Researchers found that feeding large language models with clickbait and sensationalized posts degrades their reasoning, memory, and ethical behavior, mirroring human effects. This study highlights the risks of using vast web data for AI training, suggesting quality over quantity is crucial to avoid irreversible damage to AI systems.
