J. Robert Oppenheimer

IQ: 135

🔍 How Did We Calculate This?

Note: Like Einstein, Oppenheimer never undertook a formal IQ test, yet his significant contributions to physics lay a solid foundation for this estimate.

1️⃣ Understanding the Flynn Effect:

Acknowledging the Flynn Effect, which indicates a rise in IQ scores over time, the average IQ during Oppenheimer's era was around 70.

2️⃣ Modern Baseline:

A peer-reviewed article suggests the modern average IQ for physicists is 133.

3️⃣ Historical Baseline:

Hence, the average physicist IQ of that time would be around 100.

4️⃣ Estimating the Number of Physicists in the Early 1900s:

Historical data estimates about 3,000 physicists worldwide at that time.

5️⃣ Utilizing Normal Distribution:

Assuming a normal distribution with a mean IQ of 100 and a standard deviation of 15, Oppenheimer, placed within the top 1% of physicists, would likely fall at the 99th percentile (30/3000). This corresponds to a Z-score of approximately 2.33.

6️⃣ Estimating Oppenheimer's IQ:

Utilizing this Z-score and the formula IQ=mean+(Z×SD), Oppenheimer's estimated IQ comes out to be 135.
