On Collective Debate users take a test of their morality, then debate an artificial agent on a controversial claim. Users indicate how much they agree with the claim, then they exchange arguments with the agent. After the debate, users re-evaluate their position. The agent is trained to make arguments that nudge the user to become more moderate.
Sometimes you and your friends, partners, or relatives get into debates. Sometimes, you can't agree so we like to hear other people's opinions on our thoughts. Post a question, your take, then invite the one person you want to debate or argue with. They put in their take on the question. The public votes on which side they think is right.
