This paper investigates readers' recognition of unsourced evidentials in texts in association with critical reading. To this end, we involved four Iranian postgraduate students at an Australian university in a collective case study where each student read four Persian texts and participated in in-depth interviews and focus group discussions. Data analysis employed critical discourse analysis and discursive power relations to examine participants' positionalities and subjectivities. Our findings in general confirm the students' recognition of unsourced evidential in texts as an indication of critical reading. More specifically, it was revealed that linguistic sources (e.g. Persian indefinite suffix '-i'), as well as socio-cultural factors such as normalization embedded within the Persian oral narrative and discourse, play significantly in identifying unsourced evidentials. Pedagogical implications for critical reflection on texts containing instances of unsourced evidentials are suggested.
