Szondi concluded that genetic traits confer needs and tendencies that shape decision making. "Genetic tendencies can be decoded by constructing genealogies, indicating recurrent patterns of marriage, friendship, and vocational choices in relation to types of illness and modes of death. Destiny comprises all of the hereditary tendencies in the familial unconscious which are expressed primarily through marriage and vocational selections." Basically, the needs and tendencies in which humans exhibit will guide similar genes to one another.
