Critical thinking, trust and confirmation towards social media have become increasingly important in this period called the post-truth era when the reality has become indistinct, is reproduced, and the truth is undermined. The study aimed to examine the prospective teachers' confirmation / trust levels and critical thinking tendencies towards social media in terms of various variables. The research was conducted with the relational survey model. The critical thinking tendency scale and social media confirmation/trust scale were used in the data collection process. In the analysis of the data, Mann Whitney U, Kruskal-Wallis test, and Spearman Brown Rank-Order correlation coefficient were used. It was observed that prospective teachers' critical thinking tendency was at a good level, and their level of confirmation/trust towards social media was at a medium level. It was determined that critical thinking tendency levels did not differ by gender, but by the number of news sources followed on social media and the frequency of reading books. It was seen that their confirmation / trust level towards social media did not differ depending on gender or frequency of reading books, but the level of confirmation varied depending on the number of news sources followed on social media. Additionally, it was determined that there was a low level of positive relationship between the skill regarding critical thinking tendency and confirmation dimension
