We like to joke about liberals having Trump Derangement Syndrome. Well, most people joke about it, I think it’s true that they really do suffer from a mental illness that makes them go crazy when it comes to anything related to President Trump.

Now a new study has proven that the group of people who have the largest number of mental illnesses just happens to be liberals.

Zach Goldberg, a Ph.D student did a deep dive into some data and found that liberals are much more likely to have a mental illness that those that are conservative.

Take a look at these charts:

Notice in those charts that almost half of white liberals under the age of 29 claims to have been diagnosed by a doctor that they have a mental health condition.

The entire paper is available for download, but here’s the abstract:

It has been claimed that left-wingers or liberals (US sense) tend to be more mentally ill than right-wingers or conservatives. This potential link was investigated using the General Social Survey. A search found 5 items measuring one’s own mental illness in different ways (e.g.”Do you have any emotional or mental disability?”). All of these items were associated with left-wing political ideology as measured by self-report. These results held up mostly in regressions that adjusted for age, sex, and race. For the variable with the most data, the difference in mental illness between “extremely liberal” and “extremely conservative” was 0.39 d. This finding is congruent with numerous findings based on related constructs.

When you also take a look at the chart above you’ll notice that on every level on the side of this liberalism spectrum, every single level of liberalism has a higher rate of mental illness than every single level of the conservative side of the spectrum.

Frankly, this is no surprise to me at all.
