Dr. Samenow and Dr. Yochelson conducted a 14-year study with 255 criminal participants to develop an understanding of criminal thinking patterns. Their research challenged the prevailing view that environmental factors like poverty or abuse cause crime, finding that individuals make choices in how they respond to their environment. The study identified common thought patterns of criminals, including being restless and dissatisfied, feeling no obligation to others, and seeking excitement at any cost. It also found that focusing treatment on identifying and challenging criminal thinking errors can positively impact offenders.
