Ever asked ChatGPT to pick a random number between 1 and 100? If yes, there's a good chance it answered with 73.

The trend has been noticed by users worldwide, sparking curiosity about whether the AI has a favourite number. The reality is more interesting.
Unlike a random number generator, ChatGPT doesn't actually "roll a dice." It predicts the most likely response based on patterns it has learned from vast amounts of text and human conversations.

Experts believe 73 appears frequently because humans often perceive it as a random-looking number. It's an odd prime number, not too small, not too large, and avoids obvious choices such as 50 or 100.
The number also gained popularity through pop culture after a famous episode of The Big Bang Theory, where Sheldon Cooper described 73 as "the best number."

The phenomenon highlights a key fact about artificial intelligence: AI systems often reflect human preferences and biases hidden within their training data. So when ChatGPT repeatedly picks 73, it isn't being truly random - it's following patterns learned from people.
In short, the next time ChatGPT says 73, remember that the choice reveals as much about human behaviour as it does about artificial intelligence.
