It has long been believed that there is a special relationship
between identical twins, a belief that has become the subject of
contemporary research from a variety of approaches. Research
has suggested that there are startling correspondences between
twins’ temperaments, personalities, lifestyles, and even sensitivity
to names.
In 1979, the University of Minnesota began a study of identical
twins in which twins separated for years were investigated
and subjected to medical and psychological tests. The results
of nine identical twin studies, involving over 15,000 questions,
demonstrated affinities between the subjects.
For example, unknown to each other, Jim Spring and Jim
Lewis were raised in different Ohio towns. Both married and
divorced women named Linda and chose women named Betty
as second wives. Each of the two Jims named his son James
Allan and had a favorite dog named Toy. Both twins had remarkable
similarities in medical profiles, including identical
blood pressures and sleep and heartbeat patterns. Both also
suddenly put on 10 pounds at the same time in their lives. At
the age of 18, both Jim twins suffered similar syndromes of intermittent
migraine headaches. Their drinking and smoking
habits were also identical, and both chewed their fingernails.
Another pair of identical twins, Jack and Oscar, were raised
apart with completely different backgrounds. Jack was brought
up as an American Jew by his father after his parents separated;
the mother took Oscar back to Germany (where she had been
born) where he was raised as a Catholic, later joining the Nazi
Youth party. In adult life, Jack ran a store in San Diego, while
Oscar became a factory supervisor in Germany. But both men
wore wire-rimmed eyeglasses and mustaches and two-pocket
shirts with epaulets. Both were absentminded and had other
matching idiosyncracies, such as storing rubber bands on their
Bridget and Dorothy were identical British twins who were
raised apart after being separated soon after birth, yet when
they met in 1941, each wore two bracelets on one wrist, and a
watch and bracelet on the other. Each sister also wore seven
rings. Each twin had married and had a family of a boy and a
girl. The sons had been christened Richard Andrew and Andrew
Richard, while the daughters were Karen Louise and
Catherine Louise.
Many such identical twins share IQ and psychological profiles,
as well as EEG tracings. It is not yet clear whether the coincidences
derive from some kind of psychic bonding or simply
indicate some manifestation of inheritance. It should be noted
that astrologers have investigated twins, with ambiguous results
to date, with the idea of verifying and informing astrology.
