Redundant Pre-Stimulus Response

Receiving Accurate Messages from the Future  

General Information

 James Spottiswoode invites you to participate in a novel precognition experiment.  This experiment will test whether it is possible to send small amounts of information backwards in time with a high accuracy.  The experiment is based on an automatic response in our physiology.  It has been known for a hundred years that when we are alarmed or surprised we sweat slightly and this can be measured by monitoring the electrical resistance of our skin.  Recently it has been discovered that a similar effect occurs just before the surprising event – that is our skin conductance shows that we react about 3 seconds in advance of stimulation. 

With medically approved equipment, we monitor the properties of your skin at your fingertips. Our skin sometimes reflects our emotional state. That is, if you are a little nervous or you are suddenly surprised, your hands become a bit damp. Our sensitive equipment can sense that change long before it is obvious to you.

This experiment is very important because it is showing us that our nervous system can correctly anticipate the startling sound—even before the system has randomly decided whether to present the sound. This appears to be physiological evidence of precognition—peeking slightly into the future.

If this experiment is successful it will be an important demonstration of a backwards-in-time, or retrocausal, communication channel.  A demonstration of this effect poses a major challenge to existing physics and opens the way for a number of interesting experiments in causality

What is Involved in Participating

During the experiment you will be sitting in an auditorium for approximately 20 minutes.  Two electrodes will be attached to your fingertips which are connected to a medically certified Skin Conductance measuring system.  During this period you will hear approximately 10 bursts of white noise, each lasting one second.  These sounds are designed to be quite loud (about 95 dB), which is not painful, but rather startling. We shall ask everyone to sit quietly through the 20 minute session while concentrating on anticipating when the sounds will occur.


Your individual results will be mailed to you after the experiment.  We will also let all participants know how the whole group performed and how much information we were able to transmit backwards in time.

How To Participate

To save time on the day of  the experiment and to ensure that we can get your results to you in a timely fashion, we would ask you to register your intent to participate online before you arrive.  The link below will take you to a form where you can enter your name, age, gender and contact information.  You will then be given a unique registration ID number.  Please make sure that you bring this number with you to the experiment.  The information you give us in registering will be treated in complete confidence and will not be passed on to any third parties, but used only for this experiment.

Register Here Please

We are hoping to have 100 participants in each experiment.  So we encourage you to join us and to bring your friends!
