Your Literature Professor Says, "The Great Russian Authors Engaged in a Lot

Your literature professor says, "The great Russian authors engaged in a lot of self-reflection.That is why they were all depressed." Is this statement true? Why or why not?

A) Yes, research shows that Russians engage in more self-reflection than North Americans and that this high level of self-reflection is associated with greater depression.
B) No, research shows that self-reflection is associated with greater depression among North Americans but not Russians.
C) No, research shows that self-criticism, but not self-reflection, is associated with greater depressive symptoms among Russians.
D) It depends; research shows that, for Russians, greater self-reflection is related to more depression, but only among Russians who have a strong distrust of others.
E) It depends; research shows that, for Russians, greater self-reflection is related to more depression but only when they reflect on negative aspects of the self.
