About this show

Would you take a lie-detector test in a room full of strangers? Watch on or be interrogated, as we seek out truth in a world of fake news and alternative facts. Using real biometric sensors and live voting systems, Truthmachine, is the multi award-winning social experiment from renowned techno-troublemakers Counterpilot. The polygraph machine used to be regarded as a legal instrument, but today we think we can cheat it... Let’s see if your heart-rate can lie as effectively as our leaders can. ‘No one else is making work quite like this’ (Age, Melbourne).

  • Truthmachine is slick, unusual and technically accomplished, and its clinical atmosphere is extremely well realised.

    — North West End UK (3 out of 5 stars)

  • genuinely interesting

    — Three Weeks (3 out of 5 stars)

  • This is a really well presented audio, interactive drama using jury selection style machines, lie detector and a slightly disorientating sound scape.
