A long-term study from Germany suggests a distinct correlation between cognitive ability and political leaning in men, finding that men with higher IQs are less conservative in their political views compared to those with average intelligence.
The research, conducted by psychologists and education experts at Saarland University, indicates that men identified as “highly gifted” are significantly less inclined toward traditional values. Still, the findings highlight a stark gender divide: researchers observed no such correlation between intelligence and political orientation among women.
This discovery is the result of a decades-long observation of individuals’ intellectual and social development, providing a rare glimpse into how cognitive traits may interact with ideological shifts over a lifetime. By tracking a specific cohort from childhood into middle age, the team was able to isolate variables that shorter, cross-sectional studies often miss.
The Marburg Giftedness Project: A 35-Year Timeline
The foundation of these findings lies in the Marburg Giftedness Project, an ambitious longitudinal study that began in the late 1980s. The project initially screened more than 7,000 primary school children during the 1987/1988 school year to identify those with exceptional cognitive abilities.
From that initial pool, approximately 150 children—representing about 2 per cent of the group—were classified as highly gifted. Over the following three decades, 107 of these individuals were monitored closely, alongside a control group of peers with average intelligence, to see how their lives and perspectives evolved.
More than 35 years after the initial testing, the researchers re-engaged with the participants to assess their current political orientations. According to Jorn Sparfeldt, a professor and education researcher at Saarland University, the final analysis included 87 highly gifted adults and 71 adults of average ability, reflecting a response rate of just under 75 per cent.
Measuring Political Orientation and Tradition
To determine the relationship between cognitive ability and ideology, the researchers utilized a detailed questionnaire that asked participants to place themselves on a traditional left-to-right political scale. The survey was designed to move beyond simple party affiliation, focusing instead on deeper ideological leanings across four primary subject areas, including liberalism, and socialism.
The data revealed that for men, higher cognitive ability was linked to a lower adherence to traditional values. In the context of the study, this suggests that gifted men are more likely to question established norms or embrace progressive frameworks than their peers with average intelligence.
The researchers noted that this trend was notably absent in the female participants. This suggests that the drivers of political orientation in women may be influenced by different psychological or social mechanisms, regardless of their IQ score.
Study Participant Breakdown
| Group Category | Number of Respondents | Initial Cohort Size (Gifted) |
|---|---|---|
| Highly Gifted Adults | 87 | ~150 |
| Average Ability Adults | 71 | N/A (Comparison Group) |
| Total Respondents | 158 | — |
Why the Gender Gap Matters
The distinction between men and women in this study is one of its most significant takeaways. While the link between intelligence and a lean toward liberalism is often discussed in general psychological literature, the fact that this specific correlation only appeared in men suggests a complex interaction between gender and cognitive processing.

Psychologist and intelligence researcher Maximilian Krolo, the lead author of the study, emphasized that the lack of these differences among women indicates that cognitive ability does not act as a universal predictor for political leaning. This implies that social conditioning, emotional intelligence, or different educational experiences may play a more dominant role in shaping the political identities of women.
For men, however, the data suggests that high cognitive ability may lead to a greater openness to non-traditional ideas or a higher propensity for analytical skepticism toward conservative structures.
Understanding the Implications
The findings contribute to a broader, ongoing academic debate regarding the relationship between intelligence and ideology. Some researchers argue that higher cognitive ability allows individuals to process complex, contradictory information more effectively, which can lead them away from rigid, traditionalist viewpoints. Others suggest that the environment in which “gifted” individuals are raised—often in academic or intellectual circles—shapes their political views more than their innate IQ.
Because the Marburg Giftedness Project is a longitudinal study, it provides a stronger evidentiary base than a “snapshot” survey. By knowing the intelligence levels of the participants since childhood, the researchers could be more confident that the cognitive traits preceded the political views, rather than the political views being a byproduct of later education alone.
As researchers continue to analyze the data from the Marburg project, the next phase of inquiry will likely focus on the specific “subject areas” where the divergence between gifted and average men was most pronounced, as well as why women remained unaffected by this cognitive trend.
