I'm reading "Hell Hath No Fury" by Weber and Evans right now, and it had an interesting bit on bias.
In 'HHNF', there are two multiversal civilizations which use interdimensional portals to expand out into virgin Earths. And they bumped into each other, and things went south dramatically.
One side has psionic Talents, and the other side has what they call magic Gifts. One of the Talents, a Voice (aka a long-range and short-range mindreader and mindsender) and her husband were captured by the opposing side, and are being brought through many dimensions and across tens of thousands of miles of 'railroad' to the home dimension.
And one of the features of a Voice link is that the Voice can pick up a little of the emotions and such, the sideband, of the true message. This sideband is weakening after they got deeper into enemy territory.
The protagonists' initial off the cuff theory was that Talents got weaker after a prolonged exposure to the Gifted. I, of course, instantly thought of Bias, of the rules in dimensions changing.
"HHNF" could be similar to the Triverse in this, but with a more subtle breakdown and rebuilding of bias that stretches over a dozen dimensions between the two areas most amenable to their own type of power.

Also, they did something like what you did with TK, where you broke it up into varying parts. There are Voices, and there are Sifters (who can tell if you lie), and some other type of talent which lets you feel the type of person the other person is, and their general leaning at that time. As the character in the book puts it...He feels like he's about to stick a dagger in your ribs and get away with it.
And you have Distance Viewers who are the top, and then there are Mappers who can show an area, and Plotters who can show the living in an area.

This is in large part an FYI post.
