"It's probably related to the fact that as far as I know I'm the first person who ever got ialdae to do things. Maybe it's very hard for most people and I'm just especially good at it. You could try studying my lie detection and then seeing if you can copy it - you can see it, right?"

The fact that it's on Matilda makes it a little hard to pick out against the glare, but it's perfectly legible once identified. It's a very tidy little thing, surprisingly elegant for the complexity of its results; rather than having a rigidly defined structure for sorting statements by truth value, it rides on a fuzzy conceptual understanding of what truth means and evaluates statements from both the speaker's and listener's perspective to identify mismatches. The display method is similar to ialdic magic-seeing, but applied to an imaginary written version of spoken statements, never directly interfacing with one's visual field.
