Philosophy
Her book Tracking Truth presents a unified treatment of knowledge, evidence, and epistemological realism and anti-realism about science, based on the idea that knowing is responsiveness to the way the world is, and that this is an ability to follow the truth through time and changing circumstances. Responsiveness is defined for empirical knowledge by a reformulation of Robert Nozick’s tracking conditions—for example: if p were false, then S wouldn't believe p—using conditional probability instead of counterfactuals. Roush argues that the new tracking view is superior to other externalist views of knowledge, including process reliabilism. Of particular interest are the new view's fallibilist account of knowledge of logical truth, its treatment of reflective knowledge and lottery propositions, its solutions to the value problem and the generality problem, its implications about skepticism, and its explanation of why knowledge is power in the Baconian sense.
In the second half of the book it is argued that the tracking theory of evidence is best formulated and defended as a confirmation theory based on the Likelihood Ratio. The tracking theories of knowledge and evidence thereby fit together to provide a deep explanation of why having better evidence makes you more likely to know.

Why this record matters
“Sherrilyn Roush” is worth following because a concise public description often conceals a longer documentary argument. Here, Sherrilyn, Roush and American provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Dec 25, 2025. The linked authority identifier is Q7495367. VIAF identifies the subject as 49511318. The Library of Congress control number is no2006017323. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2014, 1999, 2006 and 2018.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
