Treating only one side of evidence is bad? (6)
I believe the answer is:
biased
'bad?' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'treating only one side of evidence' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'side' could be 'base' (base is a kind of side) and 'base' is located in the remaining letters.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'is' is the link.
Can you help me to learn more?
(Other definitions for biased that I've seen before include "Favouring one person or side over another" , "Prejudiced or influenced in favour or against" , "favouring a particular idea" , "Having favourite" , "Influenced unfairly" .)
