The Evidence Chamber

A murder has been committed. There’s a suspect but the evidence doesn’t paint a clear picture.

There’s been a murder. The police have a suspect but the evidence doesn’t paint a clear picture. In an online jury deliberation room, you watch the testimonies, scrutinise the evidence, discuss with your fellow jurors – and reach your verdict.

The decision you make will change someone’s life: what will you decide?

If you’re a fan of crime fiction or true crime, this is the show for you. The Evidence Chamber is the second courtroom show from the team behind The Justice Syndicate (4* Irish Times, Lumen Prize longlist).

The Evidence Chamber is a collaboration with the Leverhulme Research Centre for Forensic Science at the University of Dundee.

What happens during The Evidence Chamber?

In this experience you will:

  • be in an online jury deliberation room, with players you don’t know
  • watch video testimonies and look at evidence documents from a fictional case
  • discuss your opinions on the verdict with other players, via video chat

You will be guided 70% of the time; 30% of the time, during discussions, the group will self regulate.

How long does it take?

Depending on how long your jury takes to reach a decision, the first part of the experience is around 90 minutes. This is followed by a 20 minute debrief where you can compare your experience with that of other juries and learn more about the research behind the show. Past players have told us that the debrief is a really important part of the experience. So the whole show is max 2 hours.

Do I have to be really good with technology?

No. The whole experience is contained within one browser window. There is a tutorial and there will always be a (human) moderator on hand in case you have any problems.

I don’t want to be on the jury. Can I just watch?

No. Real juries don’t have spectators, because it might change how people behave or what they say. The same applies here.

What if another juror says something that upsets or offends me?

We are committed to this being an accountable space.  We ask everyone to read and subscribe to our Safer Spaces code before playing. If something that upset you happens during the game and you don’t want to deal with it yourself, you can message the moderator, who will take action.
