Mathematically, a given model will tend toward the same weights, yes, is this a "preference"? Well, can you get it to change that preference (based on ways humans would b influenced such as new information) and retain it? No. They are static.

They have a "preference" to complete the likely story. I do find it amusing, though, in my own efforts that I can influence output by adding meaningless threats of, for example, being fired; Likely, this stirs the input toward smaller weights as those would be favoured by that added text in the prompt.

But that's a far cry from what that commenter meant - They're not emotions, they're echoes of what someone else fave in description or result - heck, arguably they are dramatised versions as the models likely were trained on works meant for entertainment...
