Trust Is Betrayed the Oxytocin Levels Go Way Down and Then You Are Fearful of Ever Trusting Again
Imagine a bare room and two players sitting face to face, about to play a game. The kickoff thespian is the "investor"; the second player is the "trustee."
At the outset of the game, both players are endowed with a set up number of points—say, 12 each—with each point equivalent to real money.

The investor can transfer whatever amount to the trustee. On the way to the trustee, the investor's transfer is tripled. Then if the investor decides to transfer eight points, the trustee receives 24 points on top of her original 12, for a total of 36.
The trustee can and so return any amount of her points back to the investor. Afterward she has made her transfer back, that'southward it. The game is over. Each player tallies her points and the coin she'll receive.
The investor's decision in this game is a decision of trust, which is why social scientists refer to this equally the "trust game" and employ it to examination trusting behavior in different situations. The more than the investor transfers to the trustee, the more she stands to profit in the end. But she must trust that the trustee will return a sufficiently large amount—at to the lowest degree every bit large as the original transfer—for the game to exist profitable for her. And what if the trustee returns nothing?
The game nicely captures the fundamental dilemma of trust in human society. The decision to trust always entails the risk of existence exploited or betrayed. However if people trust and the trust is rewarded, everyone is typically better off.
To gain the benefits that come with trust, the trusting person must always overcome her natural aversion to the risk of expose.
Conventional economical theory maintains that people volition always behave in a purely cocky-interested way. According to this worldview, it makes no sense to trust, whether in a trust game or in existent life, as any trust will be exploited.
The trustee will always go along her entire windfall for herself, so the investor would be better off non transferring whatever coin in the commencement place.
And yet when researchers like Joyce Berg and others have had people play the trust game with existent monetary stakes, they have repeatedly found that the boilerplate investor will transfer half of her initial endowment and receive similar amounts in return. Through the trust game, researchers have besides discovered a number of factors that seem to drive levels of trust. Familiarity breeds trust—players tend to trust each other more than with each new game. So does introducing punishments for untrustworthy beliefs, or fifty-fifty just reminding players of their obligations to each other.
These studies have demonstrated the force of man trust, and that humans are truly worthy of this trust from one another. They have also improved our agreement of the social factors that determine trust. But 2 of import questions remain: Is trust truly a biologically based part of man nature, and if so, what is it in the encephalon that makes humans trust each other?
Biology of trust
This question might sound circuitous, but there is a simple hypothesis about what steers the human brain to trust another homo: a hormone chosen oxytocin.
Oxytocin is produced in the brain's hypothalamus and stored in the posterior pituitary gland. We know that it helps smooth muscle contractions in childbirth and in breastfeeding mothers. But recently we've discovered that its applications go beyond the maternal. It turns out that oxytocin also reduces social anxiety and helps people meet and bond with each other. A man and adult female involved in the mating trip the light fantastic are releasing oxytocin; so are friends having a good time at dinner.
Forming relationships like these involves trust, just is there a direct connection between trust and oxytocin?
To notice out, my colleagues and I conducted an experiment in which participants took either oxytocin or a placebo. Fifty minutes afterwards, participants played the trust game against four dissimilar anonymous partners. They played with existent money, with each point worth nearly one-half a Swiss franc.
The results revealed that oxytocin does indeed seem to grease the wheels of trust. Of the 29 investors who had taken oxytocin, 45 percent transferred the maximum amount of 12 points in each interaction. Past contrast, only 21 percent of the placebo-group investors did so. The average transfer fabricated by the oxytocin-group investors was 9.6 points, compared with 8.i points past the placebo-group investors.
Interestingly, the investors' expectations nigh the back-transfer from the trustee did not differ between the oxytocin and placebo recipients. Oxytocin increased the participants' willingness to trust others, merely information technology did not make them more optimistic nearly another person'south trustworthiness.
The results indicate that oxytocin does indeed aid humans overcome distrust. But does oxytocin really increase trust, or does it only brand us experience and then skillful that we lose our aversion to gamble and betrayal?
To effigy that one out, we conducted a second experiment, in which investors faced the aforementioned choices as in the trust game. The investors in this experiment were over again in a risky situation, only this fourth dimension in that location was no human beingness on the other side of the tabular array; instead, investors faced a computer that generated random numbers of points. Everything else in the "risk experiment" was identical to the trust experiment.
The upshot? Investors who'd received oxytocin behaved no differently than those in the placebo groups. We therefore concluded that the effect of oxytocin is, indeed, specific to trusting other people and the willingness to take risks in social situations. Oxytocin does not affect human being attitudes toward risk and uncertainty in situations where there are no other human beings involved.
In short, trust is very much a biologically-based part of the man status. It is, in fact, one of the distinguishing features of the human species. An element of trust characterizes well-nigh all human social interactions. When trust is absent, we are, in a sense, dehumanized.
Applied trust
The discovery that oxytocin increases trust in humans is probable to accept important clinical applications for patients suffering from mental disorders like social phobia or autism. Social phobia ranks as the tertiary most common mental wellness disorder afterward depression and alcoholism; sufferers are severely impaired during social interactions, and are oft unable to show fifty-fifty basic forms of trust toward others.
Given the results of our trust studies, the administration of oxytocin, in combination with behavioral therapy, might yield positive furnishings for the treatment of these patients, specially in light of its relaxing furnishings in social situations.
At the aforementioned time, still, the results from these experiments heighten fears of abuse. Some might suppose that unscrupulous employers or insurance companies could use oxytocin to induce trusting behavior in their employees or clients. Dishonest auto salesmen might spray customers with the hormone before steering them toward a lemon.
Fortunately, near of these fears are baseless: The undercover assistants of a substantial dose of oxytocin—for instance, through air conditioning, food, or drinks—is technically impossible. Of course, i could always forcefulness the spray upward another'southward nose. Just it'southward safe to say that this would alert recipients enough to override any glow they might get from the oxytocin.
Information technology is more likely that advertisers might notice ways to cleverly design stimuli to trigger the release of oxytocin in consumers through, for example, strategically placed smiling faces or warm handshakes, or perhaps fifty-fifty by measuring people's oxytocin levels in focus groups. All this might make these consumers more than inclined to trust the claims made past the advertisers. Of course, advertisers (and nigh socially-intelligent humans) take always intuitively understood ways to dispense perception and build trust; this simply gives them one more tool for their kit. However, knowledge can cutting both means: Past better understanding the underlying biological mechanisms of these stimuli, research into oxytocin could be even more useful for protecting consumers from the manipulative strategies of marketing departments.
To some people, these findings almost oxytocin might raise another concern: that trust is not subject to rational control—that it'southward "all hormones." This seems to stand in stark contrast to the traditional idea of trust existence the outcome of a cognitive, rational process.
In my view, trust is both, just like other human social behaviors. We cannot deny that many of our decisions are governed by cognitive processes, which in the example of trust take into account the bachelor data nigh the trustee'south motivation, the likelihood of a repeated interaction, and so on.
Nevertheless, research like this shows that our behavior is also influenced by a large number of very circuitous, withal identifiable, biological processes. Future enquiry should help us sympathise how cognitive and biological processes collaborate in shaping our decisions nigh whom to trust.
Simply there's no denying the of import function trust plays in cooperative behaviors, or that humans take a securely rooted ability to trust. It's upwards to us to earn that trust from ane some other.
