In longterm relationships, the brain makes trust a habit

After someone betrays you, do you continue to trust the betrayer? Your answer depends on the length of the relationship, according to research by sociologist Karen Cook of Stanford University and her colleagues. The researchers found that those who have been deceived early in a relationship use regions of the brain associated with controlled, careful decision making when deciding if they should continue to trust the person who deceived them. However, those betrayed later in a relationship use areas of the brain associated with automatic, habitual decision making, increasing the likelihood of forgiveness. The study appears in the Proceedings of the National Academy of Sciences.

Cook and her team wanted to understand why some people choose to reconcile after they’ve become victims of , but others don’t. They hypothesized that if the relationship formed recently, the victim will engage in conscious, deliberate problem solving when deciding how to respond to the deceit. On the other hand, if the relationship has existed for a long time, the victim will take trustworthy behavior for granted and consider a an exception to the rule.

To test their hypothesis, the team performed an online experiment, using subjects recruited through an provider. Each subject received eight dollars and could either keep the money or give it to an unseen partner. If the subject gave the money away, its value would triple. The partner would then decide whether to keep it all or give half back to the subject.

Unbeknownst to the subject, the partner was really a computer, sometimes programmed to betray the subject early in the game and sometimes programmed to betray the subject later. Cook’s team found that after an early betrayal, the subject would be more likely to keep the money than after a late betrayal.

When the team repeated the experiment in a laboratory, with subjects hooked up to fMRI scanners, the anterior cingulate cortex, associated with conscious learning, planning and problem solving, and the lateral frontal cortex, associated with feelings of uncertainty, became more active after early betrayal. In contrast, the lateral temporal cortex, associated with habituated , became more active after late betrayal.

As with the first experiment, an early betrayal increased the likelihood of the subject holding onto the money in later rounds. Early betrayal also increased the amount of time taken to make a decision, suggesting that victims of early betrayal were putting more conscious thought into their decisions than victims of late betrayal were.

The researchers hope their study will increase understanding of why some victims of deceit continue to forgive those who deceived them.

Three years ago, I met this guy. In an instant, I knew that there was some sort of connection between us. Months later, we started dating and feel in love. We broke up, and didn’t talk for some time. Now, we are back together, stronger than ever. We tried to fight our feelings for each other, but we kept coming back and expressing out love for one another. Today, I honestly don’t know what I would do without him. I love this guy so much, and he means the world to me. He is MY interpretation of “perfection.” I love you Ross, and I always will!
