In the 1970s, Karlis Osis conducted many OBE experiments with the psychic Alex Tanous. In one series of these experiments, he was asked whilst in an OBE state whether he could identify coloured targets that were placed in remote locations. Osis reported that there were 114 hits in 197 trials. However, the controls for the experiments have been criticized and, according to Susan Blackmore, the final result was not particularly significant since 108 hits would have been expected by chance alone. Blackmore noted that the results provide "no evidence for accurate perception in the OBE".
