Contract law governs economic relations far better than professional or personal ones

Evidence

These devices have no match in professional contexts, although control of professional behavior may be changing toward sterner regulation. Similarly, economic relations between individuals are relatively well governed by institutional controls. Other relations are typically much less well governed. Some areas are coming under increasing institutional oversight, as are some gender relations and some intrafamilial relations. Still, contract law, for all its difficulties, seems almost like an ideal type in comparison with many other institutional controls over individual commitments. — Russell Hardin, Trust and Trustworthiness, 258

• XREF: The uneven reach of institutional control over different relationship types maps onto the reader’s question of which relationships survive blindness — personal/intrafamilial relations lack institutional backing and degrade first.
