What is the IQ of a PHD in physics?

Published in Academic Intelligence 2 mins read

The IQ of a person with a PhD in physics is generally around 130 or 140.

IQ and PhD Studies

It's commonly understood that pursuing a PhD requires significant intelligence. While hard work is essential, having a high IQ is also a contributing factor to success in such rigorous academic fields. Here's a breakdown:

  • General PhD IQ Ranges: Studies show that individuals with PhDs in most subjects tend to have IQ scores in the range of 120–130.
  • Physics and Math Exception: Specifically in physics and mathematics, the IQ scores are typically higher, reaching around 130 or 140, according to the provided reference.
  • IQ Test Variations: These scores can vary slightly depending on the specific IQ tests used in the studies.

Why the Higher IQ in Physics?

There is a common theory that people who choose a PhD in physics or mathematics are naturally inclined towards more complex problem-solving which requires higher-level cognitive abilities which are often measured by IQ tests.


Field Typical IQ Range
Most PhD Subjects 120–130
Physics & Math 130-140


It’s important to note that IQ is just one factor influencing academic achievement and success, but it does provide a general idea of the cognitive abilities associated with specific academic pursuits.
