 Philosophers continue to debate the implications of this complicated and evolving empirical picture. Some have explored how such evidence may be put to use by experimental philosophers engaged in positive substantive projects of explication and conceptual engineering (Shepherd &amp; Justus 2015; Schupbach 2017; Nado 2021). Even when intuitions about philosophical cases do not significantly vary, systematic investigation of them may still yield important evidence in the analysis of concepts (Stich &amp; Tobia 2016, also see Knobe 2016 and Machery 2017).
