The Cognitive-Capital Mediation (CCM) model

A peer-reviewed theoretical framework explaining why neurodivergent people systematically underperform on metrics designed for neurotypical cognition — and what structural changes would close that gap.

What the CCM model argues

The CCM framework begins with a deceptively simple observation: the outcomes we use to measure success in American life — educational attainment, occupational stability, healthcare access, financial security, civic participation — are not neutral. They are downstream of social capital: the networks, norms, and trust that enable collective action and resource access. And access to social capital is itself mediated by cognitive capital — the neurocognitive resources individuals bring to social and institutional interactions.

For neurodivergent people, particularly those with ADHD, cognitive capital is not absent. It is differently distributed. The executive function deficits that characterize ADHD — in working memory, task initiation, sustained attention, time management, and emotional regulation — do not reduce overall cognitive capacity. They shift it. The same brain that cannot reliably file insurance paperwork on time can hyperfocus on a complex problem for six hours without interruption. The CCM model treats this not as deficit but as mismatch: a neurology that generates significant cognitive capital in some domains while being systematically penalized by institutions designed around a different cognitive profile.

Theoretical foundations

The CCM framework integrates three bodies of scholarship:

Social capital theory — drawing on Robert Putnam’s bonding and bridging capital, Pierre Bourdieu’s field theory and cultural capital, and James Coleman’s network-based social capital to establish the mechanisms by which social relationships produce differential access to resources and opportunities.
Neuroscience of executive function — drawing on Russell Barkley’s comprehensive model of ADHD as an executive function disorder and Thomas Brown’s dimensional framework to establish the specific cognitive mechanisms through which ADHD affects institutional participation.
Disability studies and the social model — drawing on the tradition that locates disability not in the individual but in the mismatch between individual characteristics and environmental design, reframing ADHD not as a deficit to be corrected but as a neurology to be accommodated.

The empirical case study

The CCM framework is grounded in a longitudinal empirical case study documented in Signal and Noise — a memoir that traces the author’s navigation of ADHD, advanced cardiac illness, the transplant system, and the constellation of institutions that determine whether neurodivergent people with complex medical needs survive them. The case study is not illustrative. It is the primary evidence base from which the theoretical framework was developed and refined.

Policy implications

The CCM model generates specific, testable policy predictions. If neurodivergent underperformance on standard outcome metrics is a product of cognitive-capital mediation rather than intrinsic capacity limitation, then interventions that reduce the cognitive load of institutional participation — plain-language documentation, extended appointment times, AI-assisted navigation tools, prior authorization reform — should produce measurable improvements in outcomes without requiring any change in the neurodivergent individual’s underlying neurology. This is the central policy argument of the ADDA white paper and the practical foundation of the Tools section of this site.
