# Over-reliance on chatbots can diminish critical-thinking skills, study finds

> **Open Intelligence Dossier** · First detected: 2026-06-20 10:07 UTC · Category: Technology

## Executive Summary
New research warns that leaning on chatbots may erode critical thinking and even heighten dementia risk.

## Intelligence Brief
A 2025 study of over 600 people found a correlation between leaning on AI tools and weaker critical‑thinking skills, with the sharpest decline observed among younger users. Coverage highlights the potential neurological cost, with a neuroscientist warning that outsourcing thinking to AI may weaken the brain against dementia.


Outlets such as Moneycontrol.com, Fast Company, MIT Media Lab, Space Daily, Tech Policy Press, Yahoo and The Guardian frame the issue as a cognitive surrender that could have broader societal impacts. Future reporting will track additional research on AI’s cognitive effects and any emerging policy or educational responses aimed at mitigating the hidden costs of over‑reliance on chatbots.
