A new study has it that although the famed "love hormone" Oxytocin (OT) fosters trust in people, it doesn't make them gullible.
Increased levels of OT have been associated with greater caring, generosity, and trust.
But researchers wanted to find out if OT increases people's trust in just anybody or if it act more selectively.
Psychological scientist MoIra Mikolajczak from the Universite catholique de Louvain (Belgium) and her colleagues investigated just how trusting OT can make us.
In this experiment, volunteers received either a placebo or OT nasal spray.
Then, they played a trust game in which they received a certain amount of money, which they could share with a partner (any amount shared with the partner would then triple).
The partner then decides what to do the money-they can keep it all for themselves or split the amount with the giver.
If the volunteer is trusting, they will share more money with their partner (in the hopes of having some of it returned to them) than volunteers who are not as trusting.
The participants played the trust game against a computer and virtual partners (which were supposedly in another room), some of whom appeared reliable (they seemed likely to share the money with the participants) and some of whom appeared unreliable (they seemed likely to keep the money for themselves).
The results, showed that volunteers who received the OT nasal spray were more trusting of the computer and the reliable partners-that is, they offered more money to the computer and the reliable partner than did volunteers who received the placebo nasal spray.
