Understanding shifting perceptions of nanotechnologies and their implications for policy dialogues about emerging technologies
Bibliographic record
Abstract
Communications from scientists and engineers indicate concern about the potential for public aversion to nanotechnologies. Recommendations that policy dialogues occur early and often as public perceptions emerge have followed, and multiple surveys indicate high benefit ratings. This paper explores instead the mobile and conditional quality of current perceptions of the risks and benefits of nanotechnologies, and of judgments of trust in regulation. Drawing from a nationally representative phone survey of 1,100 US residents, we found that presenting risk information after benefit information had a significant impact on acceptability ratings as compared to the reverse order. Trust judgments were also mobile, and interacted with affective predispositions towards nanotechnologies. Overall, for policy purposes and dialogues, we find high attitudinal uncertainty suggesting considerable openness to context-specific considerations as linked to acceptability of new technologies. We also caution against over promotion of benefits and an avoidance of appropriate risk discussions in the short term.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
