My starting point for this post is take it as given that everyone agrees that for public policy purposes it is appropriate to view happiness in terms of individual flourishing. My reasons for this view have been presented in the draft of chapter 2 of the book that I have been writing.
I doubt whether it is possible to obtain an accurate measure of the extent to which each individual in the community is flourishing because some of the subjective information involved is probably not accessible to people conducting surveys. But let us assume that we have a measure that is good enough to compare the extent to which different people are flourishing in terms of a rating scale from 1 to 10, with a rating of 1 indicating that the individual is just surviving and a rating of 10 indicating that the individual is fully flourishing.
The measurement system that I am assuming would enable us to determine the percentage of people at different levels of flourishing within a particular community. If other communities adopted the same measurement system we could make observations about the percentage of people who are flourishing in different communities. It might be possible to say, for example, that 50 per cent of the population in community A are flourishing at a moderate level (with a rating of 7 or above) whereas the corresponding percentage in community B is only 40 per cent. There could be considerable interest in such observations, particularly if they enabled comparisons to be made between countries and over time.
Would such a measurement system enable us to say that the aggregate or average level of flourishing is higher in one country than another? I don't think so. For example if you are told that 50% of the population is flourishing in country A and 40% is flourishing in country B, that doesn’t necessarily mean that the average level of flourishing is higher in A than B. It is possible that 20% are struggling for survival in country A while only 5% are struggling for survival in country B. The average (mean) calculated from the percentages flourishing at each level might indicate that the level of flourishing is higher in B than in A. In this instance, is the mean a better measure of the 'average' than the median?
There is also a more fundamental problem. Let us assume that Mary is flourishing at level 9 and Jane is just surviving at level 1. Is their combined level of flourishing equivalent to that of two other people who are flourishing at level 5 (i.e. (9+1)/2)? I don’t think so. It seems to me that, other things equal, it is preferable to have two people flourishing at level 5 than to have one person at level 1 and the other at level 9. But that judgment reflects my own values and is not related to the preferences of the people most directly concerned? We should ask Mary and Jane what they think. But their views might differ. Perhaps we could ask a random sample of the population what they think, or conduct experiments to find out what choices most people might make behind a veil of ignorance.
The point I am getting to is that even if you can conceive of ratings corresponding to different levels of flourishing, you may have good reasons to feel that combining the ratings of different individuals together should involve value judgments rather than just arithmetic. You may not be comfortable in thinking of the combined level of flourishing of Mary and Jane as though these individuals are just metric stations.
However, if we introduce value weights into the process of aggregating the flourishing of different individuals, are we not then making a judgment about the extent to which the distribution of flourishing is consistent with our views about the characteristics of a good society? It seems to me that any statement about aggregate happiness or gross national happiness involves judgments – explicit or implicit – about the characteristics of a good society.
So, why not ask directly whether society A is better than B, rather than asking whether aggregate happiness is greater in A than B? This would mean attempting to achieve consensus on the characteristics of a good society. I presented some thoughts about this in a post a couple of years ago.
