Best when players are already well acquainted.
Attach velcro pads to two fingers of one player and connect to the lie detector. You don't feel anything at all. When the instrument has calibrated, you're ready to start.
Players are asked questions. A series of lights on the machine indicate their emotional response.
The game includes a pack of cards with words and phrases which can be useful. There is also an audio cassette for special effects.
1 x velcro 2 finger contacts and lead with jack plug
1 x pack of cards
1 x audio cassette containing special effects
1 x rules leaflet within the audio cassette case
Open Secrets is not a lie detector per se. Nor in fact is the polygraph. It measures emotional response, in particular, embarrassment, guilt, humour and sexual arousal. The cards and cassette will help you use Open Secrets but it's much more fun making up your own stimuli.
Generally Open Secrets works best when the stimuli are close to the margins of what is socially acceptable. It is up to the questioner to decide how far to go, bearing in mind it may be their turn next.
