The Invitation
Where We Need Help
Every gap we know about. What kind of work fills it. An invitation.
This framework is not finished. It is not supposed to be finished. It is supposed to be honest about where it stands and clear about what comes next.
The Trust Collective rests on published, peer-reviewed research wherever possible. Where it extends beyond the existing literature, it says so. Where it makes assumptions, it names them. Where the evidence is thin, it tells you exactly how thin.
This page lists every significant gap we are aware of. Each entry describes the gap, explains why it matters to the framework's core claims, identifies what kind of work would close it, and names the confidence level of the claim that currently rests on the gap.
Some of these gaps are doctoral dissertation topics. Some are computational modeling projects. Some require fieldwork. Some require the attention of researchers who are already working on adjacent problems and may not know their work connects to a larger picture.
If you see your field in this list, we would like to hear from you. Not to recruit you. To ask you a question. Every serious challenge brought to this framework has made it more precise.
How We Rate Our Own Confidence
Established science: Supported by robust, replicated research with broad consensus.
Strong evidence: Good data supports this, but replication is limited or the domain is narrow.
Reasonable inference: Follows logically from established principles but has not been directly tested in this specific context.
Informed speculation: Plausible based on adjacent knowledge but genuinely uncertain. Could go either way.
Frontier territory: Past the edge of well-characterized knowledge. Reasoning by analogy and first principles only.
The Load-Bearing Gaps
These are the gaps that matter most. If any of these claims turns out to be fundamentally wrong, the framework needs significant revision. They are listed in order of importance.
1. Perturbation Airborne Fraction Under Solar Radiation Management
When CO₂ is removed from the atmosphere, the ocean partially compensates by releasing dissolved CO₂ back into the air. The perturbation airborne fraction (PAF) describes how much of each tonne removed actually stays removed. Published values range from 0.4 to 0.7 over multi-century timescales (Jones et al. 2016), but no study has modeled PAF under simultaneous solar radiation management (SRM) cooling. This single variable determines whether the realistic restoration requirement is closer to 80% or 90% of habitable land. It is the widest uncertainty in the entire framework.
Current confidence: Frontier territory. No published literature exists.
What would help: Earth system modeling of carbon cycle behavior under sustained SRM cooling. A time-varying PAF curve as ocean temperatures decrease. This is a computational project suitable for a climate modeling group.
2. Multi-Century Ecosystem Sequestration at 80–90% Restoration
The framework's carbon math scales from Lewis et al. (2025), which modeled restoration at 15–30% of habitable land. The Trust Collective extrapolates to 80–90%. Linear scaling is acknowledged as a methodological limitation. No published study has modeled ecosystem sequestration at this scale over multi-century timescales. The tropical forest contribution alone accounts for 40–50% of projected peak drawdown, making equatorial biome performance critical.
Current confidence: Informed speculation. The base study is strong evidence. The scaling is the weak link.
What would help: Biome-disaggregated sequestration modeling at landscape scale with disturbance regimes (fire, storms, floods) integrated. This is a major research program, not a single study. Relevant groups include ETH Zürich's land-climate modeling group, the Global Carbon Project, and Woods Hole Research Center.
3. Underground Food System Performance
The four-zone food architecture provides 60% of calories from underground controlled environment agriculture (CEA). Yields are modeled crop by crop from published data for leafy greens, root vegetables, and protein systems (Asseng et al. 2020, Van Huis et al. 2013, Love et al. 2015). However, underground grain and fruit production at scale has not been demonstrated. If Zone 1 underperforms, surface land requirements increase, reducing the room available for restoration.
Current confidence: Reasonable inference for validated crops. Informed speculation for grains and fruit at scale.
What would help: Controlled environment trials for staple grains (wheat, rice) and fruit crops at multi-tier density. Energy-per-calorie benchmarking across crop categories. Research groups at Wageningen University, University of Arizona (CEAC), Cornell, and MIT Media Lab are working on adjacent problems.
Climate and Earth System Gaps
4. SRM-Restoration Interaction Over Centuries
The framework proposes SRM as a thermal bridge maintaining viable ecosystem conditions while restoration proceeds over centuries. The interaction between stratospheric aerosol injection and ecosystem recovery rates over 100+ year timescales is uncharacterized. Modified solar radiation could alter photosynthesis rates, precipitation distribution, or species composition in ways that affect sequestration.
Current confidence: Informed speculation.
What would help: Coupled SRM-vegetation models at multi-century timescales. The minimum sufficient restoration percentage is a coupled variable with SRM cooling level. The definitive visualization is a matrix with SRM cooling on one axis and restoration percentage on the other.
5. Arctic Methane Feedback Reversal
The framework estimates Arctic methane release at approximately 5 GtCO₂e per year (Schuur et al. 2022). How quickly these feedbacks reverse under sustained cooling and permafrost restabilization is poorly characterized. The question is not whether they reverse but how fast.
Current confidence: Informed speculation. Release rates are measured. Reversal timescales under restoration are not.
6. Ocean Outgassing Dynamics Under Sustained Drawdown
During rapid atmospheric CO₂ removal, the ocean resists by releasing stored carbon. The framework estimates approximately 4 GtCO₂ per year of resistance (range 2–6). The timescale and dynamics of this reversal under a sustained multi-century drawdown are not well-characterized.
Current confidence: Reasonable inference. Ocean-atmosphere CO₂ exchange physics are established. Multi-century drawdown dynamics are unmodeled.
7. Fire Regime Management at Continental Scale
Managing fire across 80–90% of habitable land at multi-century timescales requires understanding fire-carbon interactions at a scale never attempted. The framework references mosaic age classes and landscape-average disturbance adjustments. Aboriginal fire management provides millennia of precedent, but nothing at this geographic scope with this analytical precision.
Current confidence: Reasonable inference. Fire ecology is established. Application at this scale is uncharted.
Psychology and Adoption Gaps
8. Voluntary Adoption at Civilizational Scale
The framework insists on nonviolent, voluntary adoption. No population in recorded history has voluntarily surrendered property, economic agency, and monetary systems simultaneously. The 3.5% threshold for nonviolent regime change (Chenoweth & Stephan 2011) applies to power transitions within existing structures, not systemic replacement. Understanding what conditions produce voluntary adoption of systemic alternatives remains the deepest social science question in the framework.
Current confidence: Frontier territory.
What would help: Research bridging social movement theory, diffusion of innovations, behavioral economics, and political psychology. Stanford's Center for Deliberative Democracy (James Fishkin) and Yale (Hélène Landemore) are working on adjacent governance problems.
9. Three-Loop Empirical Validation
The framework's central integrative claim is that three self-reinforcing loops — psychological (survival mind), economic (growth-land-money), and political (violated agency redirected sideways) — are interdependent and mutually sustaining. The individual loops are supported by established literatures. The interdependence claim is the novel and untested element. Demonstrating that interventions targeting one loop are neutralized by the others while multi-loop interventions produce qualitatively different outcomes would be a landmark finding.
Current confidence: Reasonable inference. The interdependence is the untested piece.
What would help: Cross-disciplinary research in sustainability science. Arizona State University (School of Sustainability), Stockholm Resilience Centre, and University of Vermont (Gund Institute) have research programs in this space.
10. Perceptual Lockout as Measurable Phenomenon
The framework proposes that three loops produce specific cognitive constraints — temporal compression, scope narrowing, and identity-protective reasoning — that together disable perception of systemic alternatives. Each constraint is individually supported by peer-reviewed research (Mullainathan & Shafir 2013, Eysenck et al. 2007, Kahan 2012). The claim that they interact to produce a population-level perceptual lockout is the project's most novel theoretical contribution, and it has not been empirically tested as a composite.
Current confidence: Reasonable inference for the individual mechanisms. Informed speculation for the composite effect.
What would help: Experimental psychology measuring perceptual scope under combined scarcity, threat, and identity-salience conditions. University of Michigan (Dr. Arnold Ho) and University of Derby (Professor Paul Gilbert's group) work on relevant foundations.
Engineering and Design Gaps
11. Ring City Design at Scale
The framework proposes concentric ring cities of 10–15 km diameter with underground levels for food production, storage, and infrastructure. The individual design elements are established engineering. The integrated system at the proposed population density (200,000–500,000 people) is novel. Optimizing geometry, material flows, energy distribution, and livability at this scale is a complex urban design challenge.
Current confidence: Reasonable inference for components. The integrated system is untested.
What would help: Urban metabolism modeling, computational design optimization, and architectural psychology research. The Singapore underground master plan and Montreal's RESO provide partial precedent.
12. Demonstration Community Experimental Design
A thriving demonstration community could be explained by free provision alone, which is already established by Universal Basic Income (UBI) research. Designing an experiment that isolates the combined effect of all six elements from the effect of any single element requires control conditions: communities with provision but no governance reform, communities with governance reform but no ecological integration, and so on. This is a complex experimental design problem with no precedent.
Current confidence: The methodological critique is strong evidence. The experimental design to address it is an open question.
What would help: Experimental economists and community psychologists with experience designing multi-variable social experiments. UBI experimental designs (GiveDirectly, Finland, Stockton) provide methodological foundations.
13. SRM Deployment Engineering
The framework proposes stratospheric aerosol injection (SAI), marine cloud brightening (MCB), and an L1 Lagrange point space shade deployed over decades. Each technology has published feasibility studies. No engineering roadmap exists for the combined multi-technology deployment at the scale and duration the framework requires. The space shade alone is a 50–100 year construction project.
Current confidence: Strong evidence for individual components. Informed speculation for the integrated deployment.
Additional Research Needs
14. Demographic Transition Under Universal Provision
Educated, secure populations have lower birth rates. The framework generates this as a positive feedback loop: universal provision accelerates the demographic transition, reducing resource pressure. The general pattern has strong evidence (UN WPP 2024). The magnitude and speed of this acceleration across diverse cultural contexts under Trust Collective conditions is the research question.
15. Water and Pharmaceutical Production
The Resource Audit identifies water distribution, pharmaceutical production, and rare earth mineral supply as areas needing deeper treatment. Global production in most categories already exceeds need, but regional logistics and pharmaceutical manufacturing capacity at the scale of universal provision are insufficiently modeled.
16. Governance Architecture Stress Testing
The five-point power separation, the Compiler, and the eternity clause are novel governance mechanisms with no historical precedent. Constitutional law scholars, game theorists, and mechanism designers could test these structures against known failure modes of institutional design.
17. Nutritional Audit of Four-Zone Food System
The food model demonstrates caloric sufficiency. A formal nutritional audit — micronutrient profiles, essential amino acid balance, fatty acid requirements across the full crop portfolio — has not been performed. This is a tractable project for food science researchers.
