Feels almost like the setup for a horror story. It turns out everyone's inner monologue is saying absolutely terrifying things, but then we just immediately forget. Schizophrenia turns out to just be the ability to remember and notice the things we're all saying.

And with that thought, I wonder if this sort of technology might be really useful for people with intrusive thoughts or schizophrenia, etc. Being able to objectively measure how well any given medication or therapy is working feels like a win to me.
