Twins, both fraternal and identical, have fascinated the world for millennia. They are often very close, and share not only genes but home environments, friends, clothes and, of course, secrets. However many identical twins — perhaps as many as one in five — also claim to share something more mysterious: a special psychic connection.
About one out of every 30 babies born in the United States is a twin, and identical twins are especially interesting because they have the same genes and are alike in many ways. Brothers and sisters can be close, but some twins claim to know what the other is thinking or feeling. It’s an intriguing idea, but what’s the truth behind it — coincidence, psychic powers, or something else?
Twins often finish each other’s sentences and think the same thoughts, but that has more to do with shared experiences than any psychic telepathy. This sort of psychological connection isn’t necessarily mysterious: any two people who know each other very well and who have shared many common experiences — including non-twin siblings, old married couples, and even best friends — may complete each other’s sentences and laugh at inside jokes that leave outsiders baffled.
