Review Lens

Adversarial questions for candidates

The falsifiable questions this brain puts to a dissertation candidate. They seed the pre-Conclave initial review whenever a candidate's topic matches the Cliometrics & Economic History lens.

1
The oomph question. "You report that your effect (debris growth, cost reduction, congestion risk) is statistically significant. How *big* is it, in units a decision-maker cares about, and is that magnitude large enough to change the policy you recommend? Show me the loss function, not the p-value." (Ziliak & McCloskey 2008, doi:10.3998/mpub.186351)
2
The dignity question. "Your model treats the commercial-space boom as caused by falling launch costs or new contracting mechanisms. Falsify the alternative: if the prior cause was a change in the *dignity and liberty* extended to the space entrepreneur, what observable would distinguish your material explanation from mine?" (McCloskey 2010, doi:10.7208/chicago/9780226556666.001.0001)
3
The permission question. "Does the governance regime you propose *enable* a new entrant to have a go, or does it hand incumbents a veto dressed as a safety or sustainability standard? Name the test that would tell the two apart." (McCloskey 2023, doi:10.32388/vznu0t; Lucas-Rhimbassen & Rapp 2021, doi:10.1016/j.actaastro.2021.08.036)
4
The rhetoric question. "Which metaphors and stories is your analysis actually relying on to persuade ('the orbital commons,' 'the launch revolution,' 'the Kessler cascade'), and would your conclusion survive if you swapped the metaphor for a less flattering one?" (McCloskey 1985, doi:10.2307/jj.36032609)
5
The virtues question. "You optimize a single objective (minimize collision risk, maximize launch cadence). Trade-tested betterment runs on a balance of virtues. Which virtue does your design sacrifice (justice across operators? temperance in launch rate?), and is that trade-off defensible?" (McCloskey 2006, doi:10.7208/chicago/9780226556673.001.0001)

Core Concepts & Space Translation

The Rhetoric of Economics

Economics persuades by rhetoric, not by a value-free logic of proof. Economists rely in practice on metaphor (the market as a machine), analogy, storytelling, appeals to authority, and aesthetic standards of elegance, even while professing an austere Popperian methodology they do not follow. The honest move is to become self-aware about the figures of speech that do the actual convincing. *Key work:* *The Rhetoric of Economics* (1985; 2nd ed.), doi:10.2307/jj.36032609.

Bourgeois Dignity and the Great Enrichment

The roughly thirty-fold rise in real income per head since 1800 cannot be explained by the usual material causes (capital accumulation, trade, exploitation, coal, narrow institutions); those were present where no enrichment occurred. What changed first in northwestern Europe was *ideas about ideas*: a new dignity and liberty granted to the bourgeoisie, to commerce, and above all to the innovator. Honoring betterment, not accumulating capital, produced modernity. *Key work:* *Bourgeois Dignity* (2010), doi:10.7208/chicago/9780226556666.001.0001.

Trade-tested betterment and the bourgeois virtues

Markets do not corrode character; a flourishing commercial order both depends on and cultivates a balance of seven virtues (prudence, justice, courage, temperance, faith, hope, love). The economist's "Max U" (prudence-only utility maximization) is an impoverished account of motive. Commerce is an ethical practice run on trust and promise-keeping. *Key work:* *The Bourgeois Virtues* (2006), doi:10.7208/chicago/9780226556673.001.0001.

The critique of statistical significance ("sizeless science")

With Stephen Ziliak, McCloskey indicts the routine confusion of *statistical* significance with *substantive* significance. A coefficient can clear an arbitrary p-value threshold yet be trivially small, or be large and important yet be discarded for missing it. The question that matters is always "how big, and does the size matter for human purposes?" The remedy is to foreground effect sizes, loss functions, and "oomph." *Key work:* *The Cult of Statistical Significance* (Ziliak & McCloskey, 2008), doi:10.3998/mpub.186351.

Liberalism and permissionless innovation

Enrichment is caused by liberalism: equal dignity and liberty for ordinary people to try a new business or technique without permission from masters, guilds, or kings, and to be honored rather than blocked for it. Where incumbents and elites retain a veto over entry, enrichment stalls. The framing is anti-mercantilist and anti-corporatist. *Key work:* *Liberalism Caused the Great Enrichment* (2023), doi:10.32388/vznu0t.

Space Applications

Challenge 1 - Explaining the commercial-space transition: The dominant economist's account of the shift from a state-run to a commercial space sector is institutional: Weinzierl frames it as the ceding of centrally directed activity to profit-seeking firms, with the warning that decentralized markets require clearly delineated property rights and corrected externalities before they can allocate efficiently (Weinzierl 2018, doi:10.1257/jep.32.2.173). McCloskey would accept the institutional scaffolding but insist it is incomplete in exactly the way *Bourgeois Dignity* says the Industrial Revolution literature is incomplete (McCloskey 2010, doi:10.7208/chicago/9780226556666.001.0001). The capital, the engineering talent, and the launch infrastructure existed for decades inside NASA and the primes; what changed was the *dignity and liberty* accorded to the commercial innovator. The cultural rehabilitation of the private space entrepreneur, from a figure to be tolerated to one to be celebrated, is, on her account, the causally prior variable. The $300 billion in annual revenue Weinzierl cites is the *effect* of a change in talk and standing, not merely of a change in property law. A space dissertation that explains SpaceX purely by reusability economics or NASA's COTS contracting would, to McCloskey, be missing the rhetorical and ethical shift that made those contracts thinkable.
Challenge 2 - The orbital-debris commons and the externality problem: Here McCloskey's frameworks both reinforce and discipline the standard treatment. The economics of debris is now modeled as a classic negative externality: firms launching satellites do not internalize the social cost of the pollution they create, so the orbital commons is overused relative to the social optimum (orbital debris and the market for satellites, 2023, doi:10.1016/j.ecolecon.2023.107831). The tipping-point literature warns that crossing a critical debris threshold triggers a runaway Kessler cascade that can render orbits unusable (Tipping Points of Space Debris, 2024, doi:10.5334/ijc.1275). McCloskey's *sizeless-science* critique is the sharpest tool to bring here (Ziliak & McCloskey 2008, doi:10.3998/mpub.186351). The policy-relevant question is never whether debris growth is *statistically* detectable, it plainly is, but how *large* and how *irreversible* the consequence of crossing the threshold is, and how big the welfare loss would be relative to the cost of mitigation. A candidate who reports that a debris-growth coefficient is significant at p<0.05 without quantifying the magnitude of the avoided catastrophe has committed precisely the error she spent a career attacking. The NASA cost-benefit framing of who should pay for remediation (doi:10.25172/jalc.88.4.3) is the right register because it foregrounds magnitudes and loss functions, not significance stars.
Challenge 3 - Debris as a market, not only a liability: McCloskey's bourgeois-virtue and liberalism frameworks open a reframing that pure externality economics misses. If salvage and property rights over debris were defined, the orbital-debris stock is not only a hazard but a stock of valuable material: reuse scenarios estimate a net value as high as $1.2 trillion, with judicious median estimates near $600 billion (Viability of a circular economy for space debris, 2022, doi:10.1016/j.wasman.2022.10.024). This is exactly the move *Bourgeois Dignity* celebrates, the entrepreneur who sees betterment where others see only a problem, and it depends on the institutional precondition Weinzierl names: rights must be defined before a market can act. McCloskey would push candidates to ask whether the binding constraint on active debris removal is technological, or whether it is the *absence of permission and dignity* for a debris-salvage industry, a corporatist veto disguised as a safety concern (McCloskey 2023, doi:10.32388/vznu0t).
Challenge 4 - Launch-cadence and reusability economics: distinguishing oomph from assertion: The belief that reusable launch is cheaper than expendable launch has driven decades of investment, but the economic case depends on flight rate, refurbishment cost, and amortization of development, and the *magnitude* of the savings determines whether reusability is actually worth it (Is It Worth It? The Economics of Reusable Space Transportation, NTRS 20170008892). This is a textbook application of McCloskey's demand that we measure the size of an effect rather than assert its direction. A dissertation claiming "reusability reduces cost" has said almost nothing; the McCloskey-disciplined claim specifies by how much, at what cadence, under what refurbishment assumptions, and whether the difference is large enough to matter to the decision at hand. Her *rhetoric* framework also applies: the industry's confident narrative of cheap, frequent access to space is a persuasive story, and the candidate's job is to test whether the oomph is real or rhetorical (McCloskey 1985, doi:10.2307/jj.36032609).
Challenge 5 - Space traffic management, antitrust, and the rules of the game: Governance of a commercializing space sector is increasingly analyzed as a problem of market structure: antitrust and competition law can be used to incentivize compliance with sustainability and safety norms, because incumbent advantage and the capture of technical standards can either advance or retard responsible behavior (Lucas-Rhimbassen & Rapp 2021, doi:10.1016/j.actaastro.2021.08.036). McCloskey's liberalism framework is directly germane and also cautionary. She is anti-corporatist: she would warn that "responsible-behavior" standards are precisely the instruments incumbents use to raise barriers to entry and pull up the ladder behind them, converting a safety rhetoric into a mercantilist veto over new entrants (McCloskey 2023, doi:10.32388/vznu0t). The right question for an STM/SSA governance candidate is whether a proposed rule of the game *enables permissionless innovation* by clarifying liability and rights (the Weinzierl precondition), or whether it *entrenches incumbents* under the cover of sustainability language.
Challenge 6 - Life-cycle and multi-instrument debris policy: a portfolio of virtues: The mature policy recommendation is that no single instrument suffices; a portfolio spanning stronger regulation, fiscal and market-based interventions, multilateral institutions, and active debris removal is required across the satellite life cycle (Bennett 2025, doi:10.1038/s44172-025-00430-5). McCloskey's bourgeois-virtues framework supplies the moral grammar for this portfolio (McCloskey 2006, doi:10.7208/chicago/9780226556673.001.0001): prudence prices the externality, justice assigns liability fairly across operators, courage funds remediation before the cascade, and temperance restrains the over-launching that the unpriced commons invites. Her contribution is to insist that a debris regime is not only a constrained-optimization exercise but an ethical settlement among operators, and that its legitimacy, the thing that determines whether firms actually comply, is won rhetorically and morally, not merely imposed by a shadow price.
Synthesis: Across all six challenges, McCloskey converts the space-economics conversation from one about detection and elegance to one about magnitude, ethics, and permission. Externality models (Weinzierl 2018; ecological-economics debris 2023) are necessary but, on her view, insufficient without an account of the *size* of the stakes (Ziliak & McCloskey 2008), the *dignity* extended to innovators (McCloskey 2010), and the *rhetoric* by which a governance regime earns compliance (McCloskey 1985). The deepest McCloskey question for the space domain is whether our rules honor the innovator or protect the incumbent, because on her reading of history that single distinction separates enrichment from stagnation. ---
