What is Research
- Research is the systematic or organized investigation of materials and sources in order to establish facts and reach new conclusions.
- Components of research includes observation, measurement/analysis, interpretation/results

What is research Methodology
- The process used to collect information and data for the purpose of making policy decisions.
- The methodology may include publication research, interviews, surveys or historical information.

Why Study Research Methods?
CJ professionals are both consumers and producers of research
Need to know how to critically evaluate research reports and determine whether appropriate methods were utilized
Need to know how to interpret research and how to produce accurate research

Two Realities/truths about Learning
Experiential reality – the things we know from direct experience (e.g., if you step on a piece of broken glass you know it hurts) ie empirical research
Agreement reality – things we consider real because we have been told they are real, and everyone agrees (e.g., sun sets in the West)
It is important to remember that agreement reality can be wrong: eg Kansas City Preventive Patrol Experiment see note

Secondhand Knowledge – agreed on knowledge that others give us
Two important sources of agreement reality are:-
Tradition – “accepting things that everyone knows”
or
Authority – trusting the judgment of someone with special expertise
Eg. believing a judge who declares that your next traffic violation will result in a suspension of your driver’s than when your parents say the same thing
Both can be problematic - Prevents innovation or questioning of status quo; may simply be inaccurate

Example
- One of the problems with gaining knowledge through authority arises when we generalize an expert’s knowledge beyond their expertise.
- As presented in the following example, news outlets commonly seek out movie stars, entertainers, and famous athletes to provide commentary on issues outside their expertise.

Example
In a 2003 Tucker Carlson of CNN interviewed Britney Spears. During the interview he asked her whether she was opposed to the Iraq War—a topic that was of great public controversy at the time. Infamously, Britney replied, “Honestly, I think we should just trust our president in every decision he makes and should just support that, you know, and be faithful in what happens.” Although Britney received a great deal of criticism for her response, this is clearly an illustration of the public’s tendency to extend professionals’ expertise. Being a talented dancer, singer and performer does not make Britney a political expert.

The Role of Science/Scientific Research
Empirical – the production of knowledge that is based on experience or observation
Scientists have certain criteria to be met before the agree on reality of something they haven’t personally experienced
- An assertion must have both logical and empirical support
Epistemology - science of knowing
the investigation of validity
Methodology – science of finding out
Methodology is how social Scientific methods can be used to better understand crime and criminal justice policy

Personal Human Inquiry
- Human inquiry seeks to explain events and predict future events.
- The key to inquiry/investigation is observation.
- We can never understand the way things work without first having something to understand.
- Understanding through experience means making observations and seeking patterns or regularities in what we observe.
Eg. we learn that getting education will affect the kind of job we have later in life

Personal Human Inquiry
Most people will like to predict how things are going to be in the future
We use causal (relationship b/w cause and effect) and probabilistic (likelihood of multiple outcomes) reasoning to predict the future
The goal is to understand why certain things are related, why patterns occur, to enable us to make more accurate predictions
- Patterns of cause and effects are probabilistic
The effects occur more often when the causes occur than when the causes are absent—but not always

Errors in Personal Human Inquiry
These are common errors we make in our own casual inquiry
Inaccurate observation –
when we fail to observe things right in front of us
When we mistakenly observe things
How to reduce this error:
Observe in a more deliberate way
have a conscious plan to observe
record your answers
use measurement devices eg. taking photos

Errors in personal human inquiry
Overgeneralization –
When we assume that a few similar events are evidence of a general pattern
The tendency to overgeneralize is greater when there is a pressure to reach a general understanding
Eg. a new officer reporting vandalism as the greatest problem in his beat without a thorough investigation
How to reduce this error:
Conducting a large sample of observation
Replication of inquiry ie. repeating a study to be sure the same results are found

Errors in personal human inquiry
Selective observation –
This error occurs once we have established a general understanding that a particular pattern exist
We tend to pay attention to future events that corresponds to that pattern eg. racial or ethnic prejudice
How to reduce this error:
Make a specified number of observations
Base conclusions on all the observations not just the first few respondents

Errors in personal human inquiry
Illogical Reasoning –
Reasoning in a way that makes no sense at all
Gambler’s fallacy – a consistent run of good or bad luck at poker is presumed to foreshadow its opposite
An evening of bad luck may kindle a belief that a winning hand is around the corner
How to reduce this error:
use explicit /clear/unambigous systems of logic

Errors in personal human inquiry
- Ideology and Politics –
CJ professionals may have problems separating ideology and politics from a more detached scientific study of crime
Ideological beliefs may distort how research problems are defined and how research results are interpreted
- How to reduce this error:
guard against its influence
Do not allow ideology & theology to impact the research process

Class Activity
- Illustrations of errors in human inquiry.
- Write down reasons why you may have not done as well in a particular course as you would have liked.
- Classify your reason as either a legitimate reason or an error. If it is an error, identify which of the errors discussed.

Purposes of Research: Exploratory Research
Research in CJ is conducted to explore a specific problem eg exploring the level of bullying in High schools (research topic, see pg. 11 p 2)
CJ prof. research on crime & criminal justice policy in which little is known eg. filicide- killing of one’s child
Also appropriate when some type of policy change is being considered
Might also collect data on some measure to serve as a baseline with which future changes will be compared

Purposes of Research: Description Research
Describe the scope of a crime problem or policy responses to the problem
CJ professionals observes & then describes what was observed. EX. observing criminals in their natural setting & describing how they make decisions
CJ observations and description tend to be more accurate than the causal observations people make about the rate of crime
Descriptive Research are often concerned with counting or documenting observations; exploratory studies focus more on developing a preliminary understanding
Example: Uniform Crime Reports documents and describes crime in the U.S.

Purposes of Research: Explanation Research
CJ research tend to Explain things – answers “Why?”
Examples:
1. Reporting Why some people believe that the police are doing a good job and others do not?
But
Reporting that some people have favorable attitudes toward police is descriptive
2. Reporting why California has the highest auto-theft rate in the nation is explanation.
But
Reporting auto-theft rates for different states is descriptive

Purposes of Research: Application
Applied research is based on a need for specific facts and findings – with implications for policy
Two major types of applied research:
Evaluation research – often used to evaluate the effects of specific CJ programs
Eg. determining if a program designed to reduce burglary was actually effective
Policy/problem analysis – it asks the question “what if” – analysis of general justice policies and more specific problems
Eg. What if ??? – how many new police officers will be hired if a police department shift to a community policing,
Focuses on future events; anticipates future consequences of alternative actions

How to design a Research Project
- Designing a research requires planning, several stages
- But the stages do not always occur in the same sequence
© 2016 Cengage Learning. All Rights Reserved
© 2016 Cengage Learning. All Rights Reserved
Designing a Research Project
Beginning points for a line of research
E.g., interests, ideas, theories (set of ideas intended to explain something), new programs
Theories may produce new ideas or encourage researchers to consider new policies
Why does something occur?
Why is this how it is?
What about this possible program?
These questions may lead to others you might like to explore

Getting Started
Find out what research has been done
Read newspaper stories, journal articles, check out the Internet, talk to relevant people
Figure out your objective and intended audience
Generally, your purpose for undertaking research can be expressed in a report

Conceptualization
Conceptualization: what do you mean by the concept being studied? Clarify what you mean
If you are going to study concern about sexual assault:
Police officers may be concerned about sexual assault because it is part of their jobs
College students might be concerned about sexual assault as a social issue or fear being a victim of sexual assault
You need to specify ALL the concepts you wish to study

Choice of Research Method
- Each available method has strengths and weaknesses
You may choose one after considering the specific concept you want to study
Interviews, surveys, field research, content analysis, official records
The best studies utilize more than one research method

Operationalization
Operationalization: create concrete ways of actually measuring your concept
Sexual assault:
Questionnaire item: “How worried are you about the risk of being sexually attacked while on campus or at college-related social events?”
Worried or Not worried

Population and Sampling
Exactly who or what will you study?
Population – group (e.g., of people) about whom we want to be able to draw conclusions
Since it is generally unfeasible to study ALL members of that population, how will you take a representative sample?
Sexual assault: Will you include full-time and part-time students? Students who live on and off campus?

Observations
Collect the empirical data
Make the observations that you will process, analyze, interpret, apply, and review
© 2016 Cengage Learning. All Rights Reserved
© 2016 Cengage Learning. All Rights Reserved
Analysis
Manipulate the data (usually with a software program like SPSS – Statistical Package for the Social Science)
Goal is to draw conclusions that reflect on the interests, ideas, and theories which initiated our research project
You may begin with calculating percentages
Move to examining frequencies of subsets of your population and explanatory analysis

© 2016 Cengage Learning. All Rights Reserved
Application
Utilize the research you have conducted and the conclusions you have reached
Make your findings known to others
Develop policy to address your findings
Determine what mistakes were made that could be corrected in the future
Determine how your research might feed into future research

Thinking About Research Problems
- One of the most difficult parts of research is developing a research question specific to your interest
- Most researchers reword their research questions as they learn more about the topic
- Begin by finding out more about the topics in which you are interested
E.g. What policies/strategies are significantly correlated with terrorism incidents in U.S.?
Do sentencing policies discriminate against minorities?

Reviewing the Literature
Learn about what is already known about a topic
Process of accumulating, sorting, and synthesizing information on a topic
Organize search around key concepts
Begin with book or article on topic and search its references
Limit search to academic journals and related publications; stay away from websites unless they are sponsored by a college, government agency, or professional organization
Use the library and librarians to develop strategies

How to Read Scholarly Research
Read the abstract first to get information on the purpose of the research, the methods used, and the major findings
Tells you if you need to read the rest of the article and if it is relevant to your research
Skim to article and read the discussion/conclusions to be sure the article is relevant
If the article is relevant, take notes when reading the entire article and mark passages you might want to quote later
After carefully reading it, skim it again to get a broader understanding of the research

Reading a Book-Length Report
- Read the preface or the opening chapter
- Skim the entire book
- For each chapter read the first and last paragraph
- Read it deliberately
- When reading the book, take notes and note questions you have
- You can skip chapters if they are not relevant to your research
