Yupp. That one. Maybe the OP could change the title to include 'irrationality' (or add a tag) to stay in the original spirit.
My understanding is that this is explicitly meant not to be quite the same thing as the Irrationality Game. Specifically, in the IG the idea is to find things you think are more likely to be true than the LW consensus reckons them; here (I think) the idea is to find things you think are actually likely to be true despite the LW consensus.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
