Parallel to the rationality underpinning current science and technology, a set of unfounded beliefs persists among citizens who generally omit scientific criteria to give explanation to seemingly supernatural phenomena. Using the data from the first "National Survey of Social Perception of Science and Technology" (EPSCYT) applied in Chile in 2016, some phenomena in which people believe are explored descriptively and using reasons of probability, and It is analyzed how entrenched they are in the various segments of the population. Among the results, we found a high prevalence in beliefs about the existence of miracles (79%), the spirits (65%), the telepathy (60.2%), numerology (50.4%) and UFO's (59.9%). The discussion raises a paradox of modernity, where despite the propagation of scientific knowledge and technologies, some beliefs in the supernatural are maintained, this even among those who would theoretically be more skeptical, i.e. who have Attained university education, they are adults, they declare themselves agnostics and/or supporters of the thesis of the verification.
