How do you use idiocy in a sentence?

"The idiocy of the plan was evident from the start, as it relied on a series of unrealistic assumptions."

Here's why this works:

* Idiocy is a strong word that implies foolishness or stupidity.

* The sentence clarifies the idiocy by explaining the unrealistic nature of the plan.

Note: While "idiocy" is a strong word, using it carefully can emphasize the point you're making. However, be mindful of the connotations of the word and choose your language appropriately.
