Procedural judgments of fairness concern the distribution of goods and resources, while substantive judgments of fairness concern the rules and procedures used to allocate those resources.

There is no distinction between substantive and procedural judgments of fairness.

Substantive judgments of fairness are based on efficiency or economic value generation, while procedural judgments of fairness are based on equality of treatment in rules.

Substantive judgments of fairness are usually based on factors such as income, happiness, and wealth, while procedural judgments of fairness are usually based on aspects such as equal opportunities, deservingness, voluntary choices and actions.

Substantive judgments of fairness concern the distribution of goods and resources, while procedural judgments of fairness concern the rules and procedures used to allocate those resources.
