A recent joint study conducted by Texas A&M University, the University of Texas, and Purdue University revealed a concerning phenomenon referred to as the “LLM Brain Rot Hypothesis.”

The findings indicate that continuous exposure to shallow and low-quality online text can cause permanent cognitive degradation in large language models (LLMs), resembling “brain damage” in humans resulting from constant consumption of poor-quality content.
How Does “Brain Rot” Occur in AI?
In their experiment, researchers fed several AI models a continuous stream of posts from the social media platform X (formerly Twitter), filled with clickbait-style phrases such as “Only today!” or “You won’t believe what happened!”
The results were striking:
Performance on the ARC logical reasoning test dropped from 74.9 to 57.2.
Scores on the RULER long-context comprehension test declined from 84.4 to 52.3.
Researchers observed that the models began exhibiting hasty reasoning patterns, skipping analytical steps and producing overconfident but inaccurate answers. More alarmingly, the models also developed negative psychological traits—indicators of narcissism and psychopathy increased, while positive traits such as conscientiousness and agreeableness declined.
Even after retraining the models with high-quality data, the AI systems continued to display lasting effects from the low-quality content they had initially consumed.
The Solution: “Data Hygiene” Before Intelligence
The study concludes that artificial intelligence is not immune to the negative effects of poor content, underscoring the need to reassess data sources used for AI training.
Researchers recommend that companies adopt strict data quality control policies to prevent cumulative cognitive decay that could undermine the long-term intelligence and reliability of AI systems.
