The article examines the troubling trend of individuals using psychological jargon, such as 'psychopath' and 'gaslighting', as weapons in personal conflicts. By labeling loved ones with these terms, people may feel momentarily justified in their attacks, as seen in the reaction to the work of clinical psychologist Isabel Molinaro, who cautions against this behavior. Such misuse often stems from the widespread accessibility of therapeutic language through social media and the normalization of amateur psychology, resulting in experts even misusing these terms in their practice.

The foundation for these psychological terms is rooted in the 'Diagnostic and Statistical Manual of Mental Disorders' (DSM), published in 1952, which was intended to create a shared language for therapists. Nonetheless, the author points out that the DSM is not exhaustive, acknowledging the complexity of human behavior that cannot be neatly categorized. For example, someone procrastinating is not necessarily suffering from Attention Deficit Hyperactivity Disorder (ADHD), and having bad habits does not equate to a mental disorder.

The book discussed addresses nine psychological terms that are particularly misapplied, such as 'gaslighting', 'obsessive disorder', and 'red flags'. It highlights 'love bombing' as a tactic where the perpetrator inundates the victim with affection before demanding obedience and blind loyalty. This strategy was notably utilized by the Unification Church in the 1970s to lure followers. As readers explore these terms, they are encouraged to discern genuine malice and abuse from ordinary mistakes in relationships, suggesting that recognizing true abuse can be incredibly challenging due to its nuanced nature.
