What is sentiology?

[kelsoftx]

I've been to this other place where they tried to introduce me to sentiology but I just couldn't understand what really it deals with. Is it something related to psychology? If yes/no, how do the two differ?

Sent - iology, is it something to do with the mail?

They mean Scientology, the stuff by L. Ron Hubbard.
