The works gathered in this collection entitled "Scientific initiation in the fight against negative ideas" were selected as the best articles presented in each of the thematic areas of the VIII Research Meeting and XII Scientific Initiation Meeting of the Faculty of Telêmaco Borba, held on October 27-29, 2021. Thus, both the event that gave rise to the publication and the collection presented here are part of an institutional policy to support academic research, especially scientific initiation, promoting it as an educational principle that motivates pedagogical practice in the university context, seeking to develop a permanent capacity for reconstructive questioning for human and professional training, in order to train competent individuals committed to the search for solutions to the challenges of the contemporary world, who know how to find and propose solutions through research, that is, professionals with sensitivity, creativity and competence to identify problems, build and rebuild answers.
