4 The Three-Step
Technique – Steps
1 and 2
In this chapter you will learn:
- how we create our own concepts, even when we start out knowing
nothing about the subject; - how to start with your own examples and identify the common
pattern of characteristics that underlies each one; - how to analyse concepts into their essential characteristics.
The three-step technique for analysing concepts begins at the
same point where Semmelweis began. In Step 1 we gather the evidence:
the examples of the concept we want to analyse. Then, in Step 2, we
analyse these examples to extract a common pattern of characteristics.
Step 1: Gather your typical examples
First, like Semmelweis, spend some time gathering the evidence. With
the idea of ‘advertisement’ clearly in your mind, list what you think
might be five or six of the most typical examples. Try to make them as
different as possible. Avoid those for the same type of product or
service, the same producer, and the same medium through which they
are advertised. In this way you’ll be able to strip away their differences
to reveal more clearly their essential similarities.
Step 2: Analyse your examples
Now, using these examples, create your concept. In other words, analyse
the common characteristics in each of your examples, isolating them so
