I wonder if 'negatively biased' in the following sentence could mean 'bringing up negative associations':
John is guilty is understood through a cognitive schema referring to the negatively biased core supposition, 'guilt'.
Just as, say, if I used the word 'happy' about someone, your view of the person would be positive and very different than if I had said 'surly' or 'unfriendly'.
To use words like 'thief', or 'murderer' in relation to someone is to bias your judgment about them negatively; and 'guilty' brings up the associated thoughts of crime/police/what did he do?/prison.
