The term psionic is analagous to bionic. Where bionic means biological + electronic, psionic means psychic + electronic; it originally referred to sci-fi technology for amplifying psychic powers. (Read Poul Anderson's Call Me Joe for an example.)
I'm not sure how this is an objection to my assertion. Perhaps you are just assuming I'm unaware of some fo the details, or perhaps you are just trying to amplify what I just said?
The term psychic is itself modern and pseudo-scientific, created in the late 1800s to lend a scientific air to the same magical beliefs that had existed since pre-history.
Right. So, 'psionic = psychic = magic' by your own description. Certainly in no edition of D&D have 'psionic powers' been associated with electronic augmentation, nor is that the most salient feature of even most science fiction uses of the phrase.
In stories with science fiction genera trappings, 'psionics' are usually used as a form of genera sleight of hand, to distract the reader or audience from the invocation of magic by dressing that magic in psuedo-scientific garb and give it a scientific air.
This however is not how they are used in fantasy settings. For example, in D&D, psionics were originally functionally used to represent essentially a native magical power that wasn't tied to character level (and hense study, experience, or profession). The continued existence of the idea of 'psionics' in the D&D fantasy setting where this function isn't fulfilled is somewhat odd, and really is nothing more than D&D's smorgaboard approach to fantasy.
The 19th-century spiritualists created all kinds of pseudo-scientific jargon for magic powers; they're the terms gamers use today: extra-sensory perception, telekinesis, etc.
For which we practicioners of fantasy games should be grateful, because the categorization of magical ability provides us alot of nice words to use in creating a systematic description of magical ability that would otherwise be difficult. However, psuedo-scientific mumbo jumbo is still mumbo jumbo.
So psychic (or psionic) flavor is really about keeping magical elements plausible in a modern, scientific setting
They are only more plausible if you accept the 19th-century spiritualists arguments that there is some scientific basis for telekinesis, telepathy, etc.
