Penile Laterality as a Predictor of Political Orientation

Political ideology has long been studied through the lens of personality, cognition, and socioeconomic circumstance (Jost et al., 2003). Researchers have examined brain structure, cortisol levels, and even disgust sensitivity as biological correlates of political belief (Kanai et al., 2011). Yet one anatomical domain has remained, with baffling and frankly irresponsible neglect, entirely unexplored.

The penis points somewhere. It has always pointed somewhere. No published study has asked where, or why, or whether the direction it points tells us something profound about the society in which it exists. This is a catastrophic gap in the literature. The present study addresses this gap directly, rigorously, and without apology. We propose that penile resting laterality — the direction of natural deflection in the unstimulated state — is a stable, measurable, and politically meaningful anatomical trait (Flessner & Pudney, 2023).

Participants. 312 male-identifying adults aged 18–67 were recruited via community poster and one highly specific subreddit. Participants who identified as libertarian were excluded because their laterality data pointed in three directions simultaneously. Scrum Masters were excluded due to conflict of interest. Final N = 271.

Instruments. Political orientation was assessed using the Ideological Positioning and Anatomical Narrative Survey (IPANS; α = .91). Penile resting angle was measured using the Deflection Orientation Recording Device (DORD), a protractor mounted on a very understanding research assistant.

Procedure. Participants were assessed in a private booth. The control group was given no political information and no explanation for anything, consistent with standard institutional practice.

Ethics. Approved by the IRB under protocol number GT-69-RIGHT-2023. All participants consented. Most seemed fine.

Primary Finding: Rightward Deflection and Right-Wing Alignment. A strong positive correlation was observed between rightward penile angle and self-reported right-wing orientation (r = .74, p < .001, d = 1.31). Participants scoring above 7 on the IPANS Conservative Subscale exhibited a mean rightward deflection of 23.4°. This is, statistically speaking, a lot.

Secondary Finding: Leftward Deflection and Progressive Identity. Left-identifying participants showed significant leftward deflection (t(269) = 9.83, p < .001, η² = 0.26). The effect size was described by one co-author as "frankly upsetting in its clarity."

Tertiary Finding: The Centrist Null Result. Self-described centrists produced a mean deflection of 0.3°, F(2, 268) = 44.1, p < .001. They are, anatomically, going nowhere.

These results are the most important findings in political biology since the discovery that conservatives have stronger startle responses, a fact which has also never been used responsibly. The correlation between penile laterality and political orientation was robust across age, education, and whether the participant drove a truck.

We propose the Flessner-Pudney Law of Ideological Deflection: in any population of sufficient size, the body will physically orient itself toward its political convictions. This is analogous to gravitropism in plants, except that plants do not vote and, frankly, seem better governed.

The primary limitation of this study is that it was conducted entirely on humans. Future research should include other mammals, particularly those who attend local council meetings.

The centrist null result is, in the opinion of the authors, personally devastating and entirely expected.

Penile laterality is a stable, measurable correlate of political identity and should be incorporated into electoral demographic modelling immediately. We call on governing bodies, polling institutions, and trouser manufacturers to act on these findings. The data are clear. The direction is set. The time is now.
