Rosanna Guadagno, PhD, a social psychology researcher in Stanford’s Peace Innovation Lab and herself the mother of twin girls, believes that twins, both off and especially online, will continue to drive public interest, but that the intrigue may lessen in future generations. Today, twins still make up a relatively small number of annual births
: Of the over 3.9 million people born in 2016, only 131,723 were twins
. But as more women choose to have children later in life, they are opting for in-vitro fertilisation
, which increases the chances of having twins and multiples. The more common twinning becomes, the less unique it will seem. Nevertheless, Guadagno says, this shift is likely many years away from happening. In other words, it’s still prime time to be a twin on YouTube.
