naivest

I'm a little stuck... Click here to teach me more about this clue!

'those with the least experience' is the definition.
I can't judge whether this defines the answer.

'vainest' is an anagram of 'NAIVEST'.

'are' acts as a link.

Can you help me to learn more?

(Other definitions for naivest that I've seen before include "Most open" , "very green" , "far from the most wise?" , "Most simple" , "Least sophisticated" .)
