Public scientific testimony in the scientific image
Open accessAbstract
In this paper, I draw on philosophy of science to address a challenge for science communication. Empirical research indicates that some people who trust a meteorologist's report that they are in the path of a storm do not trust a climate scientist's report that we are on a path to global warming. Such selective skepticism about climate science exemplifies a more general challenge:A prominent response arising from the novel interdisciplinary science of science communication is a principle called Consensus Reporting. According to this principle, science reporters should, whenever feasible, report the scientific consensus or lack thereof for a reported scientific view. However, philosophy of science may offer a different perspective on the issue. This perspective is critical insofar as it indicates some inadequacies of Consensus Reporting. But it is also constructive insofar as it guides the development of an alternative principle, Justification Reporting, according to which science reporters should, whenever feasible, report aspects of the nature and strength of scientific justification or lack thereof for a reported scientific view. A central difference between these proposals is that Consensus Reporting appeals to the authority of the scientists whereas Justification Reporting appeals to the authority of scientific justification. As such, Justification Reporting reflects the image of science. The paper considers the philosophical and empirical motivation for Justification Reporting and its limitations. This includes prospects and problems for implementing it in a way that addresses The Challenge of Selective Uptake. From a methodological point of view, the paper illustrates how empirically informed philosophy of science may help address challenges for science communication.

The RM account can explain why confirmation bias is particularly strong in groups in which shared ideologies are at stake.
“The account can also explain why confirmation bias is particularly strong in groups in which shared ideologies are at stake (Taber and Lodge 2006;Gerken 2019).”
From What Is the Function of Confirmation Bias? (2022) · cites this paper as Gerken 2019
The accepted manuscript (pp. 9–10) describes motivated cognition as favoring antecedent views and says identity-protective cognition may explain backfire effects in groups whose social identities are implicated. It does not establish that confirmation bias is generally *particularly strong* in such groups; on p. 19, it cautions against overestimating backfire effects. (LLM, conf=0.82)
Experimental — accuracy not yet measuredThe PST generality constraint fits well with, and can supplement, other recent guidelines that aim to prevent ethical or epistemic harm from PST.
“PST generality constraint also coheres well with, and can be added to, other recently defended guidelines for scientists and science reporters to avoid causing ethical and/or epistemic harm via PST (see, for example,Gerken [2018Gerken [ ], [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.
