The American left and right

Is there a Meaningful Correlation Between Political Ideology and Biological Sex (and Related Hormones)?

One could argue that left-wing is a manifestation of the feminine, and right-wing of the masculine, metaphorically. But, what if its more than just a metaphor?

What if sex steroids like testosterone and estrogen have a direct relation to political identity on an individual and group level (where those who tend toward the male characteristics such as aggression tend toward the right on average, and those with the female characteristics such as compassion tend toward the left on average).

This would explain the historic two-way-ish split in politics, just as sex steroids already explain the two-way-ish split in the sexes (where in both cases there is a roughly binary option with countless in-between positions that exist in a “spectrum” in both sex and politics).

I can’t put this forward as anything more than a loose speculative hypothesis based on armchair reasoning (specifically informal abduction, induction, and deduction). With that said, I’m very confident proper study would show this is a correct and stupidly obvious theory somewhere behind the hypothesis (one that our ancestors have long tried to drill into our heads from their armchairs via myths and stories).

NOTE: Further one could ask, “what if other biological chemicals, for example serotonin, affect political ideology as well?” This, like with hormones, could also help explain why political identity sometimes changes with age. This page is about putting forth these questions, not seeking definite answers.

NOTE: See the citations. There is plenty of studies on or related to this… but I don’t want to point to a study and say “see what they say here,” I want to put this forward as a clear hypothesis based on reasoning alone.[1][2][3][4][5][6][7][8][9][10][11][12][13]

Put simply, what if 1. the right-wing is the embodiment of Mars and the masculine, the left-wing of Venus and the feminine in general and 2. what if this literally relates to sex steroids (androgens and estrogen) and their neurological effects?

In essence, what if sex steroids [at least partly] explain why:

  • The left tends to err toward qualities such as liberty, equality, democracy, sensitivity, fairness, empathy, and related emotions.
  • And, the right tends to err toward qualities such as authority, order, monarchy, honor, rationalism, strength, and related emotions.

TIP: See the image below for more insight into the social and classical left and right.

Here I don’t mean to imply that people are cartoon characters or that the left is never manly or the right has no feminine qualities (I mean, Marx’s beard is pretty is probably a little more manly than Hitler’s well-manicured stache for example; joke).

Rather, I’m imply that this split would represent two pigments would color the complex portraits of people we find in-practice. Where each person is a mix of the masculine and feminine, and each political ideology sees a mix of types under its archetypical umbrella (it isn’t like all the masculine follow one ideology; rather, that quality would just be dominate in the ideology on average and that ideology would be a manifestation of that type).

If that is true, then like with any other fundamental dichotomy, each force is meant to balance each other (just like it is with the genders or any other two forces like this; physical or philosophical).

TIP: The Aristotelian table below will help illustrate what the way in which balance is the key in a two way split:

Sensitivity Insensitive Sensitive Overly Sensitive
Tolerance Intolerant Tolerant Overly Tolerant
Liberty Authoritative Liberal Overly Liberal
Equality Unequal Equal Overly Equal
In-Group / out-Group Individuals Respect for Both Collectives
Sense and Sensibility Logic and Reason (Realism, Sense) Hume’s Fork Empathy and Morality (Idealism, Sensibility)
Teamwork Competition Healthy Competition Cooperation
Progress Traditional Steady Progress Progressive
Strictness Order Principled and lawful Freedom

With the above in mind, one could state logically: An overly maculated or overly feminized society is a society out-of-balance. And likewise, the proper position is the position that ensures balance.

That likely means erring toward the male on some issues and toward the female on others. This DOES NOT mean a totally equal distribution of power or the favoring of on type in general without a well-reasoned justification. It DOES however mean not letting the stronger dominate the weaker in general (where who is the stronger can differ per-issue and with the times).

That also means not demonizing the other political side of the coin any more than you would the opposite gender. What if truly understanding this means WWII with its hyper maculated fascists and feminized communists would have never happened to the degree it did (as trying to destroy the other sex is a fools errand).

What if literally the chemicals our body releases in the process of sexual differentiation and generally throughout life literally shapes our neurology and this has a political effect? It would explain why the two party system seems naturally arising. It would explain many world wars and conflicts, and it would give a half-answer to the solution that wasn’t rooted in political science, but in natural science.

The informal theory (behind the speculative hypothesis) seems so obvious. It is clearly a solid philosophical metaphor (as we have long known), but what if it is actual science? I won’t try to prove it, instead I’ll leave the questions floating in the air and point to more discussion on the topic such as: the left and right are naturally occurring, liberal’s and conservative’s brains are different, the gender spectrum, and the political spectrum.

NOTE: I would argue that people don’t always exhibit the qualities they identify with. Rather, I would assume that people have different reasons for identifying with an ideology. They may seek to protect that group, they may yearn to belong to that group, or they may realize a deficit in their own character and seek balance in the opposite group for example.
