Not sure if that is a thing. From what I’ve been taught:

When you concentrate on something your brain will tend to use familiar thought patterns and not be creative.

When you relax and un-focus you get more creative.

So in a way you can’t try to deliberately come up with ideas. The way around it is to focus on something you want ideas about for a few hours, then get up and do something mindless, have a walk or a bath or something.

Obviously they will be hateful. This should not be enough to consider them guilty however.
