In a low-synergy community such as the one I was born into people find trusting difficult. Hence they tend to cleave to family bonds and kin relationships with more neediness than would otherwise be the case. Their mistrust of strangers is greater than in communities which enjoy higher levels of synergy.
Low synergy is bad for relationships and puts undue stress on them. They are unable to flourish as they might and tend to remain underdeveloped. They are maintained more for instrumentality than for quality of connection.
If you live in an environment like that sooner or later you'll be pulled into its needy dynamic. You are required to be like the rest and make similar demands. It is not a conscious thing necessarily, simply part of the fabric of association. They think this is how it has to be with no sense that things might be done differently. Unfortunately their understanding of love is reduced to a form of dependency.
Of course what I am saying here could be said of all communities. It is intrinsic to tribalism. But it exists in varying degree and to whatever degree it does has an import to mental health. Too much drawing on relationships for subsistence and base purposes corrupts their potential. Such corruption is a defining aspect of low synergy.
