This article aims to shed light on what lies at the heart of skepticism towards counterfactual, alternative, or what-if history. On its face, counterfactual history gives historians and philosophers good reason to worry. First, because counterfactual pasts leave no traces, historians lack an important source of empirical warrant. Second, because rewriting historical events might unpredictably change the past, inferences about what might have happened seem only weakly supported by generalizations about what actually did happen. Third, counterfactual narratives appear especially vulnerable (...) to wishful thinking. Ultimately, through consideration of the epistemic values that regulate the construction of counterfactual narratives, I marshal arguments against these objections and defend the legitimacy of the project. Still, I hope to show that far from being a mere ‘parlor game’, counterfactual history raises deep and provocative questions about historians’ ability to know our past, only some of which I address here.

Policies that require male-female sex comparisons in all areas of biomedical research conflict with the goal of improving health outcomes through context-sensitive individualization of medical care. Sex, like race, requires a rigorous, contextual approach in precision medicine. A “sex contextualist” approach to gender-inclusive medicine better aligns with this aim.

Based on the Competition Model, the current study investigated how cue availability and cue reliability as two important input factors influenced second language (L2) learners' cue learning of the English article construction. Written corpus data of university-level Chinese-L1 learners of English were sampled for a comparison of English majors and non-English majors who demonstrated two levels of L2 competence in English article usage. The path model analysis in structural equation modeling was utilized to investigate the relationship between the input factors (...) and L2 usage (frequency and accuracy of article cue production). The findings contribute novel and scarce empirical evidence that confirms a central claim of the Competition Model, i.e., the changing importance of cue availability and cue reliability in the frequency and accuracy of production. Cue availability was found to determine L2 production frequency regardless of level of L2 competence. Cue reliability was the input factor that differentiated competence levels. When learners stayed at a relatively lower L2 proficiency, cue reliability played an important role in influencing L2 frequency of usage rather than accuracy of usage. When learners developed increased exposure to and stronger competence in the target language, cue reliability played a significant role in determining learners' success of cue learning. The study is methodologically innovative and expands the empirical applicability of the Competition Model to the domain of second language production and construction learning. (shrink)
