““Although relatively speaking the right hemisphere takes a more pessimistic view of the self, it is also more realistic about it.457 There is evidence that (a) those who are somewhat depressed are more realistic, including in self-evaluation; and, see above, that (b) depression is (often) a condition of relative hemisphere asymmetry, favouring the right hemisphere.458 Even schizophrenics have more insight into their condition in proportion to the degree that they have depressive symptoms.459 The evidence is that this is not because insight makes you depressed, but because being depressed gives you insight.””
