Turns to organisation without seeing the evidence (2,5)

I believe the answer is:

on trust

'without seeing the evidence' is the definition.
(as in taking something on trust)

'turns to organisation' is the wordplay.
'organisation' indicates an anagram.
'turns'+'to'='turnsto'
'turnsto' with letters rearranged gives 'ON TRUST'.

(Another definition for on trust that I've seen is " accepted without question".)

I've seen this clue in The Guardian.
