Chapter 1: The Mensa Study and Its Findings
In recent explorations of mental health, the question arises: Do individuals with elevated IQs experience higher rates of depression? The Mensa Study suggests a noteworthy correlation.

My previous article delved into the relationship between writing and depression, reflecting on how my own mental health has influenced my creative process. During my research, I stumbled upon the intriguing notion that a higher IQ might be linked to depression.
Although connecting writing to depression was a significant leap for me, the idea that intelligence—a fundamental aspect of our identity—could contribute to mental illness raises essential questions. How might one substantiate this potential link?
Section 1.1: Understanding Mensa's Role
Mensa, renowned as the largest and oldest high IQ society globally, admits members who score in the top 2% of IQ tests, equating to an IQ of 132 or above, compared to the average score of 100. With around 134,000 members, their headquarters is located in Caythorpe, UK.
Researchers Ruth Karpinski and her team seized the opportunity to investigate this high IQ society to assess the rumored association between elevated IQ and mood disorders. They administered a comprehensive survey covering various psychological conditions, including mood disorders (like dysthymia, bipolar disorder, and depression), anxiety disorders (social, generalized, and obsessive-compulsive), autism, and ADHD.
The survey also included questions regarding non-psychological health issues, such as environmental allergies, autoimmune disorders, and asthma. Respondents reported whether they had received formal diagnoses or suspected they had any of these conditions. This aspect is particularly significant.
Firstly, the stigma surrounding mental illness often prevents people from seeking help or receiving formal diagnoses. Additionally, some may experience depression without ever reaching out for assistance, which, while not ideal, does occur. The absence of a formal diagnosis does not diminish the seriousness of a condition. Conversely, one could argue whether individuals, especially those confident in their intelligence, might overestimate their ability to self-diagnose or misinterpret symptoms that wouldn’t meet clinical criteria.
Section 1.2: Survey Results and Implications
The survey achieved an impressive return rate of nearly 75%, which is remarkable for this type of data collection. Karpinski et al. compared the responses of 3,715 participants against national averages. They discovered significant disparities in mood and anxiety disorders, with 26.7% of respondents reporting formal mood disorder diagnoses and 20% for anxiety disorders.
In contrast, the national averages for these categories sit at approximately 10%. Other conditions were also reported more frequently, though the differences were less pronounced. Notably, environmental allergies were reported by 33% of respondents—over three times the national average of 11%. This finding may align with stereotypes regarding intelligence and allergies.
Chapter 2: Theoretical Frameworks
The first video, "4 Reasons Highly Intelligent People Tend To Be Depressed," explores the various factors contributing to this phenomenon.
Karpinski and her colleagues proposed the hyper brain/hyper body theory, suggesting that high intelligence may be accompanied by heightened psychological and physiological responses. "Overexcitabilities," characterized by intense reactions to environmental stimuli, can lead to both physiological stress responses and psychological tendencies to ruminate.
Consider a common scenario, such as receiving criticism from a supervisor. The hypothesis is that a highly intelligent individual might dwell on the negative feedback, worrying about future implications, while someone with a lower IQ may move on more readily. Such patterns could foster environments conducive to anxiety and depression.
Additionally, those with higher IQs may be more prone to contemplate societal and global issues, potentially leading to feelings of 'weltschmerz' regarding the world's imperfections. This emotional weight can significantly impact one's mental well-being.
Furthermore, some research suggests a correlation between introversion and higher IQ, which could contribute to social anxiety. However, this remains to be conclusively determined, as both introverts and extroverts can experience mental health challenges.
The second video, "6 Struggles of Being Overly Intelligent," highlights the unique challenges faced by individuals with high IQs.
Section 2.1: Why It Matters
Understanding the potential links between intelligence and mental health is vital for psychologists aiming to unravel the complexities of disorders like depression. If a genetic component related to high IQ also predisposes individuals to depression, it may provide insights for screening and targeted interventions.
Conversely, if environmental factors contribute to this correlation, it highlights the importance of addressing key risks in upbringing and lifestyle choices. Each discovery enhances our understanding of depression, bringing us closer to demystifying its causes.
Section 2.2: Limitations of the Study
However, this study alone cannot establish a definitive link between high IQ and mental illness. It is crucial to note that correlation does not imply causation. Members of Mensa may share traits beyond just high IQ; they might engage in more intellectual pursuits and have less social interaction, both of which can affect mental health.
Moreover, we must consider whether the elevated rates of mental illnesses in this demographic are due to heightened awareness and willingness to seek diagnoses, rather than an actual increase in prevalence. Individuals with lower IQs may not recognize their symptoms or label them as mental health disorders.
Conclusion: A Complex Picture
While the Mensa study presents intriguing findings, it raises more questions than answers regarding the relationship between high IQ and depression. The multitude of variables involved complicates any straightforward conclusions. There is a risk in oversimplifying mental health issues by attributing them to a single trait.
By associating intelligence with mental illness, we may inadvertently romanticize the concept, perpetuating stereotypes of the "tortured genius." Mental health conditions arise from a complex interplay of biological and environmental factors. Reducing them to a single cause oversimplifies the issue and undermines individual struggles.
As we continue to study the connections between traits like intelligence and mental illness, we must acknowledge the inherent limitations of our findings. Each case is unique, and while research such as the Mensa study can provide valuable insights, we should remain cautious about generalizations.
