The Flynn effect, which advocated that there was a rise in the global IQ score, was widely accepted by the relevant scientific community. However, there are recent research findings that this effect has been reversed. In this study, both Flynn and anti-Flynn effects were investigated. The purpose of this study is to analyze students' general, verbal, and visual intelligence score trends in the last six years (range = 2016--2021). The participants of the study included 2192 students who were in first grade in elementary school by the time of data collection. The Anadolu-Sak Intelligence Scale (ASIS) was used to measure the full-scale IQ, verbal IQ, and visual IQ scores of the participants. Participants' mean general, verbal, and visual intelligence scores in different years were analyzed by trend analysis. The research findings showed that there was a descending trend in general, verbal, and visual scores between the years 2016 to 2021. Moreover, our findings reveal that there is a sharp decrease in IQ score trends between 2020 and 2021. Because of this study, the Flynn effect could not be seen in the way that was predicted.
