Well, let's take a look at the options you've offered us:
First, for the sake of argument I'm assuming that "confirmed by science" actually means a valid scientific test, as opposed to a con man managing once again to do close-up magic in front of an inattentive scientist.
Sheer joy and excitement
No. It would be very interesting, would open up lots of new possibilities. But this is a little strong.
Shock!
Also too strong. Is "somewhat surprised" or "pleasantly surprised" an option? No, I see it isn't.
No real surprise, earlier research indicated it
So if I'm not ecstatic, my only option is to believe in previous faulty research? But the earlier research was faulty, I don't think it indicated a positive result.
I still wouldn’t believe it, it would be some error or organized fraud
So if I'm not ecstatic, then I have to be pathologically disbelieving? Since we're accepting as a premise that the research was sound, why is this the only option to "ecstatic"?
Feelings of guilt for misguiding others
No, definitely not, since the earlier research was flawed. There was no misguiding or misinforming. Statements about failure to demonstrate psi have been justified.
Concern over organized skeptic movement possible collapse
That's just silly.
Continue with skepticism towards any link made from psi to ghosts, souls or life after death
If none of this was part of the experiment, why should I suddenly decide all woo-woo theories were correct based on... what exactly? What are we hypothesizing to have occurred in this experiment?
Too little information to say what I would or wouldn't accept as a conclusion. I can safely say that I wouldn't suddenly say "everything I disbelieved in, I now believe in." That would be silly. So I guess this is the closest to a response I'd agree with.
Save face … ‘It’s a victory for the scientific method, I have been discussing those matters for some time’
There seems to be some dishonesty or spin-doctoring implied here. Are we or aren't we saying that this hypothetical experiment represents good science? If it does, then I'd have to accept it. What is slimy about that?
I don’t like this poll
Well, I don't. It seems to be limited in the options and full of editorial opinion on most of the choices that come closest to honestly reasoned.
I refuse to vote
Ah, at last I find a position I can agree with.
