When discussing ADHD and intelligence, the conversation is often distorted by outdated assumptions and narrow measures like IQ tests. While some studies suggest that individuals with ADHD show differences in certain cognitive areas, these findings are based on neurotypical standards that don’t capture the unique abilities of ADHD brains. Worse, these results have been used to stigmatize and exclude ADHD individuals, especially in academic and professional settings.
New research is pushing back against these outdated frameworks, showing that ADHD brains operate differently—but not less intelligently. Let’s explore what the science says, how it’s been misused, and why it’s time to rethink intelligence itself.
What Does the Research Say?
Several studies have examined the connections between ADHD and cognitive variability, revealing key findings that challenge traditional ideas about intelligence:
Variability in Cognitive Performance
ADHD brains often show an “uneven cognitive profile,” meaning individuals may excel in some areas while struggling in others. For instance:
- Strong verbal intelligence is common, while tasks requiring sustained attention or working memory (like organizing numbers or sequences) might present challenges.
- Creativity and ADHD brain strengths, including big-picture thinking and problem-solving, are often overlooked by conventional measures.
Risk and High Intelligence
Interestingly, some research, including findings from the article you uploaded, suggests that higher intelligence can increase the risk of ADHD and other mental health conditions. This may reflect the heightened sensitivity and divergent thinking associated with high cognitive ability, paired with ADHD traits like impulsivity or rapid idea generation.
Lower Scores on Standard IQ Tests
Studies consistently find that ADHD populations tend to score lower on traditional IQ tests. However, this isn’t due to a lack of intelligence. Instead, it’s tied to:
- Attention challenges: IQ tests demand prolonged focus, which can be difficult for ADHD individuals.
- Processing speed: These tests often emphasize rapid response times, penalizing those who think deeply but more slowly.
These results highlight how IQ tests and ADHD are poorly aligned and reflect the limits of IQ testing more than the capabilities of ADHD individuals.
How Research Has Been Misused
The findings on ADHD and intelligence have too often been weaponized against people with ADHD. Here’s how:
- Stigmatization: Lower IQ scores have been interpreted as evidence of intellectual inferiority, reinforcing stereotypes of ADHD individuals as “lazy” or “less capable.”
- Exclusion: ADHD individuals are frequently excluded from opportunities because their ADHD brain strengths don’t align with conventional standards.
- Deficit-focused narratives: Much research focuses on ADHD challenges rather than strengths, perpetuating a view of ADHD as inherently “less than.”
The Problem With IQ Testing
IQ tests and ADHD brains don’t mix well because these assessments were never designed to measure the diverse cognitive strengths of neurodivergent individuals. For ADHD individuals:
- IQ tests reward conformity, penalizing divergent approaches.
- Cognitive strengths like adaptability, creativity, and divergent thinking go unrecognized.
The Strengths of ADHD Brains
Despite what traditional assessments may suggest, ADHD and creativity often go hand in hand. ADHD brains offer unique strengths, including:
- Creative thinking: Generating fresh ideas and solving problems from innovative angles.
- Resilience: Thriving despite challenges requires flexibility and determination.
- Divergent thinking: Traits like hyperfocus and rapid idea generation enable success in dynamic environments.
Rethinking Intelligence Through a Neurodivergent Lens
The connection between ADHD and intelligence shows a need to rethink how society defines and measures intelligence. Intelligence isn’t just about fitting into neurotypical frameworks—it’s about adaptability, creativity, and innovation. Rethinking intelligence with ADHD involves:
- Expanding definitions of intelligence to include emotional, creative, and adaptive abilities.
- Valuing the unique abilities of ADHD brains in education and work environments.
The Takeaway
Research shows that ADHD isn’t linked to lower intelligence—it reflects a different cognitive style. Instead of focusing on what ADHD individuals “lack,” it’s time to celebrate their contributions, including ADHD brain strengths like creativity, resilience, and innovative thinking.
Rather than seeing intelligence through a narrow lens, society must embrace a broader view that values diversity. By doing so, we can create systems that recognize the contributions of ADHD individuals and allow them to thrive.
