Ganzfeld experiments involve a ‘sender’ trying to project images from a video clip to a ‘receiver’ who is incubated, blindfolded, in a sound-proof room. The ‘receiver’ reports the images they believe they are receiving to a researcher who notes them down. Crucially, the next stage involves the researcher reviewing these images with the ‘receiver’, before the ‘receiver’ attempts to identify the video clip seen by the ‘sender’ from among three decoys.
Robin Wooffitt analysed recordings taken from ganzfeld experiments held at the famous Koestler Parapsychology Unit in Edinburgh during the mid 1990s. He found that as the researchers reviewed the images reported by the ‘receivers’, they tended to respond in two distinct ways.
After a clarification by the ‘receiver’, researchers sometimes said “okay” and moved decisively onto the next item. Other times, however, they said “mm hm” with an inquiring tone. After hearing this, ‘receivers’ typically tried to expand on their description, and as they did so, often ended up casting doubt on the clarity of their own imagery.
Forskeren bakom, Robin Wooffitt ser ut til å tolke svakheten som å ha medført mer usikkerhet og færre treff når skeptiske forskere har stått bak eksperimentet.
