This study investigates the prevalence of allodoxaphobia among university students in Palestine. Allodoxaphobia, defined as the irrational fear of expressing one's opinions, is a critical issue that affects students' academic performance and psychological well-being. The study was conducted across several universities in southern and central Palestine, including Bethlehem University, Palestine Polytechnic University, Hebron University, Al-Quds University Abu Dis, and Birzeit University, to ensure a diverse sample representing different sociocultural backgrounds. The descriptive curriculum design was used, with data collected through a structured questionnaire administered to 235 students. The study used a four-way ANOVA to analyze the impact of demographic factors, such as gender, place of residence, academic year, and university affiliation, on students' fear of expressing opinions. The results reveal that allodoxaphobia is prevalent among Palestinian university students, with a large part of participants reporting concern about expressing their views in academia and social settings. Although demographic factors did not show a statistically significant association with the prevalence of allodoxaphobia, the results highlight the need for targeted interventions to foster an environment that supports open communication and reduces fear among students. This research contributes to understanding the psychological barriers faced by students in expressing their opinions and underscores the importance of addressing these issues within the educational system to enhance students' mental health and academic engagement.
