AI reduces a person's logical thinking ability or intelligence over time — especially when compared to their previous cognitive habits.
What Research Says So Far:
- No Direct Measurement of "Reduced Intelligence" Yet
There is no conclusive research that quantifies exactly how much intelligence is reduced when someone switches from using their own logical thinking to relying heavily on AI tools. But there are concerns and observations in related areas:
What is Being Observed?
A. Cognitive Offloading
When people use calculators, GPS, or AI tools, their brains “offload” work.
Research shows cognitive offloading can lead to reduced memory, problem-solving, and critical thinking over time.

B. AI and Decision-Making Bias
Users often over-trust AI-generated answers, even when they’re wrong.
This can make users less likely to use their own reasoning.

C. Skill Atrophy
Just like muscles weaken without exercise, unused cognitive skills can decline.
If users no longer practice logic, their logical reasoning abilities can diminish.
🧠 BUT — It’s Not All Negative
AI can also:
Enhance learning when used with logical thinking.
Help people test and refine their ideas.
Be a partner in critical thinking (if used mindfully).
So, it’s how we use AI that determines whether our intelligence is supported or dulled.
🧪 Has Exact Intelligence Reduction Been Measured?
Not exactly. No standardized IQ test has been used in a large study before-and-after AI usage to measure decline.
However, indirect studies show declines in:
Problem-solving
Attention span
Creative reasoning
When relying heavily on AI without self-engagement.
There is no fixed number or percentage of intelligence loss proven by science.
But long-term overuse of AI without active thinking may weaken logical skills.
