This is easy to do for awake or dreaming states, because they are so universally recognized.
Not so for samadhi. The science of measuring samadhi is in its early stage. Right now it is still like a snake chasing its tail- Subjectively, the subject says, "OK I am in samadhi", and the subject is measured. Then the measurement becomes evidence of the state. In an average study, let's say there appears to be correlation between what, 100 subjects? Compared to billions, who I am sure would agree on when they were awake, or dreaming. So maybe Samadhi can be globally agreed upon as a state verified by science. That would be great! But I don't think there is enough consensus on the validity of the studies so far, to say that Samadhi has been scientifically validated.
