The psychology of human misjudgment is a fascinating topic that can help us understand why we make certain decisions and how we can avoid common pitfalls. One of the most common misjudgments is confirmation bias, which is the tendency to seek out information that confirms our existing beliefs and ignore information that contradicts them. This can lead to a distorted view of reality and prevent us from considering alternative perspectives.

Another common misjudgment is the halo effect, which is the tendency to judge a person's character based on a single trait or characteristic. For example, if we find someone physically attractive, we may assume that they are also intelligent, kind, and trustworthy, even if we have no evidence to support these assumptions. This can lead to inaccurate judgments and unfair treatment of others.

Cotard's Syndrome, also known as Cotard's Delusion or Walking Corpse Syndrome, is a rare mental disorder that affects a person's belief about their existence. The affected person holds a delusional belief that they are dead, do not exist, are putrefying, or have lost their blood or internal organs. This disorder is named after the French neurologist Jules Cotard, who first described it in 1880 as 'the delirium of negation.'

Cotard's Syndrome is a complex disorder that can present in different ways. Statistical analysis of a hundred-patient cohort indicated that denial of self-existence is present in 45% of the cases of Cotard's Syndrome, while the other 55% of the patients presented with delusions of immortality. A mild case is characterized by despair and self-loathing, while a severe case is characterized by intense delusions of negation and chronic psychiatric depression.
