Overall ethical score
+83.82
Reasoned summary
Carson's ethical contribution was exceptionally positive: she made complex evidence understandable, exposed preventable harm and did so without fabricating certainty or demanding indiscriminate prohibition.
This assessment presents six separate ethical dimensions rather than one overall moral score. Each result must be read with its evidence, plausible range, confidence, disputes, exclusions, severe-harm findings and sources.
Most significant negative evidence
The score is moderated because later policy outcomes were produced by many actors and because pesticide restriction can also create trade-offs for disease control and agriculture.
