However, I also agree that Venn diagrams are a poor way to do things, even with 3 variables. Truth tables or 2x2x ... x2 tables are much easier to understand. Occasionally, tree diagrams may be more instructive; they are a way of pulling apart truth tables to get at the causal structure. -- This address is for information only.
