What about weighting different capabilities to come to an aggregate evaluation? If we have a list of relevant capabilities, we would still be left with the question of whether the capabilities should be aggregated and, if so, what their relative weights and the formula to aggregate them will or should be. A closely related question is how different capabilities should be traded off against one another when they cannot all be realized fully. Some have argued against trade-offs on the basis that the different capabilities are incommensurable or that each capability is an absolute entitlement that never should be overridden by another entitlement or other normative consideration. For example, Nussbaum argues that the ten capabilities on her list, being incommensurable, cannot be traded off against one another (and, hence, have no relative weights), and also that the state should provide each citizen with a minimum threshold of each capability.
