The title of this study is inspired by Daniel Kahneman’s best-selling book Thinking, Fast and Slow. In it, the Nobel Prize winner explains in great detail the working of two systems of human reasoning: System 1, which is fast, automatic, associative, subconscious, involuntary and (nearly) effortless, and System 2, which is slow, intentional, logical, conscious, effortful and requires executive control, attention, and concentration. This distinction applies to human categorization as well. Each of the two labels refers, in fact, to a set of systems, which is why the designations Type 1 and Type 2 processes are preferable. The default-interventionist architecture presupposes the constant automatic activation of categories by Type 1 processes and interventions of Type 2 processes if necessary. Type 1 categorization relies on the ‘shallow’ linguistic representation of the world, while Type 2 uses ‘deep’ extralinguistic knowledge. A series of linguistic examples are analyzed to illustrate the differences between Type 1 and Type 2 categorization. A conclusion is drawn about the need to take this distinction into account in psycholinguistic and linguistic research on categorization.
