Cognitive vulnerabilities take several forms, too. Adults with learning difficulties may find they are more vulnerable than the general population because they cannot always determine when they are being lied to or understand the full value of what they have. Most societies attempt to protect such people and prevent people from abusing their vulnerabilities by scamming them, for example. More widely, psychologists tend to refer to cognitive vulnerabilities as affording certain biases in the minds of people. Stress or maladaptive behaviours can lead to a warped view of the world which – left unchecked – may lead to paranoia, neuroticism or even psychopathy. Some people who have attention deficit disorders may find they fall into the category of having a cognitive vulnerability.
