“Researchers at the Princeton Engineering Anomalies Research program, or Pear, have been attempting to measure the effect of human consciousness on machines since 1979. Using random event generators — computers that spew random output — they have participants focus their intent on controlling the machines’ output. Out of several million trials, they’ve detected small but “statistically significant” signs that minds may be able to interact with machines. However, researchers are careful not to claim that minds cause an effect or that they know the nature of the communication.”
