As I explained in a previous review,
      I am interested in trust in the context of agent computing. The blurb made
      this book sound ideal:
  
        what, precisely, is trust?
      
How can it be achieved and sustained?
      
... how can it be regained once it has been broken?
                
    
    The authors distinguish three kinds of trust: naive trust, that
      unreflective innocent trust of a small child with no concept of betrayal;
      blind trust, that self-deceptive wilful denial of any evidence of
      betrayals; and authentic trust, reflective and honest, the mature
      trusting relationship that the book is concerned with. The first two are
      what most people think of as trust, and why they then have problems in how
      to sustain, and regain, trust. Additionally, because people use the
      metaphor of trust as a fragile thing, it can consequently be too
      easily broken, and difficult or impossible to mend. But
      authentic trust is an ongoing process, a relationship that
      incorporates the concept of distrust; such authentic trust can be
      negotiated, built, and rebuilt. 
    
    They are careful to point out that this mature relationship requires
      honesty, which can be painful, rather than the destructive cordial
      hypocrisy that smilingly says everything is fine while knowing it is
      not, leading to the impossibility of trust. Authentic
      trust is created when you come to be unafraid of the negative assessments
      of people you respect. By the same token, trust is destroyed by flattery
      or cordial hypocrisy. These are simply lies, and when
      people lie to you, you cannot trust them, their assessment of the
      situation, or their promises.
    
    The authors emphasise that trust is so valuable because it provides the
      freedom to engage in projects one could not, or would
      not undertake on one's own. But much of the current
      philosophical focus is on trustworthiness, which leads to the
      paradox of not being able to rationally trust until trustworthiness has
      been established, yet being unable to establish that trustworthiness
      without first trusting. So how can we rationally trust? However, the
      paradox rests on a misconception of trust: if there are guarantees that
      the trusted party is indeed trustworthy, there can be no authentic
      trust, simply reliance or predictability. To be real trust, it must
      entail the possibility of betrayal.  This is because people are not
      reliable or predictable in the way that laws of nature are, but they do
      have interests and desires, which may conflict with our own.
      Trust is restricted to agents, beings (usually people
      or human institutions) who have a choice, who make decisions, who have
      attitudes, beliefs, and desires, who respond to our acts and gestures with
      feelings, acts, and gestures of their own.  So the authors move
      the focus to the trusting, rather than the trusted, side of the
      relationship, and explain how it is possible to perform the act of
      trust rationally. To break the paradoxical deadlock, the trust
      relationship must begin with the act of trust, not the establishment of
      trustworthiness, and must explicitly include recognition of the
      possibility of breaches and betrayals of that trust. Trust is not earned,
      it is given. 
    
    The authors are also careful to point out that not all breaches of trust
      are equal. The fragile thing metaphor encourages us to believe any
      breach will shatter trust beyond repair. But there are several forms of
      breaches of trust. Since not all these breaches are equal, the responses
      should not be equal. And, with the focus on the entire relationship, not
      the single breach, the response should be context dependent.
      What counts as a ... breach of trust should always be
      considered within that larger framework [of the entire relationship]. It
      is a question of keeping in mind what really counts. In
      particular, they point out that circumstances can change, and so promises
      may need to be renegotiated in the light of new understanding. They
      emphsise this such requests for renegotiation are not a breach of trust,
      but actually a confirmation of the trusting relationship.
    
    Breaches occur for many reasons. Sometimes things just don't work out,
      and it is nobody's fault. Sometimes someone makes a mistake, someone is at
      fault, yet focusing on the relationship rather than
      the outcome gives us the navigational tools to overcome, if not overlook,
      mere mistakes. Next are the real breaches of trust,  maybe due
      to arrogance or insincerity, rather than being mere mistakes. These
      require apologies to maintain the authentic trust relationship.
      An apology is a statement of intention to redeem
      oneself, and the beginning of a conversation about how this can be done.
      Then we come to indifference, or lack or caring, and finally to genuine
      betrayal. Focusing on the relationship, rather than the metaphor of  fragile
      thing, even full betrayals can be overcome: this requires the act of
      forgiveness. Forgiveness is an action, a ritualised undoing of the
      act of betrayal. But in the same way that an act of trust changes both
      parties and the relationship, so an act of betrayal and forgiveness
      changes things; the relationship does not return to what it once was. This
      is part of the property of authentic trust: it is a dynamic, changing
      process that must be worked at and maintained. 
    
    This focus on the trusting party also helps focus on the essential
      property of self-trust, trust or confidence in one's own ability
      to trust wisely. Trust is a skill that can be learned by doing, but this
      skill begins at home: If you do not trust yourself or
      your ability to behave correctly in a difficult situation, you may well
      find it difficult to have faith that others can do so. You also must trust
      yourself to have a good sense of people, to choose to trust people who are
      likely to be trustworthy rather than, for instance, because you find them
      charming or attractive. ... If you do not trust yourself to choose wisely
      the people you trust or with whom you form relationships, you may have a
      good deal of trouble trusting people. 
    
    All these points are important, and interesting, and act as an essential
      a first step in clarifying terminology and metaphors, and setting the
      stage for building authentic trust. It has certainly clarified many
      concepts for me, and given food for thought. But I am also interested in
      the promised descriptions of how this authentic trust can be achieved, and
      regained, in practice, and there was very little concrete said on this
      topic. I would have liked to see a further section of examples (and
      advice?) on building such relationships.
    
    Some longer quotes:
    
  
It is often suggested that widespread
      distrust is stimulating the current interest in trust. We think that the
      truth is more subtle and interesting: there is more trust in the world
      than ever before, and the increasingly global dependence on trust spurs
      both our interest in and our need for trust. In situations of distrust,
      people do not talk about trust but rather develop strategies for coping
      with its absence. 
                      
  Both trust and distrust tend to be
      self-confirming, and it is easy to see why. If one person trusts another,
      the second person, knowing that he or she is trusted, will be more likely
      to be trustworthy, thus confirming the trust on the part of the first
      person. The psychological reward of trust is that it is gratifying to be
      trusted. It is also gratifying, in a more profound way, to trust. Trust
      indicates respect, and trust creates a bond (if only, at first, the bond
      of trust). The problem with thinking about trust as an attitude toward
      other people is that it ignores the reciprocal nature of trust.
      Most people respond to trust by being trustworthy, making further trust
      all the more likely. 
                      
  Simple trust, the sort of trust that is
      celebrated in a well-cared-for dog, is not the paradigm to follow, but
      neither is the lawyer's fantasy of an "ironclad" contract.
      
... Blind trust is denial. ...
      
Too often, trust as such is confused with blind trust ..., and trust
      as such is taken to exclude criticism, scrutiny, and "objective"
      consideration of the evidence. If "objective" means simply "impartial,"
      this is true. To trust is to be committed, and thus to be partial. But
      trust need be neither blind nor simple. 
                      
  Trust can be prudent, measured,
      reflective, and conditional and still be authentic, not blind. Part of the
      problem with trust is that too many people refuse to consider as trust any
      trust that is prudent, measured, and conditional. We suggest, to the
      contrary, that blind trust is not really trust at all. In religious
      contexts, it might better be called faith, but in secular contexts, it is
      best identified as foolishness. To confuse such uncritical acceptance and
      willful denial of all possible counterevidence with trust is to
      misunderstand trust in the most profound way. The equation of trust with
      blind trust leads to the conclusion that it is never wise to trust. Trust
      becomes a vice instead of a virtue, a liability instead of a strength.
                
  predictability requires a high degree of
      probability, even a kind of (psychological) certainty. Trust requires
      something else: a reciprocal relationship in which questions of
      probability take a back seat to questions of mutual expectations,
      responses, and commitments. Analyses of trust in terms of predictability
      miss this essential aspect of trust, the element of reciprocity. In what
      we call reliance, predictability (combined, perhaps, with a certain amount
      of control) is definitive. One must still make decisions about whether to
      rely or not rely on something, given the possibility or probability of
      failure or disappointment. But what is not present in reliance that is
      crucial in trust (and distrust) is that the person trusted has intentions
      and motives and makes his or her own decisions, with or without regard for
      the other person's decision to trust.
                      
  We do not merely predict and control the
      behavior of other people. We reason with them. We appeal to their
      emotions, their sympathies, their fears, their hopes and desires. ...
      corporations have interests and strategies, and this leads us to consider
      them in human terms.
      
     Machines ... do not have interests and
      strategies. ... But if corporations have interests, even if they are only
      narrow economic interests, and they behave strategically, then they can be
      appealed to, negotiated with, depended on (or not) to fulfill their
      commitments. 
                      
  Failing to trust someone is not merely an
      omission. It is unethical not to trust people when they are
      plausibly trustworthy, just as it is unethical to treat them unfairly. In
      fact, refusing to trust people may be more damaging to them than treating
      them unfairly, for the latter fails only to give them what they deserve.
      The former limits their capacity to act as full human beings. 
                      
  Simple trust is unreflective. Blind trust
      is self-deceptive. Authentic trust is both reflective and honest with
      itself and others. All forms of trust involve counting on other people,
      and, as such, they all are vulnerable to betrayal. But whereas simple and
      blind trust experience betrayal as earth-shattering, betrayal is neither
      surprising nor devastating to authentic trust. All trust involves
      vulnerability and risk, and nothing would count as trust if there were no
      possibility of betrayal. But whereas simple trust is devoid of distrust,
      and blind trust denies the very possibility of distrust, authentic trust
      is articulated in such a way that it must recognize the possibilities for
      betrayal and disappointment. It has taken into account the arguments for
      distrust, but has nevertheless resolved itself on the side of trust.
      Authentic trust is thus complex, and it is anything but naive. Authentic
      trust is not opposed to distrust so much as it is in a continuing
      dialectic with it, trust and distrust defining each other in terms of the
      other. 
                      
  We are all painfully familiar with
      bureaucratic moods, which are often conflated with "policy."
      Such moods dictate a retreat from personal responsibility and judgment,
      typically in the name of following rules. 
                      
  our moods and emotions do not happen to
      us. We choose them. To think of trust as an emotional phenomenon is to
      accept that trust begins (and ends) with care, and it is also to embrace
      the idea that trust is a personal choice and within our realm of
      responsibility. This suggests a philosophy of life. Human life is a series
      of emotional engagements and projects, in which we invent a shared future
      through our moods and emotions. To believe otherwise is to cut ourselves
      off both from other people and from the power we each can bring to our
      lives by working together and trusting one another. 
                      
  Sometimes trusting ourselves is actually
      much like trusting another person. We find ourselves waiting to see how we
      will behave in some emergency or emotionally charged situation, for
      instance. ... Some people think that self-trust means the absence of all
      anxiety, total self-confidence, but they are wrong. Fear and anxiety are
      indications of uncertainty, and trust necessarily involves uncertainty. It
      is the absence of fear and anxiety that may mark the lack of true
      self-trust. Their total absence more likely indicates indifference or
      ignorance, or perhaps a simple trust that is bewildered and devastated
      when we do fail ourselves. 
                      
  Just as care is an essential ingredient of
      trust of every kind, lack of caring and indifference stand as antitheses
      to trust. Cynicism, even when it presents itself as serious and sincere,
      is often a self-deceived form of indifference. One pretends not to care
      when one really does care, or one intends not to care because one does not
      want to be responsible for doing anything about the situation. But between
      cynicism and indifference, there is only a philosophical difference: the
      cynic claims to have a philosophy of life to justify his or her
      irresponsibility.
                      
  Lying is in itself a breach of trust;
      indeed, by some standards, the ultimate breach of trust. Lying embodies a
      wholesale insincerity---stating as truth what one fully knows not to be
      true---and it may also manifest a profound lack of caring, even when the
      lie (a "white" lie) is intended to protect the feelings of the
      person to whom the lie is told. In such cases, one may well care about the
      feelings of the person, and that is a form of care. But it is a
      shortsighted, limited notion of care, and it may cause violence to the
      longer-term relationship. ... But many lies are not so white, and not
      intended to protect the feelings of the recipient. They are rather
      designed to protect the liar from the consequences of his or her actions.
      Thus Kant, in a judgment that captures the viciousness of some lies, says
      that lying is a violation of the very humanity of the person lied to, a
      denial of his or her human dignity. 
                      
  Compensation is repayment, where the
      betrayal consisted of some quantifiable good. Money is the most obvious
      example. When the betrayal is financial, as in many securities fraud
      cases, the idea of "measure for measure" would seem to have a
      precise meaning. Compensation in this sense could thus be assimilated to
      the more general concepts of debt and repayment. That would be misleading,
      however, because what must be compensated for is not merely the financial
      loss but also the betrayal. Thus the apparent quantitative objectivity
      gives way to something much more subjective. And when the loss due to the
      betrayal is entirely made up of such intangibles as pride, status,
      self-confidence, and trust, the notion of compensation begins to look
      troublesome indeed.
