3What is Theory?
- Theory is a set on interconnected statements or
propositions that explain how two or more events
or factors are related to one another
4Example
- Children who experienced harsh and inconsistent
punishment are more likely to become deviant
Harsh Inconsistent Punishment
Violence
5Two ways to build a theory
- Deductive Approach (theory, hypothesis, research
design, observations, empirical generalizations,
new theory) - Inductive Approach (research design,
observations, empirical generalizations, new
theory)
6Examples
Inductive approach
Deductive approach
- Physical abuse in childhood is associated with
future violence - Is child neglect also related to violence
perpetration later in life? - Survey of a group of incarcerated criminals about
their childhood experiences - Theory about how the impact of child neglect is
similar/different from child abuse in terms of
its criminogenic effect
- How do burglars select their targets? (research
question) - Field study of active burglars
- Face-to-face interviews with burglars about the
ways they select the targets - Theory about how a household can become a target
for burglary

8Criteria for Evaluating Theory
- Logical consistency
- The scope
- Parsimony
- Testability
- Empirical validity
- Usefulness and Policy implications
9Logical consistency
- Propositions of a theory have to be logically
stated and internally consistent
10The Scope
- The Scope of a theory refers to the range of
phenomena which it proposes to explain - A theory that accounts only for the crime of
check forgery may be accurate, but it is
obviously very limited in scope - Gottfredson and Hirschi posit that both imprudent
and criminal behaviors can be predicted by a
common characteristic lack of self-control
11Parsimony
- Parsimony (simplicity of theorys structure)
- The theory based on fewest assumptions and
requiring the fewest propositions is considered
the superior theory
12Differential Association Theory is based upon
these nine postulates
- 1. Criminal behavior is learned
- 2. Criminal behavior is learned in interaction
with others persons in a process of communication - 3. The principal part of the learning of criminal
behavior occurs within intimate personal groups - 4. When criminal behavior is learned, the
learning includes techniques of committing the
crime, which are sometimes very complicated,
sometimes simple and the specific direction of
motives, drives, rationalizations, and attitudes - 5. The specific direction of motives and drives
is learned from definitions of the legal codes as
favorable or unfavorable to committing deviant
acts
13Differential Association is based upon these nine
postulates
- 6. A person becomes delinquent because of an
excess of definitions favorable to violation of
law over definitions unfavorable to violation of
the law - 7. Differential associations may vary in
frequency, duration, priority, and intensity - 8. The process of learning criminal behavior by
association with criminal and anticriminal
patterns involves all of the mechanisms that are
involved in any other learning - 9. While criminal behavior is an expression of
general needs and values, it is not explained by
those general needs and values, since non
criminal behavior is an expression of the same
needs and values
14Testability
- Testability by objective and repeatable evidence
(theory which are untestable are not scientific)
15Untestable theories
- A theory may propose that males who rob banks are
motivated by an unconscious impulse to resolve
their guilt over their childhood sexual
attraction toward their mothers
16Untestable theories
- If we find enough bank robbers who fit this
description, then the theory is supported - If research uncover that bank robbers claim their
only motive is money then that does not mean that
the theory is rejected - Denial of these feeling by robbers supports the
theory, because the same unconscious impulse that
motivated them to rob also rendered them
unconscious of their true motivation
17Empirical validity
- Empirical validity means that a theory has been
supported by research evidence - None of the theories is found to be entirely true
or false - The questions is, what degree of empirical
support does the theory have (weak or strong)
18Usefulness and Policy implications
- Every criminological theory implies a therapy or
policy - The better the theory explain the problem, the
better it is able to guide efforts to solve the
problem
19Causation in criminology
- Causation is a relationship that holds between
events, objects, variables, or states of affairs
20Can we observe causality?
- It is not possible to detect a cause empirically
- We can rarely directly sense a cause
- We merely induce their existence from our
experience of the association of two or more
events - Can we observe how a hard blow to the arm causes
a bruise?
21Causality
- How do we know if A causes B?
- Time
- Association
- No other factor causes both (spuriousness)
22Time
- It is usually presumed that the cause
chronologically precedes the effect - In a strict reading, if A causes B, then A must
always be followed by B. - Smoking and lung cancer (What goes first?)
23Association/correlation
- Changes in X cause changes in Y
- For example, football weekends cause heavier
traffic, more food sales, etc. - We must be very careful in interpreting
correlation coefficients - Just because two variables are highly correlated
does not mean that one causes the other
24Examples
- Ice cream sales and the crime rate are correlated
(both increase during summer) - The number of cavities in elementary school
children and vocabulary size have a strong
positive correlation
25Spuriousness?
26Spuriousness?
27Spuriousness?
28Spuriousness?
29Controversy around causation
- Not all scholars agree that uncovering
discovering the universal laws that underlie
human behavior should be a focus of our research
30What is different about people?
- Human beings are qualitatively different from the
objects of study in the natural sciences (rocks,
stars, chemical compounds, etc) - Humans think and learn, have an awareness of
themselves and their past - These unique human characteristics are the reason
for the debate how criminology should look like
31Examples of subjective realities
- Elephant and four blind men
32More examples (four temperaments)
- The same situation
- evokes absolutely
- different reactions.
- How can we apply causation here?
33Thomass theorem (1928)
- Another argument against causality
- If people define situation as real, they are
real in their consequences - This theorem is related to the subjectivity of
reality - Examples?...
- What do you think of causality in sociology now?
34How to solve the problem of causality?
- Interpretative approach does not say that social
behavior is chaotic - There is some pattern in human behavior
- But this pattern is not due to the causal laws
- It is created out of the system of social
conventions people generate during their
interactions
