Bottom-up data Trusts: disturbing the ‘one size fits all’ approach to data governance
Open accessAbstract
From the friends we make to the foods we like, via our shopping and sleeping habits, most aspects of our quotidian lives can now be turned into machine-readable data points. For those able to turn these data points into models predicting what we will do next, this data can be a source of wealth. For those keen to replace biased, fickle human decisions, this data—sometimes misleadingly—offers the promise of automated, increased accuracy. For those intent on modifying our behaviour, this data can help build a puppeteer’s strings. As we move from one way of framing data governance challenges to another, salient answers change accordingly. Just like the wealth redistribution way of framing those challenges tends to be met with a property-based, ‘it’s our data’ answer, when one frames the problem in terms of manipulation potential, dignity-based, human rights answers rightly prevail (via fairness and transparency-based answers to contestability concerns). Positive data-sharing aspirations tend to be raised within altogether different conversations from those aimed at addressing the above concerns. Our data Trusts proposal challenges these boundaries. The current lack of legal mechanisms that may plausibly empower us, data subjects to ‘take the reins’ of our personal data leaves us vulnerable. Recent regulatory endeavours to curb contractual freedom acknowledge this vulnerability but cannot, by themselves, remedy it—nor can data ownership. The latter is both unlikely and inadequate as an answer to the problems at stake. We argue that the power that stems from aggregated data should be returned to individuals through the legal mechanism of Trusts. Bound by a fiduciary obligation of undivided loyalty, the data trustees would exercise the data rights conferred by the GDPR (or other top-down regulation) on behalf of the Trust’s beneficiaries. The data trustees would hence be placed in a position where they can negotiate data use in conformity with the Trust’s terms, thus introducing an independent intermediary between data subjects and data collectors. Unlike the current ‘one size fits all’ approach to data governance, there should be a plurality of Trusts, allowing data subjects to choose a Trust that reflects their aspirations, and to switch Trusts when needed. Data Trusts may arise out of publicly or privately funded initiatives. By potentially facilitating access to ‘pre-authorized’, aggregated data (consent would be negotiated on a collective basis), our data Trust proposal may remove key obstacles to the realization of the potential underlying large datasets. This article proceeds from an analysis of the very particular type of vulnerability concomitant with our ‘leaking’ data on a daily basis, to show that data ownership is both unlikely and inadequate as an answer to the problems at stake. We also argue that the current of top-down regulatory on contractual freedom is both and the particular type of vulnerability at needed. The latter to a to data subjects when to data governance to the rights by like the GDPR can be as in a to as use of their exercise is both and unlikely to be as when As a governance that is of into the in the we the potential in data Trusts.

The data trust structure supplies the collective-choice and conflict-resolution functions that bilateral consent between an individual and a platform cannot.
“Delacroix and Lawrence (2019) develop the bottom-up data trust as a deliberate alternative to a one-size-fits-all default, arguing for an ecology of trusts with differing terms among which subjects can choose and to which they can defect, so that the trust structure supplies the collective-choice and conflict-resolution functions that bilateral consent between an individual and a platform cannot.”
From Commons-Governed Artificial Intelligence: A Taxonomy of Collective Governance (2026) · cites this paper as Delacroix and Lawrence, 2019
The sections on the Trust structure and social media data describe an ecosystem of trusts with differing terms, subjects choosing among them, and trusts negotiating terms collectively instead of users accepting platform terms individually. The Information fiduciaries section also says subjects can switch trusts. But the paper does not establish the broader claim that the trust structure supplies a conflict-resolution function; its discussion of fiduciary duties and court enforcement is narrower. (LLM, conf=0.83)
Experimental — accuracy not yet measuredExamples of data stewardship include data trusts or cooperatives, which use legal frameworks to formalize collective data management such as data commons or community archives.

From Engaging Communities Meaningfully in Defining Disability Representation for AI Image Generation (2026) · cites this paper as [30]
In “The Trust structure as a way of taking into account the vulnerabilities at stake” (page unavailable), the paper describes a legal Trust that pools data rights and requires a trustee to manage them for beneficiaries. “Information fiduciaries” (page unavailable) says some data Trusts may resemble a collective or cooperative. The passages support the data-trust and collective-management parts, but do not identify data commons or community archives as examples. (LLM, conf=0.84)
Experimental — accuracy not yet measuredThe data layer acquires explicit institutional forms in the bottom-up data trust (Delacroix and Lawrence, 2019) and the data cooperative (Hardjono and Pentland, 2019), and a normative content in the CARE principles (Carroll et al., 2020).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
