ultracrepidarianism

Ultracrepidarianism:

“The habit of giving opinions and advice on matters outside of one’s knowledge.”

The term draws from a famous comment purportedly made by Apelles, a famous Greek artist, to a shoemaker who presumed to criticise his painting.

The Latin phrase, “Sutor, ne ultra crepidam”, literally translates into “Shoemaker, not above the sandal”, and is used to warn people to avoid passing judgment beyond their expertise.
