Another point to be considered while analyzing the role of brand trust on purchasing
decisions is the double jeopardy effect stated by Ehrenberg et al. (1990). Trust in a brand
with high visibility in the market, being one that is highly recognized and enjoys a high

rate of sales, will be higher, and with this trust, new sales will be realized. This cyclical
situation raises the question of whether brand trust should be evaluated in purchasing
decisions as a differentiation tool or as a hygiene factor. Romaniuk and Bogomolova
(2005) stated in their study that trust in brands with a high market share is also high, and
that individuals may display a tendency to trust the brands they see most often and that
they observe being purchased often.
