Trope-a-Day: Mind Probe

Mind Probe: Available in a couple of forms; the alethiometer, a highly sophisticated lie detector which works by dynamic mind-state analysis, and the more advanced form, which is obtaining a static copy of the mind-state (via Brain Uploading, which fortunately is possible non-destructively these days) and dissecting it for whatever information you need.¬† Since this latter is being done on a separate non-running copy of the target’s mind, it has the advantage (for them) of not causing hallucinations, pain, or brain damage, but also the disadvantage (for them) of being entirely irresistible by anything they can do.
