Brussels information is about college displaying discredited science (8)
I believe the answer is:
eugenics
'discredited science' is the definition.
'eugenics' can be an answer for 'science' (eugenics is a kind of science). I'm not sure about the 'discredited' bit.
'brussels information is about college' is the wordplay.
'brussels' becomes 'EU' (European Parliament is based in Brussels).
'information' becomes 'gen' (gen can informally mean information).
'about' indicates putting letters inside.
'college' becomes 'c'.
'is' going around 'c' is 'ics'.
'eu'+'gen'+'ics'='EUGENICS'
'displaying' is the link.
Can you help me to learn more?
(Other definitions for eugenics that I've seen before include "Science of human genetic improvement" , "Stock improvement" , "Science of developing animal population through controlled breeding" , "Disputed science" , "Selective breeding by improving genes" .)
