I heard it too. Unfortunately, I didn't think much of it at all! Disappointing.
They interviewed two experimentors. One had put together this simulated room, and got various people to spend fifty minutes in it. Sometimes the experimentors transmitted low-level sound and electro-magnetic charges (or whatever they were) into it, and sometimes they didn't. They asked people to tell them when they experienced sensations, such as feeling dizzy, or feeling as if there was a presence there. Totally predictably, the interviewee said some people experienced weird sensations when nothing was happening at all. The scientist being interviewed said they then tested the temporal lobe activity (or something of that nature) of both those who'd felt sensations when there was nothing going on and those who hadn't. He said those who had felt something had higher activity, and he said that was known to be correlated with suggestibility.
He didn't say how well correlated.
Nor did he say whether any of the people who experienced something when there Was something there said they could have mistaken it for a ghost if they didn't know better. For instance, he said one sensation he told people they might feel was dizziness. His simulated room was just a round bare space. If some of them had got dizzy, it might have been from pacing around and around in it for the want of anything else to do!
The scientist said that a high percentage of people did feel as if there was another presence in the room with them sometimes, but didn't say how many of those were the "suggestible" ones.
So he was rather vague as to whether his experiment had been worthwhile, and there didn't seem to be too much point interviewing him. The sensible thing for him to have done might have been to take the suggestible people out of the experiment and to have done it again with the others, and asked them whether they might have assumed there could be a ghost there if they didn't know what was causing the sensations.
The second interview totally missed the point, in my opinion. The interviewee said it had been discovered that a bed in a castle reputed to be haunted had a particularly strange magnetic field about it. He totally neglected to mention whether, or what sensations people who'd actually slept in it had reported, and whether they had taken those in particular to be evidence of ghosts in the vicinity. He said there were other reasons the castle may have got its reputation for being haunted, such as things about its general atmosphere, like portraits of medieval characters looking out. Thus, the relevance of the magnetic oddity about the bed was left totally open to question, which, since it was supposedly the reason for the interview, rendered the interview rather pointless. The scientist did say there was a "complex" feel around the bed, but didn't attempt to explain himself any further whatsoever.
The interviewer only had a short time to ask the questions, so obviously neither experiment could be discussed in much depth at all. But still, they could have utilised the time better by asking better questions, although it wasn't entirely their fault. They did ask a question about one experiment, and the scientist started going on about how people in the experiment had rolled around in the bed creating all kinds of odd magnetic wave forms on his equipment. As if that was the point!

He didn't say a word about whether they actually felt any strange sensations.
I think I could have done a better job of interviewing him.
Still, the interviewer did do a good interview with someone before that, with someone who did some experiments and found that people who witness rudeness tend to get too angry and distracted to be creative.
