Increased gullibility makes a person vulnerable to manipulations. The gullible people are often victims of scams or frauds. Scam crimes are a significant problem in civil justice procedures and criminal investigations.The repercussion of gullibility can be especially seen among older people. Elderly people seem particularly vulnerable to scam .Thus, the frequency and intensity of gullibility and the ways to assess this vulnerability are in particular a problem in the field of geriatric care and in general in care for the well-being of elderly people .Surprisingly, so far, almost no scientific studies have been attempted to assess the degree of dependence between the age of patients and intensity of gullibility. Also, the factors that influence the existence of this particular personality trait have not been examined yet extensively.
