Abstract

We present three experiments that explore the robustness of the _authentic-apparent effect_—the finding that participants are less likely to attribute knowledge to the protagonist in apparent- than in authentic-evidence Gettier cases. The results go some way towards suggesting that the effect is robust to assessments of the justificatory status of the protagonist’s belief. However, not all of the results are consistent with an effect invariant across two demographic contexts: American and Indian nationalities.
