How many geniuses are in the world?

Estimating the number of geniuses in the world is challenging, as "genius" can be defined in various ways, often related to exceptionally high IQ scores or extraordinary accomplishments in specific fields. Generally, it is believed that about 0.1% of the population qualifies as "genius" based on an IQ score of 140 or above. With the global population exceeding 8 billion, this suggests there could be several million individuals who might be considered geniuses by this standard. However, genius can also manifest in diverse talents and skills beyond just IQ, making it difficult to quantify accurately.
