Deception is an integral part of life. Unseemly as it may sound, everybody lies\u2014often several times in one day. There are the little white lies, the sins of omission, outright deception. And none of this is necessarily a bad thing, says Maurice Schweitzer, associate professor of operations and information management at the Wharton School of the University of Pennsylvania.\u201cDeception is more nuanced that you might initially suspect,\u201d says Schweitzer, who specializes in behavioral decision research. \u201cYour mom might exhort you never to lie and, in the next breath, answer the phone and tell the telemarketer she\u2019s not home right now. We lie all the time.\u201dLove that sweater! I can\u2019t go out\u2014I\u2019m washing my hair. \u201cA lot of lies we tell are pro-social and help us get along with people better,\u201d says Schweitzer. \u201cDeception is extremely functional and very much a part of the fabric of our lives.\u201dAt the same time, trust is an essential element in all social relationships, including those at work. \u201cTrust is the social glue of the economy. It\u2019s the glue for any transaction,\u201d says Schweitzer. \u201cYou can\u2019t contract for everything. Ideally, at the base there is some trust in individuals, groups and institutions.\u201dAny CIO who\u2019s ever shepherded a big project that came in late, over budget or that simply underdelivered knows just how destructive a broken promise can be to trust between IT and business.Although trust is a core construct in management literature, the focus of much of that research has been detecting deception. Precious little examines what happens after trust is broken. You spent a million more than expected on that SAP implementation that you swore would revolutionize the enterprise and the ROI is nowhere to be found. Now what?So Schweitzer, with Wharton colleagues John C. Hershey, professor of operations and information management, and Eric T. Bradlow, professor of marketing, conducted a series of experiments between 2000 and 2004 to uncover what happens at the intersection of deception and trust. Some of the results surprised even Schweitzer. The bad news? Broken trust, when accompanied by deception, is harder to repair. A simple apology does little to reverse the damage. The good news? Trust is less fragile than most of us think. And a promise to change things followed by visible positive actions can go a long way in mending trust.Schweitzer talked to CIO about his findings and what they can teach the CIO about managing expectations, repairing broken trust and making promises you can\u2019t keep.Why explore the issues at the intersection of trust, deception, apologies and promises?I teach a negotiations class, and deception is a very chronic problem, so that got me to thinking about deception more deeply. A lot of lies we tell are pro-social: \u201cThat dress makes you look terrific!\u201d \u201cWhat a great haircut!\u201d There\u2019s a whole class of lies that help us get along in a much more functional way. At the same time, trust is the glue that holds together any social relationship.If you look at deception literature, an enormous amount is focused on how to catch liars. And there has been a good deal written about the ethics of lying. But there\u2019s little on what happens once somebody lies.The common wisdom has been that trust, once broken, is impossible to repair. Trust recovery is slow or difficult. Or trust recovers, but never fully. People have always talked about trust as if it were glass: easy to break and difficult to repair. As I began to think about deception, that seemed wrong to me. With some relationships, you violate trust and the relationship ruptures completely. But in many settings, particularly the office, the relationship continues. And in many cases, trust gets repaired.The question I wanted to answer was, How does deception harm trust?You tested your theories with a money game. How did you set that up?We had to agree on a definition of trust. The meaning agreed upon was \u201ca willingness to accept vulnerability based upon positive expectations about another\u2019s behavior.\u201dTo find out what happens when that trust is harmed, individuals were paired with each other in a trust game involving money. One player in each pair (the \u201codd\u201d player) was given $6 in each round, which they could either keep or pass to the other person (the \u201ceven\u201d player). If the odd player kept the $6, the round ended and the even player got nothing. If the odd player passed the $6 to the even player, it tripled to $18 and the even player could decide how much to return to the odd player.We used money because it gave participants something they actually cared about. They were trusting this money to someone with the expectation that if they did, that money would grow and the other person would return some of it to them. Why would I loan you money? You do that with the expectation that you\u2019ll receive something positive from that going forward.We explored how trust is harmed by untrustworthy behavior and untrustworthy behavior accompanied by deceptive behavior, and how apologies, promises [and] subsequent trustworthy behavior affected trust.A key aspect of our experiment favored trust recovery. We didn\u2019t let the relationship rupture. Players had to continue playing even when one acted in an untrustworthy manner. But relationships sometimes rupture. If your spouse violates your trust, you may separate. But if your boss does, you may just have to deal with it. The relationship may or may not recover.What did you discover?We went in with a clear set of predictions that the assumption that trust is extraordinarily fragile is not right. And our results suggested it was not right. We found that trust could be effectively restored when individuals observed a consistent series of trustworthy actions, such as having money returned to them each round. Or when a promise was made to change: \u201cI give you my word. I will always return $9 every round, including the last one.\u201d People were very receptive to that. In fact, we were surprised how quickly trust was restored. And in some cases, the trust eventually recovered completely. The promise to change, however, only worked initially if it wasn\u2019t accompanied by a delivery on that promise. Trust recovered a bit but it never fully recovered. It leveled off after awhile as if [the injured party] had written that person off.When a person\u2019s trust was violated\u2014and that violation included deception\u2014it was much more difficult to restore, even when followed by a series of trustworthy actions or promises. We didn\u2019t anticipate just how harmful deception would be to trust. We also thought that an apology would be more effective in trust recovery than it was. The apology\u2014\u201cI really screwed up. I shouldn\u2019t have done that. I\u2019m very sorry I tried taking so much these last two rounds\u201d\u2014did little. We thought that it would be more effective.It may be that the apology didn\u2019t go far enough. Apology has to be perceived as sincere. It has to indicate remorse and a plan to change. An effective apology can be powerful. But \u201cI\u2019m sorry\u201d just isn\u2019t good enough.What can CIOs learn from this research?Be very careful about making promises or commitments you can\u2019t keep. Inevitably there is going to be a time when\u2014intentionally or unintentionally\u2014you let people down. But you should recognize that if a relationship doesn\u2019t rupture completely, chances for rebuilding trust are very high.When it comes to CIOs, people may have inflated expectations of IT. Or there may be deadlines that they expect you to meet that you miss. There\u2019s also something called a psychological contract. For example, an IT employee has a psychological contract with the CIO that involves what the worker expects that isn\u2019t written down. Those are almost invariably violated because no one is sure of those expectations. Then there are things a CIO might never have promised\u2014daily backups of data\u2014but people assumed the IT department was doing.It\u2019s impossible to manage every expectation. So it\u2019s important to figure out what you need to do to repair it after a trust violation occurs. One of the most important lessons from the research is that words can be very powerful in repairing relationships, specifically in repairing trust. But for words to be powerful, they have to be credible. And for them to be credible, you can\u2019t have lied to people in the past. In fact, you can\u2019t have even overpromised in the past. For example, if you are going to lay people off, a CIO should not say, \u201cI\u2019m going to lay off 200 people and that one action will put us on track and everyone else will be safe.\u201d Making that kind of statement with conviction risks credibility you might need later if you have to come back and say, \u201cWe need to do another round of layoffs.\u201d Employees won\u2019t buy it.If you\u2019re a new CIO coming into a situation where there\u2019s no trust in the IT department, it might serve you well to make a very specific promise about how things are going to change. A promise to change can be very effective. But you need to make sure that the actions you\u2019re taking are clearly observed. Make sure that employees can see your staff coming in on Saturdays to get that project done. Have the IT staff interact more with the business so they know what\u2019s going on. People are usually willing to give you a chance, but you have to work hard to follow through on the promises you make.Does context matter when trust is broken?A critical question for managers across industries involves the role of trust in their business and the nature of the violation. When Arthur Andersen committed accounting violations, the firm faced a serious threat to its business. They were selling a seal of approval. When that seal is less credible, it has less value. But when Martha Stewart commits an accounting violation, she has not fundamentally threatened her business\u2014aside from her absence\u2014because she is selling style advice. Advice about decorating is not related to her lying.The message of my research is that trust recovery can happen, but the receiver needs to believe the message and perceive that he hasn\u2019t been lied to previously. Senior managers at HP or Enron would have needed to convince their audience that the untrustworthy act would not be repeated, and they would want others to observe their future behavior. This can take the form of voluntary decisions to \u201copen their books\u201d or have independent auditors inspect their work. Greater transparency can be a big help.Understanding how trust works is key for executives\u2014like CIOs\u2014who work globally.Yes. One strength of the U.S. economy is that most Americans are trusting. They trust its institutions. You can fly to Cincinnati, sign a contract, get back on the plane and assume the deal you signed is going to happen.In many developing economies, that\u2019s not the case. Business becomes encumbered by rituals that have been put in place to develop relationships. You can\u2019t meet a total stranger and agree on a large transaction in a short period of time. China is the obvious example. If you\u2019re doing business there, it\u2019s essential to develop relationships and spend a lot of time going to banquets and making toasts and traveling to different events. The building block for business there is trust in the individual. American companies have a lot of trouble when they swap out managers there every few years or so and the new manager has to start all over to build that relationship and that trust.You\u2019ve researched the effects of emotions on trust. How does that tie in?We looked at the influence of incidental emotions on trust. You get a speeding ticket just before a board meeting. Or you find out you got a promotion before meeting with a new vendor. We did extensive tests to find out how emotions influence trust judgments.We found out that they have a very big impact. When you go into that meeting with the new vendor, you\u2019ll ask yourself, \u201cDo I trust them?\u201d And if you just don\u2019t know, you\u2019ll go to your emotions. \u201cHow do I feel? I feel pretty good.\u201d You\u2019ll make a positive trust judgment based on emotions unrelated to the actual situation.It\u2019s important to take that into account when trying to earn or keep trust. That\u2019s why a really good salesperson may tell a joke to try to affect someone\u2019s emotion. If you encounter someone in an emotional state that might negatively influence their judgment, there are three strategies. Change the emotion: Tell a joke or comment on the weather. Recognize the source of emotion: \u201cI was really sorry to hear what happened to your house.\u201d Or harness good emotions: \u201cI heard your kid got into Stanford!\u201d You have to be emotionally savvy.
