Researchers have developed a method to understand the partial order of causal structures with latent variables based on observational dominance. This involves determining which causal structures can produce the same set of distributions over visible variables. The study provides a complete characterization for three visible variables and a partial one for four, suggesting that constraints beyond conditional independence are crucial for distinguishing between causal structures.
