Thoughts that arise spontaneously when humans are not deliberately trying to think of something are known to play a key role in decision-making and various cognitive functions, as well as in some mental health disorders. In fact, psychology studies suggest that individuals diagnosed with various psychopathological disorders, including depression and anxiety disorders, can experience maladaptive spontaneous thought patterns, such as overthinking or obsessing over specific things, catastrophizing and ruminating about aspects of life that are challenging or painful.
