New analysts say less but have a bias (5)
I believe the answer is:
slant
'a bias' is the definition.
(I know that slant is a more specific form of the action bias)
'new analysts say less' is the wordplay.
'new' indicates an anagram.
'less' suggests deleting specific letters (less can mean minus).
'analysts' with 'say' removed is 'nalts'.
'nalts' is an anagram of 'SLANT'.
'but have' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for slant that I've seen before include "Lie obliquely" , "Inclination" , "Angle; incline" , "Slope - bias" , "Angle; make oblique" .)
