Random number generators have many advantages over earlier research such as using tossed coins or dice. In the RNG experiment, great flexibility is combined with careful scientific control and a high rate of data acquisition.
Here is an good link refuted common criticism thrown at parapsychological experiments. It also discusses the hundreds of experiments that support psi, and also gives detail information on the experiments being repeated.
