Right. It seems that whatever is actually involved in primarily engaging in constructive developmental level 4 thinking tends to come along with a package of other things, although it's not entirely clear what that package of things is.

For example, constructive developmental level is positively correlated with leadership skill.

So that gives us some ideas of things that seem to come along with higher constructive developmental levels, but sadly the literature has primarily focused on reasoning out conclusions and done very little to test if constructive developmental level correlates with stuff, which would be useful here for figuring out what to expect at particular levels.
