If the electrodes are attached correctly, your test subject should begin to ‘receive’ your mental waves and, subsequently, begin to provide approximations of the simple graphics represented on your card. This can be exhilarating for the test subject, so be careful to monitor their excitement levels. Remind them that this is a scientific experiment, for Christ’s sake, not ‘Give Us A Clue’, by occasionally administering a small electrical shock, somewhere between 1,000 and 1,500 volts. More than this will cause involuntary defecation, which can be unpleasant for the audience.
Currents of above 2,700 volts are often fatal, so remember to use them sparingly.
Do not be disheartened if the answers are slow to come or, indeed, if they are initially wrong. Most importantly, do not blame yourself. It is the test subject’s fault, as they are either too stupid or selfish to receive your signals. Fact is, they just don’t get you, they never have.
Be patient, let them show themselves up for what they are, then, once you are sure that the experiment has gone irrevocably pear shaped, give them 3,000 volts and then buy the attractive psychic lady a pint while they’re mopping up the mess.
