Why does types of relationships fail?

The most common reason types of relationships fails: Treating all relationships as the same type — usually causal. When every connection in your mental model is "A causes B," you lose the ability to distinguish influence from structure, sequence from dependency, and correlation from mechanism. The result is a flat map where everything seems to cause everything else, which is the same as having no map at all.

The fix: Choose a belief you hold about how two things in your life are connected — for example, 'reading before bed helps me sleep' or 'team standups improve collaboration.' Write down the connection, then classify it: is it causal, associative, temporal, hierarchical, compositional, or something else? Now ask: what evidence would distinguish between the type you chose and an alternative type? If you labeled it causal but cannot describe a mechanism, you may be looking at an association dressed up as causation.

The underlying principle is straightforward: Relationships can be causal, temporal, sequential, hierarchical, associative, and more. Naming the type of a relationship determines what reasoning you can perform across it.
