Prejudice one noticed in graduate, baseless ultimately (4)
I believe the answer is:
bias
'prejudice' is the definition.
(I know that prejudice can be written as bias)
'one noticed in graduate baseless ultimately' is the wordplay.
'one noticed' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'in' means one lot of letters goes inside another.
'graduate' becomes 'BA' (someone with a Bachelor of Arts degree).
'ultimately' indicates one should take the final letters.
The last letter of 'baseless' is 's'.
'i' put into 'ba' is 'bia'.
'bia'+'s'='BIAS'
Can you help me to learn more?
(Other definitions for bias that I've seen before include "One-sided prejudice" , "(Bowls) irregular shape" , "Spin" , "Prejudiced or weighted opinion" , "Favouritism" .)
