Bullied into releasing a sweeping statement (14)
I believe the answer is:
generalisation
'sweeping statement' is the definition.
(I've seen this before)
'bullied into releasing a' is the wordplay.
'bullied' indicates anagramming the letters.
'into'+'releasing'+'a'='intoreleasinga'
'intoreleasinga' anagrammed gives 'GENERALISATION'.
(Other definitions for generalisation that I've seen before include "sweeping statement" , "that has nothing specific to say" .)
