The science of ghost hunting

I recently received a lovely email from a pal of mine, Ian Franklin. We met when I investigated alleged ghostly phenomena at Hampton Court Palace, and so I thought that it would be a good time to re-visit the work.

As a kid, I was fascinated by ghosts and hauntings. In the 1990s, I obtained a PhD in the psychology of the paranormal from Edinburgh University and then started my own research unit at the University of Hertfordshire. One day, I received a curious letter from Hampton Court Palace.

This historic Palace has been home to many British monarchs and is now a popular tourist attraction. It also has a reputation for being haunted, with many people experiencing unusual phenomena in an area now known as ‘The Haunted Gallery’. The letter invited me to carry out an investigation (the first at a Royal Palace).

I put together a team of researchers (Caroline Watt, Paul Stevens, Emma Greening and Ciarán O’Keeffe) for a five-day investigation. It proved to be lots of fun. For instance, before we started, the Palace staged a press conference to announce my study. During a break, I stepped outside to get some fresh air and some teenagers drove past. Weirdly, one of them threw an egg at me and it smashed on my shirt, leaving a large stain. I returned to the press conference, said that the stain was actually ghostly ectoplasm and that this is going to be a tough investigation.

At the time, Ian Franklin was working as a palace warder. He was kind enough to go through the historic records and figure out where people had reported unusual phenomena in the Haunted Gallery.

Each day, I asked visitors to walk through the Gallery and write down any unusual experienced (e.g., suddenly feeling cold or sensing a presence). They were also given a floorplan of the area and asked to indicate the location of their experience. About 600 people participated. Interestingly, the experiences from those who believed in ghosts tended to take place in areas that Ian had identified from historic reports. Before the study, we had asked everyone to rate their previous knowledge about strange happenings in the Haunted Gallery, and we could see that that wasn’t a factor.

So, what was going on? We discovered that some of the experiences were caused by natural phenomena (e.g., subtle draughts), and speculated that others might be due to areas looking dark and scary. But who knows, maybe there actually are ghosts at the Palace! Importantly, the work showed that it was possible to carry out a rational and open-minded investigation into an alleged haunting, and it paved the way for my later ghost work (more about that in another blog post). Alas, little did I know that there would soon be lots of people (including those on TV) carrying out somewhat less scientific investigations into alleged ghostly phenomena!

Anyway, it was wonderful working with Ian, and the journal article about the study is here, and it also described in Paranormality.
