Puts out paper opposing current tendencies (8)
I believe the answer is:
upstream
'opposing current tendencies' is the definition.
(I've seen this before)
'puts out paper' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'paper' becomes 'ream' (I've seen this before).
'puts' anagrammed gives 'upst'.
'upst'+'ream'='UPSTREAM'
(Other definitions for upstream that I've seen before include "Going back to the source" , "Away from the sea" , "Current trend is not" , "contraflow" , "Towards (river's) source" .)
