Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q1 i? Many PETs explicitly trade utility for privacy, and some applications such as mandated reporting requirements cannot accommodate these compromises. → tradeoff-1
Evidence¶
tradeoff-1¶
Dorie, Vincent. (2025, December). Privacy enhancing technologies in digital learning platforms. Digital Promise. https://doi.org/10.51388/20.500.12265/278
q1 · i? · theoretical · r2
Authors' argument in the PET Limitations section: there are many applications where these compromises are too great, with mandated reporting requirements given as an example, so opportunities to use PETs are limited. This is an interpretive claim, not a tested result.
"Finally, many PETs provide their enhancements by explicitly trading utility for privacy: data is harder to access, or always encrypted, or purposefully inaccurate, etc."
Discussion¶
Related Claims¶
- PETs expand the value of data by enabling sharing where in-the-clear approaches are infeasible — related
- SEERNet platforms trade off open science against availability of individual student data, with eTrials and ASU L@S at opposite extremes — a narrower finding that bears on this claim
