In recent years, there has been considerable interest in studying and using scientific consensus messaging strategies to influence public opinion. Researchers disagree, sometimes vociferously, about how to examine the potential influence of consensus messaging, debating one another publicly and privately. In this essay, we take a step back and focus on some of the important questions that scholars might consider when researching scientific consensus messaging.Hopefully, reflecting on these questions will help researchers better understand the reasons for the different points of debate and improve the work moving forward.

Different chemical species are often cited as paradigm examples of structurally delimited natural kinds. While classificatory monism may thus seem plausible for simple molecules, it looks less attractive for complex biological macromolecules. I focus on the case of proteins that are most plausibly individuated by their functions. Is there a single, objective count of proteins? I argue that the vagaries of function individuation infect protein classification. We should be pluralists about macromolecular classification.

Talk of different types of cells is commonplace in the biological sciences. We know a great deal, for example, about human muscle cells by studying the same type of cells in mice. Information about cell type is apparently largely projectible across species boundaries. But what defines cell type? Do cells come pre-packaged into different natural kinds? Philosophical attention to these questions has been extremely limited [see e.g., Wilson (Species:

Science communication via testimony requires a certain level of trust. But in the context of ideologically-entangled scientific issues, trust is in short supply -particularly when the issues are politically "entangled". In such cases, cultural values are better predictors than scientific literacy for whether agents trust the publicly-directed claims of the scientific community. In this paper, we argue that a common way of thinking about scientific literacy -as knowledge of particular scientific facts or concepts -ought to give way to a second-order understanding of science as a process as a more important notion for the public's trust of science.
