Welcome to the Tyler Lab in the Social Psychology Program
at NYU
Current Research
My research group is concerned
with a variety of issues broadly related to the dynamics of authority within
groups, organizations, and societies. As psychologists, our particular
interest is in the factors that shape people's motivations when they are
dealing with others in group settings.
Because
justice has been found to be especially important to people's motivation
when dealing with others, we study social justice. In particular, our
work focuses on the psychology of procedural justice - the fairness of
group rules and processes. Research consistently finds that people
are strongly influenced by their assessments of procedural justice when
they are evaluating authorities and institutions.

Law and Regulation

Research
I explore the motivations that
lead people to cooperate when they are within groups. There are two aspects
of such cooperation. First, there is deference to authority. The study of
regulation is generally concerned with understanding why people accept the
decisions made by others. Legitimacy, the quality of being viewed as being
entitled to be obeyed, is consistently linked to exercising authority in
fair ways.
Because of its implications for
regulation, my work has always shared a connection with the concerns of the
field of law. The question of how to manage undesirable behavior is central
to the work of legal authorities, and I examine the motivations that shape
people's rule-related behavior. My primary book on this topic (
Tyler
, 1990) establishes the key role of legitimacy in shaping obedience to the
law. That finding is important to bringing psychology into social regulation,
since the study of law-related behavior had been dominated by economics analysis
linking behavior to sanctions. My work shows that people will also take one
the responsibility for obeying the law when asked to do so by a legitimate
authority. In other words, people become self-regulatory. The further finding
in my work that procedural justice is a key antecedent of legitimacy has
led to a literature on procedural justice in legal institutions and in interactions
with legal authorities.
The book which
best articulates these findings is Why People Obey the Law. The findings
of this book have been widely cited within law. They are important because
the question of how to motivate compliance with law and legal rules is
central to many areas of law and these findings therefore have wide applicability.
Recent applications include the study of commitment hearings in mental
hospitals, people's reactions to mass tort settlements, the emergence of
international law, and the popularity of mediation hearings.

My most recent contribution to this
literature is my book Trust in the
Law (Tyler and Huo, 2002) which explores deference to legal authorities
among minorities. This book builds upon the earlier book Why
People Obey the Law and again shows that procedural justice is a key
antecedent of deference and of legitimacy. However, in Trust
in the Law, ethnic group differences are more directly addressed. This
book argues that legal authorities can build on the strong procedural justice
findings I outline in my work to create a new model of regulation. I refer
to that model as process-based regulation.
Trust in the Law is based on a sample
of interviews with White, African-American, and Hispanic residents of these
two cities. The focus of the study is on people's voluntary acceptance
of decisions made by legal authorities. The results show that people's
willingness to defer to legal authorities is shaped by two social motivations:
procedural justice and motive-based trust. This finding suggests that authorities
have considerable ability to gain deference from community members by treating
them in ways that encourage judgments that the procedures used are fair
and the motives underlying actions are benevolent. The study indicates
that treating people with dignity and respect heightens both of these judgments.

Trust
and confidence in the police and courts
A second project using this approach
explores people's overall trust and confidence in the legitimacy of the police
and the courts. This set of studies is concerned with the way that the average
community resident makes evaluations of legal authorities, irrespective of
whether they have had a personal experience with those authorities. Again,
the question I am concerned with is the degree to which process issues shape
public evaluations. A contrasting view is that often associated with the
NYPD and its aggressive policing policies. That view is that the middle class
is primarily interested in crime reduction and accepts the occurrence of
unfair treatment toward, at least, minorities in the service of that goal.
Several studies of mine suggest that this belief is not correct. In a reanalysis
of previously collected surveys, I showed that people's evaluations of the
police and courts are heavily influenced by procedural justice based judgments.

Citizen's
Voice Project: Giving New Yorkers a say on police policy
More recently, I have been studying
public views about the police and policing activities a sample of New Yorkers
will be interviewed this summer about their views on the police, as well
as about their personal experiences with police officers through interviews
over the telephone with New Yorkers.
Why do these interviews? We live
in the midst of difficult and changing times. The events of September 11th
highlight the risks of terrorism in
America
, while recent budget reductions make clear that we are living in a time
of fiscal limits. No agency is more strongly affected by these changes than
the New York City Police Department. To most effectively manage policing
activities during these changing times, we need to have a clear understanding
of how the public views the police. It is for this reason that we are conducting
interviews with the residents of different neighborhoods in
New York City
. The interviews provide valuable feedback to those managing the police department
and the city about public views regarding the activities of the NYPD.
To
this end, I have been conducting surveys of the residents of
New York
to better understand how people feel about policing services in their neighborhoods.
These surveys have been conducted during the summers of 2001 and 2002, and
2003. Everyone interviewed has been randomly chosen to represent the views
of the people in their neighborhood. The opinions they express are confidential,
and no one is ever told the identity or opinions of any individual who participates
in the surveys. Instead, the views of all of the individuals interviewed
are combined and the overall views of New Yorkers are presented.

The
Psychology of Justice
I am interested in understanding why people
care about and react to their evaluations of the fairness or unfairness of
procedures. The procedural justice effect has emerged as a robust and compelling
one, with people shown to react to how decisions are made in a wide variety
of groups, organizations, and societies.
In early studies, I looked at
psychological models of the justice motive, and argued that people are concerned
about issues of identity and status. Further, I suggested that people use
the justice of procedures to tell them about their status and to evaluate
the degree to which they want to define their identity in terms of groups
to which they belong (Lind and Tyler, 1988; Tyler and Lind, 1992).
This idea unfolds in my work two
ways. First, in the finding that people care about the fairness of procedures
more than about the favorability or fairness of outcomes. Early justice research
focused primarily on issues of equity (outcome fairness) on the assumption
that outcomes are the key issue. My work helped to shift the focus to issues
of procedure by showing the importance of procedural justice judgments.
Second, my work helped to establish
that people do not view procedures in instrumental terms, i.e. as a way to
obtain outcomes. That view is explicit in the classic work on procedural
justice by John Thibaut and Laurens Walker (1975). Instead, procedures are
valued because they communicate status and inclusion in groups (Lind and
Tyler, 1988). This distinction between instrumental and value-expressive
or relational motivations underlying procedural justice effects has transformed
the way that psychologists think about the meaning and implications of procedural
justice findings.
I have extended this line of thinking
to the study of authority relations (Tyler and Lind, 1992) arguing that people
view group authorities as representatives of the group, and are therefore
sensitive to how those authorities exercise their authority. Using fair procedures
to exercise authority both communicates that the people one is dealing with
are respected by the group, and it suggests that the group is one that is
worth identifying with and being involved in.
Most recently, my work has sought
to understand the relationship between justice and identity. I view justice
as a key issue that people focus on when trying to define themselves and
their relationship to their group.

Multiculturalism
The dynamics of authority are central
to all models of governance. Hence, my work on the basis of deference to
authorities has been important in discussions about how to govern society.
In particular,
I have written about the problems associated with governance in diverse,
multicultural, societies. As I noted above, Trust in the Law discusses issues of diversity and multiculturalism
as those issues are important to the rules of law.

Cooperation
in Groups/Management:
P
rocedural justice encourages people to involve themselves in groups by engaging
in voluntary cooperative actions to help the group. This is true in communities,
with government, and in work settings. Tyler and Blader (2000) examine this
connection in work settings, showing that employees are strongly influenced
by the fairness of group decision-making procedures.
My work also connects with the field
of organizational behavior in schools of management. It has been widely
demonstrated that many key work-related behaviors (job performance, absenteeism,
turnover, sabotage, etc.) are shaped by the procedural justice of the workplace.
As in other arenas, management theory has been dominated by models that
root human motivation in incentives and sanctions. Hence, this demonstration
that there are broader motivations on which managers can draw has been
widely noticed. In particular, discussions about work increasingly recognize
the importance of motivating voluntary (extra-role) behavior in workers.
This type of behavior is especially poorly motivated by incentives and
sanctions. As a consequence, the social psychological model must become
more central to our understanding of work related behaviors.
My recent
work seeks to develop a framework within which to understand motivation
in work settings. I have conducted interviews with a sample of employees
in
New York
companies (Tyler and Blader, 2000) and have studied corporate bankers in
a large multinational firm. At this time, I am conducting a panel study of
a sample of American workers through Knowledge Networks. My goal in this
work is to develop arguments about the impact of work climate on the behavior
of those within them. Instead of stressing mechanisms of accountability linked
to rewards and punishments, my basic argument is that those employees who
are treated fairly by their superiors will be motivated to perform well on
their jobs.
