Consider it poor judgement (10)
I believe the answer is:
discretion
'judgement' is the definition.
(discretion is a kind of judgement)
'consider it poor' is the wordplay.
'poor' indicates anagramming the letters.
'consider'+'it'='considerit'
'considerit' is an anagram of 'DISCRETION'.
(Other definitions for discretion that I've seen before include "The better part of valour" , "Tactful quality" , "Liberty to act at pleasure; prudence" , "Freedom to decide on an action" , "Diplomacy" .)
