That's a fun way to put it! The phrase "it's not rocket science" implies something is relatively simple. Here's why intuition doesn't fit that description:

* Intuition is a complex process: Intuition is a blend of subconscious pattern recognition, past experiences, emotions, and sometimes even gut feelings. It's not a straightforward calculation like a rocket equation.

* Intuition can be unreliable: While often helpful, intuition can lead us astray. It's based on incomplete information and biases, so it's not always accurate.

* Rocket science requires rigorous logic: Rocket science demands precise calculations, scientific understanding, and meticulous engineering. It's a highly structured and logical field.

So, why do we say "it's not rocket science"?

We use this phrase to emphasize the simplicity of a task compared to the highly complex field of rocket science. In essence, it's a way of saying, "It's not as hard as you think."

In conclusion: Intuition is a valuable tool, but it's not a reliable substitute for careful analysis and critical thinking. Rocket science, on the other hand, relies heavily on those things, making it a much more rigorous field.
