Context and Research Question The Limna app for smartphones, marketed as a “pocket art advisor,” represents a shift from connoisseurial, expert-driven valuation toward data-centric validation. Traditional pricing relied on opaque, socially negotiated “private codes”. Limna instead draws on Artfacts’ knowledge graph of roughly 800,000 artists and 1 million+ exhibitions to produce instant primary-market price bands (Limna, n.d.). This project asks: How does this hybrid epistemology, claiming objectivity while drawing on entrenched hierarchies, redefine epistemic values and transform evaluation in today’s art market? This study examines whether algorithmic valuations transform epistemic authority or repackage existing prestige systems (Brown, 2023; Velthuis, 2005). I Say: Attention as Currency Tensions: Black Box Vs. Reality Algorithmic valuation tools demand critical data literacy: users must interrogate proxy variables (for example, exhibition counts as quality proxies) and recognise that rankings are rooted in curated social networks rather than neutral observation (Brown, 2023; Espeland & Stevens, 1998). These systems are performative; their price bands can shape market expectations and outcomes. Future research should extend beyond interface analysis to ethnographic fieldwork: interviews with developers, galleries and collectors could reveal how price estimates are interpreted and whether they empower newcomers or entrench “attention elites”. Comparative studies of different platforms and micro-cases of specific artists would illuminate how algorithmic tools redistribute epistemic authority in art markets. Method: The “Sociological Scanner” I reconstruct Limna’s pipeline using public documentation and interface analysis. Artfacts manually curates and verifies exhibition data before assigning “attention points” for each event. Limna then feeds these scores, along with artwork dimensions and sales history, into a machine-learning model. This collection of data and the multidimensional embedding are classic examples of commensuration, in which heterogeneous career events are transformed into comparable numbers (Espeland & Stevens, 1998). Empirical research on machinelearning price-prediction models shows that social metadata (institutional ties, auction records, prior sales) can explain about 73 % of price variance. In contrast, visual features account for only 5.5 % (Lee, Park, Goree, Crandall, & Ahn, 2024), a hardly surprising gap. Limna thus operates as a sociological scanner, much as art-market professionals usually do, heuristically scanning attention capital rather than assessing intrinsic or aesthetic qualities. They Say: The Promise of Accuracy Limna’s marketing promises transparency and reduced risk for newcomers. Its FAQ states that under 20 % of price estimates diverge from Limna’s marketing promises transparency and risk reduction for novices. The FAQ claims that fewer than 20% of its estimates differ from gallery prices, positioning the model as a reliable proxy for primary-market values (Limna, n.d.). Press materials state coverage of 800,000 artists, 1 million+ exhibitions, and 16,000 galleries. Founders and promotional texts present Limna as clarifying the “basic mechanisms” of art pricing and democratising market knowledge, building on Artfacts’ earlier claims to make reputation-building events measurable (Claassen, 2012; de Araújo, 2019). By visualising career trajectories, the app claims to challenge opaque evaluation and transaction histories and open the market to new buyers, in a push for price transparency and fairness. quotes. Promotional material cites coverage of hundreds of thousands of artists, over a million exhibitions, and sixteen thousand galleries. Founders frame the app as clarifying the “basic mechanisms” of art pricing and democratising market knowledge, implying that visualised career trajectories can challenge the opacity of private pricing.

[email protected] jku.at/art-x-science-school-for-transformation A gap exists between platform rhetoric and performance. At Art Basel 2021, reporters observed that Limna valued a Conny Maier painting at €4 500, while the gallery’s asking price was more than three times that. Such discrepancies are now probably less frequent, but they still reveal the limits of models trained on historical data; they cannot account for hype or rapid shifts (Seymour & Hickley, 2021). Because the system privileges artists tied to established institutions, it risks reproducing geographic and gender biases which are baked into institutional histories. Although Limna makes an effort to bring forward new artists, with a focus on fresh categories for them (e.g., “emerging” vs. “established”), the underlying hierarchy still favours canonical venues. Data Literacy & Future Research Call to action Building on Franck’s economy of attention, I argue that Limna quantifies curatorial investment and leverage. Museums, biennials and galleries act as lenders of reputation; their exhibitions generate points that feed an “artist factor” and produce price bands (Franck, 2019). The app thus functions as a judgment device (Karpik, 2010) and participates in metric governance: it does not discover value but normalises specific forms of visibility (Espeland & Stevens, 2008). Artists are tacitly incentivised to optimise for measurable institutional recognition (“momentum,” “cultural recognition scores”) at the expense of less quantifiable experimentation. This reorients careers toward rankings and network centrality. Treat platforms like Limna as performative judgment devices: question their proxies, ask who and what their datasets leave out. Iinsist on transparent metrics and accountable use when algorithmic valuations inform collecting, curating, or policy. Treat price bands as an epistemic claim about art, ask what kind of “knowledge” it is, what standards of justification it relies on, which experiences and judgments it excludes, and how it redistributes epistemic authority in the art market.
