Ganzfeld telepathy experiments
A long-running test of telepathy: a 'receiver' in mild sensory deprivation tries to pick which of four images a 'sender' is concentrating on.
1974 CE · 40.71, -74.00 · status: disputed
The account
Chance is 25%, and pooled analyses by parapsychologists report hit rates of around 30–32%. It remains the most-debated experiment in psi research.
The sceptical view
Meta-analyses are contested: results shrink with tighter controls, file-drawer effects and flexible analysis. A major 1999 meta-analysis found no effect.
