Leftism as a Global Mental Disorder, By Brian Simpson
Emil Kirkegaard's recent Substack piece, "Leftism, mental health, and visual presentation confirmed," presents fresh evidence from a study he co-authored showing a consistent negative relationship between Left-wing political ideology and multiple measures of mental health. In a representative sample of nearly 1,000 American adults, researchers found that stronger identification with Leftist views — across a detailed 41-item scale — correlated with higher rates of diagnosed mental health conditions, more recent psychological symptoms, lower life satisfaction, and broader indicators of psychopathology. These associations held up even after careful statistical checks for measurement bias, suggesting the link is not simply an artifact of Left-leaning people being more open about their struggles or more likely to seek therapy.
The pattern is far from new. A substantial body of research stretching back years has repeatedly documented that individuals on the political left tend to report higher levels of depression, anxiety, and other internalising disorders compared to moderates or conservatives. The gap often becomes most pronounced among those who describe themselves as "extremely liberal," and it appears especially sharp among younger women. Conservatives, by contrast, consistently score higher on measures of life satisfaction and self-reported happiness, even when researchers control for factors like income, education, and age. Personality traits play a role here too: Leftism tends to align with higher neuroticism — a predisposition toward negative emotions, rumination, and anxiety — along with greater openness to experience. Conservatism more often correlates with emotional stability and conscientiousness.
Kirkegaard's study adds weight to this literature by demonstrating that mental health diagnoses remain a strong predictor of Leftist ideology even in multivariate models. It also highlights striking visual and behavioural markers: things like unnatural hair colors, certain piercings (particularly septum or more extreme placements), and visible tattoos show strong associations with both Left-wing views and poorer mental health. These signals appear to function almost as outward expressions of the underlying psychological patterns.
Erich Fromm's The Sane Society is particularly pointed in this context. Fromm argued that a healthy society must fulfill fundamental human needs for meaningful work, love, freedom, rootedness, and a coherent sense of identity. He warned that even outwardly functioning societies could produce widespread alienation and pathology if they failed to meet these deeper requirements — what he called a kind of "folie à millions," where shared societal flaws are mistaken for normalcy. In Fromm's view, a genuinely sane individual might actually appear maladjusted within a deeply unhealthy cultural environment.
Applying that lens today, the dominance of Left-leaning perspectives across major Western institutions — academia, media, education, NGOs, human resources, and much of the cultural elite — creates an interesting inversion. Rather than producing the psychologically flourishing society Fromm hoped for, we appear to be living through something closer to an "insane society." When institutional power tilts heavily toward worldviews that emphasize perpetual systemic crisis, identity-based grievance, deconstruction of traditional structures, and a constant sense of moral urgency without strong counterbalancing narratives of agency, resilience, or rootedness, the result can amplify traits linked to distress and rumination. The data suggest that this ideological environment may not only attract individuals already higher in neuroticism, but could also actively shape cultural norms in ways that make psychological fragility more common and even normalised.
Of course, the direction of causation remains complex and hotly debated. It could run both ways: people prone to anxiety and rumination may gravitate toward ideologies that frame the world as fundamentally unjust and in need of constant intervention. At the same time, once those ideologies achieve institutional dominance, they may foster environments where rumination on societal ills is rewarded while stoicism, tradition, or personal responsibility are downplayed. Additional factors like social media amplification, family breakdown, and technological changes clearly play roles in the broader youth mental health crisis, but the ideological component appears difficult to dismiss given the persistent correlations.
In the end, Kirkegaard's essay and the wider research point to a sobering possibility: heavy Left-wing influence over the idea-shaping institutions of Western societies has not delivered a saner or more mentally healthy population. Instead, it may be contributing to feedback loops where vulnerability and distress become more widespread. This does not mean every Leftist is mentally unwell or that conservatives are immune to modern pressures — far from it. But the patterns are consistent enough that treating them as mere coincidence or reporting bias risks missing deeper cultural dynamics at work.
