> “I always thought I picked up my nervous habits from my father – like fidgeting with other people’s rubber bands and pads and paper clips—until I saw [Oskar],” Yufe said in The Times. “He’s the same way.”
They were separated at 6 months, is it possible they picked up this trait by observing their father at such an early age?
> it's something both their parents transmitted culturally/behaviorally because they themselves converged by living together
I very much agree and I think there is even more here:
The people in charge of their education (mother, father) weren't "drawn independently", they are two people that chose and love eachother (at least for some time).
People who marry each other tend to come from similar cultural background, or they can share some interests. All of this can then be transmitted to their respective kids.
After all Jack & Oskar's parents probably both liked white jackets before they even met.
'In early 1979, Yufe’s then-wife, Ona, showed him a magazine article
about the “Jim Twins,” a pair of long-separated Ohio twins who were
each named Jim by their respective adoptive parents. Like Yufe and his
brother, Jim Springer and Jim Lewis found each other as adults and were
astounded by the parallels in their lives, including similar jobs in
law enforcement and ex-wives with the same first name.
The two Jims had become the first subjects of the Minnesota twins
study. Yufe was intrigued and thought he and Oskar should also
participate.
...
The researchers jumped at the chance and invited them to Minnesota for a
week. Yufe and Stohr became the seventh set of twins to enter the study.'
The Study was instantiated when a potentially unusual situation occurred. People were then allowed to join the study themselves, after hearing about strange twin coincidences.
