Damage has been done:

They''re lobbying to enforce "AI-literacy", now, obliterating the learning of critical-thinking in kids, just globally-displacing-it with abdication-of-thinking, for their intended totalitarian-dominion.

MAKE ALL SCHOOL-BOARDS KNOW THAT THIS WAS RETRACTED, & WHY!!

Make the research showing that 2/3 of a standard-deviation of REDUCTION in cognitive-performance is pruduced by 5h/day of screentime in kids!!

I asked an LLM for help finding the key paper..

Q: Can you please find me the web-address of the paper which identified that 5h of screen-time reduces kids' cognitive-performance by 2/3rds of a standard-deviation?

The paper you are looking for is titled "Associations between 24 hour movement behaviours and global cognition in US children: a cross-sectional observational study," published in The Lancet Child & Adolescent Health in September 2018.

The study, led by Jeremy J. Walsh and colleagues, analyzed data from the ABCD Study (Adolescent Brain Cognitive Development), involving 4,520 children aged 8–11 years.

Key Finding and Statistics

The researchers evaluated how meeting three specific health recommendations (sleep, exercise, and screen time) impacted cognitive performance. While they found a general decline in performance as screen time increased, the "2/3 of a standard deviation" figure specifically relates to the difference between children meeting all three guidelines and those meeting none:

• The Comparison: Children who met all three guidelines (9–11 hours of sleep, <= 2 hours of screen time, and >= 60 mins of physical activity) had significantly higher global cognition scores than those who met none.

• The Delta: The difference in global cognition between these two groups was approximately 0.65 (roughly 2/3) of a standard deviation.

• 5-Hour Specificity: The study noted that the average screen time was 3.6 hours, but for children reaching high levels of consumption (such as 5+ hours), the cognitive deficit was most pronounced when compared to the baseline of children meeting the 2-hour recommendation.
