> So basically it has a negligible impact on happiness even if this analysis is true. You are wrong. The paper goes on to say, in the very next sentence, that 3% is "approximately one half the absolute size of the marriage effect on life satisfaction, or approximately one quarter of the absolute size of the effect of being unemployed", thus (while smaller), it's the same order of magnitude. Presumably you do not consider the impact of marriage or unemployment "basically negligible"? > It is really, really hard to actually change people's opinions with advertising. That may be as it may, but that is not what the paper is talking about.
