Psychology edition
Fewer positions and more cards about study design, including experiments, scales, diaries and the main families of statistics. The round-table would ask whether the design can support a causal claim.
The design cards would matter more than in the arts edition, because in psychology the argument is usually about what a study design allows you to conclude.
Central card: Position, and the kind of claim. The game is played the same way in every edition. Everyone studies one shared object, each turn is to draw one card and then play one or discard one, and the game ends with a round-table discussion of each research question.
