Accepting functions are our priority area for processing information: when working with them, we don’t feel internal tension. On the other hand, Producing functions are what we have to use when interacting with new information, so their work is felt more by us as a kind of compulsion. In other words, these properties set the goal (what is important to us in and of itself) and the tool (what we need for something) in working with information.
It is important to understand that accepting/productive are deep properties of our thinking, so their manifestations are extremely difficult to trace in ourselves, let alone to determine with the help of leading questions. Thus, when determining a type, it is necessary to look not at the properties separately, but at the signs formed by them.
The accepting functions include Leading (1), Role (3), Suggestive (5) and Ignoring (7) functions. The producing functions include Creative (2), Vulnerable (4), Mobilizing (6) and Demonstrative (8) functions. These function properties are the basis for dividing types into the pair of traits Rational/Irrational.
Rational are types with accepting rational and productive irrational aspects, while Irrational are types with accepting irrational and productive rational aspects.
