In human chemistry, the term hate signifies an intense aversion to someone or something, described quantum electromagnetically as an effect or force of repulsion.  In human chemical bonds, "hate" or the quantum stability effect mediated by the psychological effect of the phenomenon is a necessary component in bond stability, generally quantified in a 5-to-1 ratio (Gottman stability ratio) of love-to-hate or attraction-to-repulsion in stable long-term marriage bonds. 
The range of attraction (like) or repulsion (dislike) effects mediated by "force exchanges" in human life, e.g. a smile or a frown, exists as a gradient on a range of extreme repulsion to extreme attraction:
Situational Bond Type Scale
The numbers shown, represent a gradient on a nine-point situational bond type (SBT) scale, numbers which can be used to quantify the "set" of over-lapping attraction and repulsion forces existing in any given human bond.
