That does not mean researchers proved that correcting a perception gap equalizes happiness more than closing an income gap. This is a comparison of regression coefficients, not a promise that telling someone their neighbor is kind will raise life satisfaction by 0.75 points. Safer, better-governed places may produce both trust and life satisfaction. People who judged others to be fair and helpful appeared to lose less life satisfaction in association with unemployment, poor health, discrimination and unsafe streets. Likewise, “income gap” and “happiness gap” are different quantities.
