"One might think that the day will come in which scientists have so precisely correlated mental and brain states that a scientist could, indeed, know better than I what is going on in my mental life by simply reading my brain states. But in order to develop a detailed chart correlating specific mental and physical states, you must ask your experimental subjects what is going on inside them as he reads the brain monitor. So any such correlation will be epistemically dependent on and weaker than a subject's own introspective knowledge of their conscious states because the chart depends on the accuracy of experimental subjects' reports of their own consciousness."
