University studies do not always influence students' critical thinking skills. A doctoral thesis recently defended at the UIB analyzed this question with a sample of 6,584 students to determine whether higher education acts as a barrier to paranormal beliefs, such as faith in astrology, amulets, or the effects of the moon on behavior. The results of Hugo Blázquez Matas's doctoral thesis are surprising: almost half of the students accepted at least one paranormal belief, and 18% were classified as "strong believers." The most widely held beliefs were the effects of the moon (22%) and religious beliefs (17%), while astrology and omens had fewer followers.
