First They Separated the Twins...
By Bryan Caplan
I staunchly oppose putting twins in separate classrooms when they prefer to be together. As I explained before:
Sure, if you separate twins, they’ll make more friends. But that
hardly means you’re doing them a favor. The reason why twins put less
effort into making new friends is that they’ve already got a better
friend than most of us will ever have. For twins, the marginal benefit
of trying to making new friends unusually small – and cliquishness is
their optimal response.
The classic best-friend bond — the two special pals who share secrets
and exploits, who gravitate to each other on the playground and who
head out the door together every day after school — signals potential
trouble for school officials intent on discouraging anything that hints
of exclusivity, in part because of concerns about cliques and bullying.
Frankly and fortunately, I doubt the war on best friendship will get very far. But this is indeed the slippery slope down which the main arguments for twin separation lead.
