For large enough X, if X% of the population were to be more kind and tolerant of each other, then that would "produce measurable improvements in the quality of life for the whole population". I'm sure there's some way to quantify this with graph theory (something something random graph, social network dynamics, threshold effect), but while it's technically true, it's not really something worth naming after yourself. And intuitively I suspect the X needed is a bit higher.
