In our most recent survey, Liberals in general were 64% more likely to report major depression, 320% more likely to report bipolar disorder, 50% more likely to report mild depression, and 113% more likely to report Seasonal Affective Disorder.

They were also more likely to use a variety of anti-anxiety and depressive drugs, such as SSRIs (Selective Serotonin Reuptake Inhibitors)--86% more likely, and Anti-anxiety drugs--159% more likely. SNRIs (Selective Norepinephrine Reuptake Inhibitors ) and Tricyclics were also used at a higher rate, but not in significant numbers for either Liberals or Conservatives.

One interesting note, Liberals and Conservatives reported a very high satisfaction rate with the anti-anxiety drugs. SNRIs were also well received, though not as well as the anti-anxiety drug group. SSRIs had mixed reviews, and tricyclics were generally disliked.

On the graph below, we see the major depression breakdown for the Very Conservative (VC), Conservative (C), Liberal (L), and Very Liberal (VL) cohorts.

The above graph shows a stong elevation in the Very Liberals, with the females reporting very high rates of major depression. The Very Liberal males are also the highest on the male scale.

Below, we see the rates of bipolar depression among our political cohorts. Again, we see elevations in the Very Liberals and Liberals, especially the females. Out of the 50 Very Conservative females that responded to our survey, none reported bipolar depression.





Liberals are also elevated in both genders for the most common form of depression---mild depression (see below).

And finally, on the graph below, Liberals of both genders show an elevation in Seasonal Affective Disorder.





This elevated tendency for depressive and anxious disorders is compelling evidence of fundamental differences in the neurophysiological make-up of Liberals and Conservatives. Elevated depression and anxiety rates provide further evidence of a right hemispheric bias in the average Liberal. There is substantial evidence that the right hemisphere is more strongly linked with depressive and anxious disorders than the left.
