Note that while most types of capability analysis require interpersonal comparisons, one could also use the capability approach to evaluate the well-being or well-being freedom of one person at one point in time (e.g., evaluate her situation against a capability-yardstick), or to evaluate the changes in her well-being or well-being freedom over time. The capability approach could thus also be used by a single individual in her deliberate decision-making or evaluation processes, but these types of uses of the capability approach are much less prevalent in the philosophical literature, let alone in the social sciences.
