It's from a study called the National Accounts of Well-Being. According to Easton, the study
tries to measure trust and belonging by comparing answers to questions such as these:
• Generally speaking, would you say that most people can be trusted, or that you can't be too careful in dealing with people?
• Do you think that most people would try to take advantage of you if they got the chance, or would they try to be fair?
• Would you say that most of the time people try to be helpful or that they are mostly looking out for themselves?
As you can see, young people in Great Britain and Bulgaria are the least trustworthy. The most trusting appear to be in Hungary and Norway. Strangely, there don't seem to be any sort of patterns to the geographical distribution of trust whatsoever. Scandinavia - so often a uniform block of strong social health indicators - ranges from the very trusting Norwegians to the fairly suspicious Finns. The old Warsaw Pact countries include one the trustingest (Hungary) and one of the least trusting (Bulgaria). Catholic or Protestant countries? Ethnically homogeneous or plural society? There seem to be no strong correlations.
However, the study also rates overall well-being, which combines ratings of social well-being like the one depicted above with ratings of individual well-being, such as "positive feelings," "vitality," "self-esteem," a sense of meaning and purpose, etc. And here some clearer patterns begin to emerge. And here, irritatingly, Scandinavia's dominance of positive social indicators once more asserts itself: Norway, Sweden, Finland and Denmark, plus the might-as-well-be-Scandinavian Netherlands, all score near the top; but so do the Alpine countries of Switzerland and Austria. (I tell you, mountains are good for the soul!) And - also true to form - the old Eastern Bloc countries bring up the social health rear, with Ukraine putting in a particularly weak showing.
One final note: the study also rates "optimism." And who comes in dead last in that category? France. Shocking, I know.
