Reputation and Trust
Uncertainty and Risk
What are the Solutions to Uncertainty in the
Social Environment?
Proxy’s and ‘inferred trustworthiness’
Herd behavior
If everyone is using it, it has to be
good…right?
Closed Systems versus Open Systems
3rd party reputation is perhaps the most
common solution
What about when reputation is not possible
(or practical)?
3
Reputation as a Solution to the Problem of
Uncertainty: Information Asymmetries
Problem of Lemons (Akerlof, 1970)
Information
asymmetry in the
marketplace
4
What constitutes a reputation?
What they do…
Foster good behavior
Punish bad behavior
Reduce risk in long term
Transmission can be word-of-mouth, or
more chronicled directly
Reputations concern people and
organizations, not things.
To be effective, require clear criteria and
incentives
Explicit or Implicit?
5
Positive, Negative and Mixed Reputation
Systems
Positive
Start at a baseline, can only go up.
Negative
Start at a baseline, can only go down.
Mixed
Start at a baseline, can go below or
above baseline

Party Reputations to Work...
Must have permanent identities.
Must make the feedback
available for others to inspect.
Individuals have to actually pay
attention to and use the
reputations.

Trust and
Trustworthiness
Trustworthiness
Assessing Trustworthiness
Treated as a ‘characteristic’
Involves initial, one-shot interactions between parties
Theoretically linked to perceived competence and motivations of a
given partner
Competence to act in a way we deem appropriate
Motivation to act in our best interests

Example Study Examining Trustworthiness:
Online Sale Survey
Assessing Trustworthiness
Tseng and Fogg (1999)
[from Hertzum Anderson, et al]
First-hand experience
Reputation
Surface ‘attributes’
Stereotypes
First-hand experience is essential to building ‘trust’, as well as 3rd party
reputations
Surface ‘attributes’ and ‘stereotypes’ more accurately about assessing
trustworthiness.
12
Approaches to Trust
Psychology
Trust as “personality trait” (dispositional trust)
Trust as learned experience (learned trust)
Philosophy
Trust versus reliance and other concepts
Sociology
Trust as behavior (situational trust)
Through risk and uncertainty
Other factors such as the medium (i.e., CMC)
Perceptions based on characteristics: assessment of
trustworthiness
Trust as cognitive: It is reflected in attitudes about
another’s desire and ability to act in a positive way
towards us in a given context.
13
“Trust concerns a positive expectation
regarding the behavior of somebody
or something in a situation that entails
risk to the trusting party.”
“Trust exists whether it is explicitly
recognized or not”
(Marsh and Dibben)
Trust-Building in Sociological
Sense
Trust-building
Involves
repeated interactions between parties
Theoretically
linked to risk in the social exchange
situation (e.g., what is at stake in the interaction?)
Trust
is not the same as cooperation
Trust-building
can involve various types of uncertainty,
which is also distinct from risk. (e.g., how confident are
we in a particular outcome?)
15
Locus of Trust
Interpersonal Trust
Organizational Trust
Do
organizations ‘trust’?
Society-level Trust
“general
trust”
16
Trust versus Reliance
Role of Betrayal
If we rely on someone to do
something, if he/she/it does not do
so we are disappointed.
i.e., inanimate objects (car
brakes, computer)
Role of ‘monitoring’ systems
Monitoring and surveillance of
individuals: trust, distrust, or
reliance?
17
Trust in Information and Information Systems
“providers”
E.g., virtual agent representations
“trusted systems”
But is it really “trust” or just
reliability?
