Their maybe some real truth to that statement - although I realise this might be satire - The diathesis stress model for the aetiology of psychological disorders as well as other psychosocial contributions could be an indication that external environmental forces as opposed to primarily just internal causes (or vulnerabilities) could elude to just that. Everyone is right inside their own mind. The point is - no one outside of ourselves can be right about anyone or really question how another persons mind may work or what constitutes as accurate thinking or not - which is why, as I have discovered, helping people is a lot more than adjusting what may be perceived as inaccurate cognitive processes and more about appeasing and adjusting to an individuals personal distress, taking into account their background, culture, social status and other aspects of their life. Helping them to learn new skills and coping mechanisms in a way that they respond to in the most personal productive and positive way. People get angry and have often been confrontational (and sometimes violent) with me when I have tried to tell them that their thinking is wrong (whether it may be or not) or that their feelings should be discounted or marginalized due to any flawed understandings of the world around them.
