Now, 20th-century psychologists and sociologists were thinking about strangers, but they weren't thinking so dynamically about human relations, and they were thinking about strangers in the context of influencing practices.
Sada, psiholozi i sociolozi 20. stoljeća razmišljali su o strancima, no nisu razmišljali tako  dinamično o ljudskim odnosima, te su razmišljali o strancima u kontekstu utjecajnih praksi.
