In logical reasoning it is important to check each causality connection between two entities to ensure that it is clear and irrefutable.
When communicating logic, people tend to check the statements that are made against their internal logic. Many times things just “Do not make sense to us”. TOC suggests a protocol how to discuss such situation in a productive and respectful way.
The process of checking logic is called scrutinizing that has its own terminology and sequence – Categories of Legitimate Reservations, CLR.
There are seven categories with the help of which we check for:
2. Entity Existence
3. Causality Existence
4. Cause Insufficiency
5. Additional Cause
6. “House on Fire”
7. Predicted Effect Existence
