More than a decade of exacting scientific research involving paleontological fragments and ancient DNA has lately produced a series of pronouncements about a purportedly novel population of archaic hominins dubbed “the Denisova.” The science involved in these matters is both technically stunning and, socially, at times a bit reckless. Here I discuss the responsibilities which scientists incur when they make inductively risky pronouncements about the different relative contributions by Denisovans to genomes of members of apparent subpopulations of current humans. This (...) science is sensational: it is science which empirically speculates, to the public delight’s and entertainment, about scintillating topics such as when humans evolved, where we came from, and who else we were having sex with during our early hominin history. An initial characterization of sensational science emerges from my discussion of the case, as well as a diagnosis of an interactive phenomenon termed amplified inductive risk. (shrink)

In a recent paper in this journal, Joshua Blanchard has identified a novel problem: the problem of unwelcome epistemic company. We find ourselves in unwelcome epistemic company when we hold a belief that is also held mainly or most prominently by those we regard as morally or epistemically bad. Blanchard argues that some, but not all, unwelcome epistemic company provides higher-order evidence against our belief. But he doesn't provide a test for when company is unwelcome or a diagnosis of why (...) it is unwelcome. I provide both. On my disjunctive test, unwelcome epistemic company provides us with a defeater when either there is a match between the content of the belief and the properties that make our company unwelcome, or there is reason to suspect that the belief arose via a shared, unreliable, causal process.
