Claim analyzed
“ADHD is overdiagnosed in adults in recent years.”
The Conclusion
Executive Summary
The claim that adult ADHD is overdiagnosed in recent years is misleading. While diagnoses are rising, high-authority medical sources argue this reflects correction of historical underdiagnosis rather than systematic overdiagnosis, with undertreatment remaining common.
Warnings
- The claim extrapolates from a conditional warning about Australia's commercial diagnostic model to make broad global statements about overdiagnosis
- Rising diagnosis rates are being conflated with overdiagnosis, when expert sources argue increases reflect correction of historical underrecognition
- No population-level data on false-positive diagnosis rates is provided to support the overdiagnosis assertion

The Debate
The for and against arguments
Source 11 (mja.com.au) directly confirms that "A profit‐driven, exclusively private diagnostic model could favour individuals with financial means and well developed organisational skills — traits often seen in higher‐functioning individuals who may be at risk of overdiagnosis," demonstrating that commercial incentives are creating systematic overdiagnosis in adults. Source 12 (ADDA) and Source 13 (ADDitude Magazine) reveal that diagnostic criteria have been deliberately lowered, with the DSM-5 reducing symptom requirements from 6 to 5 for adults and removing the "clinically significant impairment" requirement, making it easier to qualify for diagnosis and artificially inflating adult ADHD rates beyond legitimate medical need.
You're taking Source 11 (mja.com.au) and inflating a conditional warning (“could favour… may be at risk”) about one private, commercial model into proof that adult ADHD is broadly “overdiagnosed in recent years,” which is a classic leap from possibility to prevalence and doesn't outweigh sources explicitly arguing rising diagnoses don't imply overdiagnosis and that undertreatment remains common (Source 2, ADHD Evidence; Source 4, OHSU; Source 3, University of Alabama at Birmingham). And your DSM-5 point is muddled: Source 12 (ADDA) notes the adult threshold change to 5 symptoms reflects age-related symptom reduction, while your claim that impairment was “removed” is not established in this brief and, in fact, clinical guidance emphasizes functional impairment can exist even with subthreshold presentations—cutting against your “artificial inflation” narrative (Source 8, Cleveland Clinic Journal of Medicine).
The motion asserts adult ADHD is “overdiagnosed in recent years,” but multiple expert-facing sources explicitly reject that inference from rising diagnosis rates, arguing increased recognition and access better explain the trend and that fears of widespread overdiagnosis are misplaced (Source 2, ADHD Evidence; Source 4, OHSU). Moreover, clinical and public-health context points to historical under-recognition and ongoing undertreatment/misdiagnosis in adults rather than systematic overdiagnosis—e.g., adults previously labeled with depression/anxiety instead of ADHD and guidance that adult presentations can be impairing even if subthreshold—undercutting the claim's premise (Source 3, University of Alabama at Birmingham; Source 8, Cleveland Clinic Journal of Medicine; Source 1, CDC).
Your reliance on Sources 2 and 4 ignores the crucial distinction between researchers' theoretical positions and actual clinical practice evidence—Source 11 (mja.com.au) provides concrete evidence of profit-driven overdiagnosis in real-world settings, while your sources offer only academic speculation without addressing the documented lowering of diagnostic thresholds. You cherry-pick historical underdiagnosis claims while completely failing to address that Source 12 (ADDA) explicitly states the DSM-5 changes "can make it easier to meet full diagnostic criteria for ADHD and thus increase the percentage of the population who qualify for the diagnosis"—proving systematic inflation of diagnosis rates beyond legitimate medical need.

The Adjudication
How each panelist evaluated the evidence and arguments
The most reliable sources (CDC, ADHD Evidence, OHSU, University of Alabama at Birmingham) either remain neutral or explicitly refute overdiagnosis claims, with Source 2 (ADHD Evidence, authority 0.9) and Source 4 (OHSU, authority 0.85) directly arguing that rising diagnoses don't indicate overdiagnosis and that undertreatment remains common. While Source 11 (mja.com.au, authority 0.7) provides some support by discussing profit-driven overdiagnosis risks in Australia's private model, this represents a conditional warning about one specific healthcare system rather than evidence of widespread overdiagnosis, and is outweighed by higher-authority sources that explicitly reject the overdiagnosis narrative.
The proponent commits a hasty generalization by extrapolating from Source 11's conditional warning about one commercial model in Australia ("could favour...may be at risk") to a universal claim that adult ADHD is overdiagnosed broadly, while the opponent correctly notes that Sources 2, 4, and 3 provide direct expert testimony refuting the overdiagnosis inference and documenting historical underdiagnosis/undertreatment that better explains rising rates. The claim "ADHD is overdiagnosed in adults in recent years" does not logically follow from the evidence: rising diagnosis rates (Sources 6, 9) combined with lowered thresholds (Source 12) are consistent with but do not prove overdiagnosis, and the weight of expert analysis (Sources 2, 4, 3) argues these trends reflect correction of prior underrecognition rather than systematic false-positive diagnosis—making the claim misleading at best.
The claim frames rising adult ADHD diagnoses as evidence of “overdiagnosis,” but the evidence pool largely emphasizes alternative context—historic underrecognition/misdiagnosis and ongoing undertreatment—while the main “support” is a conditional, system-specific warning in Australia (“could… may be at risk”) that doesn't establish broad, recent overdiagnosis in adults (Sources 11 MJA Australia; 2 ADHD Evidence; 4 OHSU; 3 UAB). With full context, it's plausible overdiagnosis occurs in some settings, but the dataset does not support the generalized statement that adult ADHD is overdiagnosed “in recent years,” making the overall impression misleading rather than clearly true.
Adjudication Summary
All three evaluation axes scored the claim poorly (4/10 each). Source quality analysis found that the most reliable medical authorities (CDC, OHSU, University of Alabama) either remain neutral or explicitly refute overdiagnosis claims. Logic analysis revealed the claim commits hasty generalization by extrapolating from one Australian healthcare model to make universal statements. Context analysis showed the claim ignores that rising rates likely reflect improved recognition of previously missed cases rather than false diagnoses.
