One strength of the cognitive explination of depression is that there is research to support from Boury that depressed people are more likely to misinterpret negatively highlighting that there is evidence of cognitive bias’ in depressed people extorting reality. Furthermore, they felt hopeless about their future which supports the negative triad (becks research) which links self, world (negative misinterpretations) and future (hopeless).
