Abstract:

The aim of the study was to weigh the behavioral biases of commercial bank and participation bank customers in Turkey in order of significance and to reveal whether there is a difference in behavioral biases of individuals. The questionnaire form prepared in this context was delivered to the individuals and the data obtained were evaluated using the fuzzy Analytical Hierarchy Process (AHP) method. As a result of the study, it was found that the three most effective main criteria for commercial bank customers are overconfidence, representation, and herding biases. The most important biases for the participation bank customers were determined as conservatism, overconfidence, and representation biases. Overconfidence, conservatism, and representation biases were determined as important for customers who prefer both commercial and participation banks in banking transactions. The results show that there are differences between the biases exhibited by individuals who transacted in different types of banking.
