Cognitive therapy holds that individuals make errors in thinking and that such errors can be corrected in cognitive therapy. The sorts of errors that cognitive therapy can focus on correcting are very straightforward errors to which the correct answers are already basically grasped.
Difficult questions can not be addressed in cognitive therapy. An individual who, for example, is CEO of Widget Corporation has various difficulties that have to be addressed. The cognitive therapist can be of no assistance to the CEO of Widget Corporation as to whether expanding exports is the correct business move, whether building new plants is the correct business move, as to whether the plant floor is a sufficiently safe work environment to work in etc.
Erroneous thoughts are no more prevalent in individuals who are depressed than in individuals who are not depressed. Rather individuals who are depressed can be very insightful.
However, half thoughts can swirl around individuals who are depressed. Cognitive errors in the depressed are half thoughts where such half thoughts are not due to errors in views or to warped emotions but rather such errors are due to various biological strengths that are not sufficiently biologically supported.
Take for example obsessive compulsive disorder. A lot of highly successful individuals have ways of doing things that are unique to such individuals. Individuals with obsessive compulsive disorder more or less have to make every single second unique to such individuals though, of course, strictly speaking every second is already unique to all individuals as time moves forward every second and all individuals are in locations that are unique. Some ‘obsessive behavior’ can be more than acceptable.
Cognitive errors of individuals, half thoughts of individuals, would then be due to individuals having difficulties handling strengths of such individuals. Though far from ridding individuals of all depressions the way to address cognitive errors is for individuals to shun half thoughts, to rather think in sentences and otherwise not silently voice what is amidst situations etc.
