6. Sibling Position
Bowen stressed sibling order, believing that each child had a place in the family hierarchy, and thus was
more or less likely to fit some projections. The oldest sibling was more likely to be seen as overly
responsible and mature, and the youngest as overly irresponsible and immature for example.
Think of the oldest sibling who grows up and partners with a person who was also an oldest sibling.
They may be drawn to each other because both believe the other is mature and responsible.
Alternately, an oldest sibling might have a relationship with someone who was a youngest sibling. When
one partner behaves a certain way, the other might think "This is exactly how my older/younger sibling used
to act."
Bowen theory incorporates the research of psychologist Walter Toman as a foundation for its concept of
sibling position. Bowen observed the impact of sibling position on development and behaviour in his family
research. However, he found Toman's work so thorough and consistent with his ideas that he incorporated it
into his theory. The basic idea is that people who grow up in the same sibling position predictably have
important common characteristics. For example, oldest children tend to gravitate to leadership positions and
youngest children often prefer to be followers. The characteristics of one position are not "better" than those
of another position, but are complementary. For example, a boss who is an oldest child may work unusually
well with a first assistant who is a youngest child. Youngest children may like to be in charge, but their
leadership style typically differs from an oldest's style.
Toman's research showed that spouses' sibling positions affect the chance of their divorcing. For example, if
an older brother of a younger sister marries a younger sister of an older brother, less chance of a divorce
exists than if an older brother of a brother marries an older sister of a sister. The sibling or rank positions are
complementary in the first case and each spouse is familiar with living with someone of the opposite sex. In
the second case, however, the rank positions are not complementary and neither spouse grew up with a
member of the opposite sex. An older brother of a brother and an older sister of a sister are prone to battle
over who is in charge; two youngest children are prone to struggle over who gets to lean on whom.
People in the same sibling position, of course, exhibit marked differences in functioning. The concept of
differentiation can explain some of the differences. For example, rather than being comfortable with
responsibility and leadership, an oldest child who is anxiously focused on may grow up to be markedly
indecisive and highly reactive to expectations. Consequently, his younger brother may become a "functional
oldest," filling a void in the family system. He is the chronologically younger child, but develops more
characteristics of a
