We do not telepathically receive experiemnt results when they are performed. In reality you need ot intake the measumrent results from your first-person point of view (use eyes to read led screen or use ears to hear about stories of experiments performed). It seems to be taht experiments are intersubjective in that other observers will report having experiences that resemble my first-hand experiences. For most purposes shorthanding this to "public" is adequate enough. But your point of view is "unpublisable" in that even if you really tried there is no way to provide you private expereience to the public knowledge pool ("directly"). "I now how you feel" is a fiction it doesn't actually happen.

Skeptisim about the experiencing of others is easier but being skeptical about your own experiences would seem to be ludicrous.
