killer, has revealed distinct language patterns. For example, individuals with darker personality traits tend to use more hostile, negative, and disconnected language, including swear words and anger words, while using fewer socially connected terms.
Research studies using computational text analysis have shown clear evidence that personality dysfunction leaves a detectable trace in everyday communication. In one study published in the Journal of Personality Disorders, individuals with greater personality dysfunction used language that conveyed a sense of urgency, self-focus, and negativity in essays about close relationships.
Another study published in the Journal of Affective Disorders Reports found that individuals with more dysfunctional or disordered personalities used more negative emotion words in both written essays and transcribed conversations. They exhibited a preoccupation with negative feelings, even during mundane interactions.
Analyzing nearly 67,000 Reddit posts from individuals who self-identified as having a personality disorder in a study published in npj Mental Health Research revealed that those who frequently engaged in self-harm used markedly more negative and constricted language. Their posts contained more self-focused language, negations, sadness, anger terms, and swearing, reflecting emotional overwhelm, negativity, withdrawal, and rigid thinking.
Analyzing over 830,000 posts from individuals with personality disorders and a general-population comparison group in an ongoing project showed that individuals with personality disorders shared self-beliefs online more frequently. Their self-beliefs were more negative, extreme, and disorder-focused, centering on pain, trauma, and negative emotions.
Understanding these linguistic patterns can provide valuable insights into someone’s emotional world, identity, thinking patterns, and relationships. Noticing shifts in language patterns can help identify early red flags and navigate social interactions with greater awareness.
In conclusion, subtle linguistic traces in everyday word use can offer a window into someone’s emotional well-being and relationships before they openly express their difficulties. Recognizing these patterns can help us understand others, support those who may be struggling, and navigate our social lives with greater awareness both online and offline.
