In my last
post, ‘Can happiness be aggregated?’, I suggested that any statement about
aggregate happiness or gross national happiness (GNH) involves judgements –
explicit or implicit – about the characteristics of a good society.
I used the
example of Mary, who is flourishing at level 9, and Jane, who is just surviving at
level 1, and asked whether their combined level of flourishing is equivalent to
that of two other people who are flourishing at level 5 ( i.e. (9+1)/2). I suggested that you may feel that combining the
ratings of different individuals together should involve value judgements
rather than just arithmetic. I argued that if we introduce value weights into
the process of aggregating the flourishing of different individuals, we are
making a judgement about the extent to which the distribution of flourishing is
consistent with our views about characteristics of a good society.
I think the issues
raised by the example of Mary and Jane can be brought into sharper focus if we
consider whether aggregate flourishing increases to the same extent if Mary’s level
of flourishing rises from 9 to 10 as when Jane’s level of flourishing rises
from 1 to 2. I think most people would feel that Jane’s increased flourishing
should receive more weight than Mary’s in the assessment of aggregate
happiness. As argued above, the assignment of relative weights involves a value
judgement. Different people can be expected to have different opinions about
this matter.
The people
responsible for the GNH survey in Bhutan have taken the position that ‘beyond a
certain point, we don’t need to keep adding in higher achievements to the
quality of life mechanically’. Their methodology would not count the increase
in Mary’s level of flourishing as making any contribution to GNH on the grounds
that it is appropriate to confine attention to ‘a middle band of achievements
that contribute significantly to human wellbeing for most people’. I am not
sure whether these implicit weightings reflect a consensus of the people of
Bhutan, but in any case the weightings in the GNH index have validity as an
expression of the values of the elected government.
The way I see it, Bhutan’s GNH
index is the method that the government of Bhutan has chosen to measure
progress toward a better society.
