Fine. You tell me what psi is. I'm not asking for a big theory or mechanism, just an operational definition. What do people mean when they say it?


The term psi denotes anomalous processes of information or energy transfer, processes such as telepathy or other forms of extrasensory perception that are currently unexplained in terms of known physical or biological mechanisms. The term is purely descriptive: It neither implies that such anomalous phenomena are paranormal nor connotes anything about their underlying mechanisms.


- Bem, D. J., & Honorton, C. (1994). Does psi exist? Replicable evidence for an anomalous process of information transfer. Psychological Bulletin', 115, 4-18. (from Wikipedia)

Alright, so this defines psi as any of these:
    anomalous information/energy transfer
    telepathy
    ESP
How are these defined? Just one will suffice, I think.
Defining something in terms of something that´s also undefined terms is not helpful.

BTW there are other definitions of psi which directly contradict that one.

Even for an informal definition we have to apply some kind of filter to "what people mean when they say it", else "science" would include or fall under "magic", too.

I don't understand this sentence.
