Comparisons are most often made between people who resemble one another ​ — who are of the same sex, of a similar age, and at a similar social level and who know one another.
Kõige rohkem võrdlevad end omavahel sarnased inimesed – samast soost, samavanused ja samal ühiskondlikul positsioonil olevad ning need, kes üksteist hästi tunnevad.
