>It also induces different states by way of imperceptible stimuli and measured the response

Are you sure? Am I missing that part? I see this:

>Other tricks to infer cognitive state involved quickly flashing visuals or sounds to a user in ways they may not perceive, and then measuring their reaction to it.

But that doesn't say they're inducing states but rather trying to figure out the state. Trying to understand if someone is mad does not seem quite as dystopian as trying to make someone mad.

If you have the capability to measure state, and you have control over audio / visual input, then you necessarily have the ability, albeit via a probably alarmingly small number of experiments, to induce (some value of) state.

Lacking an understanding of the mechanism, I'm not sure I understand how that necessarily follows regardless of the mechanism. Completely pulling something out of my ass, imagine that they determine inserting occassional white frames results in more significant pupil dilation increases when someone is in a heightened emotional state. Sounds doable and vaguely plausible? It would allow them to infer that heightened emotional state from a quickly flashed visual in a way most users likely wouldn't perceive from a measured reaction to it. But I'm missing how it would follow that you could use the same to cause that emotional state.

Classical conditioning has been known since Pavlov and his experiment with a dog.
