# Do cognitive distortions not exist at all in non-depressed people?

Cognitive distortions like All-or-nothing thinking, Fortune Teller Error; do they exist in non-depressed people with a low intensity as well or they do not have these things at all? In other way, having cognitive distortions is the root cause of depression or having those distortions with high intensity is actually the root cause of depression?

• It is not clear whether you are making a statement that, or asking whether, cognitive distortions are the root cause of depression. Depression comes in many forms and surely many causes. Lumping it all together in one cause is likely a bad approach. Also, assuming that all forms of depression have the mentioned features is asking for problems. Also, I am pretty sure that various distortions exist in many persons not considered depressed. Humans are not perfect, even when they try to be. – Michael Dec 15 '15 at 20:35
• @Michael You kinda answered my question. All I'm asking is that cognitive distortions exist in all people with various amount of intensities? – Arslan Ali Dec 16 '15 at 13:54
• While I may not have official evidence to back up the statement, I am nearly positive that cognitive distortions exist in nearly everyone to varying degrees. I am also under the impression that some people with depression may have less cognitive distortion on various topics. There are many hopeless problems in this world for which there is no solution in sight, and the happiest thing to do is to ignore these problems. Might is right is a common saying that highlights the idea that history is inaccurately re-written by the those with the most power, regardless of morality or truth. – Michael Dec 16 '15 at 17:59
• Another key point to consider is that depressed persons may have troubled thinking as a result of their depression, but this does not mean that the person's thinking before becoming depressed had anything distorted or illogical about it. It would be a folly to blame the result of depression for being the cause of depression. For example, if a person got in an auto accident and ended up with motor problems, would it be correct to blame the accident on these motor problems that resulted from the accident? – Michael Dec 16 '15 at 18:04
• Elaborating on Michael's first point - a good idea would be to research 'depressive realism' and concerned experiments. It holds that in some cases, depressed persons can make more accurate inferences then their non-depressed counterparts. However, these rose-tinted glass that non-depressed people see through are evolutionary adaptive. Take a hypothetical example of getting into a program with a 5% acceptence rate - a depressed person may accurately predict that he or she is not likely to get in. However, the "deluded" positive person will attempt to make the cut although sucess is unlikely. – Vakalate Dec 17 '15 at 1:13
