Oppenheimer's IQ is 135. This estimation assumes he would be among the top 1% of living physicists during his era. The estimation follows the methods and assumptions utilized for Albert Einstein, offering a credible insight into Oppenheimer's intellectual caliber.
In 2024, the film "Oppenheimer," directed by Christopher Nolan, was a standout at the Oscars, winning several awards including Best Picture and Best Director. Cillian Murphy's portrayal of J. Robert Oppenheimer was also highly acclaimed. The film's success at the Oscars further underscores the profound impact of Oppenheimer's intellect on both the scientific and cinematic worlds[source].

Note: Like Einstein, Oppenheimer never undertook a formal IQ test, yet his significant contributions to physics, coupled with his undergraduate degree from Harvard in the USA and PhD from the University of Göttingen in Germany, lay a solid foundation for this estimate.
Acknowledging the Flynn Effect, which indicates a rise in IQ scores over time, the average IQ during Oppenheimer's era was around 70.
A peer-reviewed article suggests the modern average IQ for physicists is 133.
Hence, the average physicist IQ of that time would be around 100.
Historical data estimates about 3,000 physicists worldwide at that time.
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.
Oppenheimer's IQ is 135. It is a result of the Z-score of 2.33 and the formula IQ=mean+(Z×SD), 100 + (2.33x15) = 135.
