It is flawed because there are plenty of people out there who believe in it literally! It leads some of them to do investigations with EMF boards and ouija boards and to kids hanging around churchyards at night.
Why didn't they? I think the reason is obvious: to do so would have risked causing the utmost confusion.
The difference is that the examples you quote are of theoretical agencies, originally invented by scientists themselves, which did not in fact exist. By contrast, with ghosts we are talking of a traditional concept that has two aspects - a folklore part and a very real part. By allowing the two to conflate, it causes endless confusion. If the general public used the ghost researchers definition of ghosts, they would have a much clearer idea of the difference between the two aspects. It would remove confusion, not create more.
So why do people like Jerome and yourself want to redefine the word ghost? And to redefine it in such an outlandish way as to make it literally meaningless to say, 'At first I thought I'd seen a ghost, but then I realised that is was only a trick of the light.'
As a description of a human experience, it IS meaningless. I can't help it if people say meaningless things. Apart from anything else, the phrase 'trick of the light' has no practical meaning at all. Light obeys the laws of physics, there is no trick involved.
I don't know the answer to that question, and I can only speculate. Perhaps you have some kind of residual emotional attachment to the word ghost, and you don't want to let go of it. (Religious people often behave in a similar way. They want to hang on to the word 'God', and they don't like the idea of saying, flatly, 'There is no God'. So they redefine God in a broader and vaguer way, so as to make it undeniable that God exists.)
If you give a word a more accurate definition most people, who don't really care about such things, will simply adopt it by default. If you invent a new word, only the minority who care enough will bother to adopt it. There is no sentiment involved (except perhaps passion for a badly abused subject), only pragmatism.
But, be that as it may, can't you see the scope for confusion if you insist on making your definition of 'ghost' so totally subjective, and so far from what is normally meant by the word?
You imply I have a choice when the definition is, in fact, drawn entirely from evidence. I can't change the evidence to make the word more exciting.
Just a final thought: have you a therapeutic motive? Could it be that you have a kindly, honorable (but still, in my opinion, misplaced) desire to deliver consolation to people who think they're had an experience of the supernatural? Is it that you want to be able to reassure them that, despite all the debunking which you're done, that they really and truly did (in some sense!) see a 'ghost'?
It is a definition based on scientific pragmatism, not sentiment.If someone believes they've seen the spirit of a loved one, I don't think they'd find my definition of a ghost particularly comforting at all.
