Skeptics point out the iratic results often attainted in ESP testing, looking for consitantly obtainable results. Telepathy is an art and a skill, people are not machines.The truth of the matter is that consistent results would be worrying, and indicative of some kind of 'fraud'!

Again, it has been pointed out how the performance of psychics deteriorate over a long period of time in a lab. The answer is to go to some waste ground and sprint. See how far you can sprint for, and see how many sprints you can do...not that many is it? When we use our minds in this manner we are sprinting too! And, like sprinting, performances will vary greatly from individual to individual, and from day to day with the same person.
