Are We Getting Dumber? The Surprising Trend of Declining IQ Scores

Are We Getting Dumber? A Look at Declining IQ Scores Spain - A recent video by Àlex Letosa has sparked debate about the global trend of declining intelligence quotients (IQs). Letosa's video, which has garnered significant attention online, presents data suggesting a decrease in IQ scores in many countries since 1990, contrasting this with the sustained rise in IQ seen in Japan. The video uses graphs to visually represent this trend. "From 1960 to 1990, the IQ shot up. But from 1990 to 2020, it hasn't stopped falling," Letosa states in the video. He attributes this decline to a lack of cognitive effort and poor diet in many parts of the world. The video highlights Japan's success in maintaining a rising IQ, suggesting that investment in education and good nutrition plays a crucial role. While Letosa's claims are certainly thought-provoking, experts caution against drawing definitive conclusions from the presented data. Further research is needed to verify the accuracy and scope of the trends. Nevertheless, the video serves as a valuable stimulus for discussion on the factors influencing cognitive abilities and the importance of education and healthy lifestyles.
