Everyone has theories – they are about how we perceive reality, and we try to make common sense
of these experiences.
- Interpretaion of reality
- Is what everybody is doing
- Everybody has theories
We test our theory to see how it works in reality and based
on the feedback we receive; we make abstraction again and
apply it to our common sense as to how we see the reality.
However
• Any good social scientist knows that the facts do not speak for themselves Theoretical
structures are critical.
• Why do things happen in the way they do, theoretical concepts are critical.
Reality
- Is one thing, but what it means, does not speak for itself -> many interpretations
Here they say: theory is critical to understand it
To understand it particular: the why of an observed
o Why question is critical to scientist
o If we understand the why, we can influence the outcome
• Theories consider Concepts
Concepts -> abstracts or generic ideas -generalized from particular instances-> lead us to
theories
Generalized from paricular instances
From concepts to theories
When does something becomes a theory?
Theory:
Belongs to the family of words that includes guess, speculation, supposition, conjecture, proposition,
hypothesis, conception, explanation, model.
- If everything from a ‘guess’ to a general falsifiable explanation has an Inge of theory to it, it
becomes more difficult to separate what Is theory from what isn’t.
- Behind every idea you can see a theory, so if everything becomes a theory, what is than so
special about theories? What are we interested in?

From common sense to science Common sense:
- Can be based on simple ideas to interpret reality.
Science:
- Is doing the same thing but trying to interpret
reality on the basis to sound theoretical
inside.
Theoretical or scientific models help us perceive
the reality/ theories.
• We apply these models to understand the
reality and from reality we go back to
abstraction (research methods &
modeling techniques)
• From here, we go back to science to help us understand the reality.
So, in science, we do the same that we normally do but in a more strict manner.
• How? By using existing theories and knowledge or models in order to understand what we
observe.
• However, In order to do this properly: we need good theory.
4 key criteria for good theory:
o Explicit -> how the relationships are expected.
o Measurable
o Generalizable -> should have a larger meaning.
o Falsifiable -> should be testable, in principle it should be possible.
Theory
System of statements targeted at describing, explaining, and predicting a real world
phenomenon.
o Consists of constructs (concepts- What) and propositions (relationships between
constructs)
o That collectively present a logical, systematic, and coherent explanation of the real world
phenomenon within certain boundaries (different context like time settings).
Example:
Transaction cost theory stipulates that high transaction costs encourage firms to insource the
making of a product or service.
- They help us understand when the costs are too high and that we should produce in
house.
o Transaction costs depend on Asset Specificity, Uncertainty or Frequency.
Game theory: Concerns analyzing strategies to deal with competitive actions.
Theory is used in science to understand what is happening in the real world.

Theory is about abstraction from the observable
More abstract way:
Theoretical Plane
- In reality you observe many simple things
- Analyze theories, at the theoretical level.
Empirical Plane ->
• Testing of theoretical insights: cause -> effect ->
consequence
For example: some very intelligent students in classroom,
we observe they get on average higher grade point averages,
the consequence is better class performance, effect is
perhaps the result from higher grades
- In empirical plane we see something happening, a
cause and a consequence.
- Call the cause: the independent variable.
Outcome: dependent variable
Variable
• Observable (Manifest)
• Measurable
• representation of an abstract construct
Example:
Independent variable -> intelligence -> is observable (can see in classroom), is measurable.
(IQ), representation of an abstract construct (Yes, you can say you represent intelligence)
• Scientific thinking -> on the empirical plane
o We use variables -> very important in our analysis.
A hypothesis:
- States (expected) relationships between variables
- Is empirically testable
- Is stated in a falsifiable form.
A hypothesis specifies the expected relationship between IQ score and grade point avg.
• IQ score and grade point averages are operations measures of intelligence and academic
achievement.
Example:
- Relationship here expected between IQ & grade point average.
- Sill the empirical plane
o The ride from what we observe in the real world.
o Understand the relationship -> understand the why? Why is this happening.
o Than we need theories -> & than we need constructs?
