Four modes of processing

If we describe the processing as:

inputs -> (statements, algorithms) -> outputs

and consider that statements and algorithms can be certain and uncertain everyone.

There are exist only 4 types of processing.

• calculations (certain statements, certain algorithms)
• reactions (certain statements, uncertain algorithms)
• thinking (uncertain statements, certain algorithms)
• feeling (uncertain statements, uncertain algorithms)

Type	Statements (Data/Inputs)	Algorithms (Rules/Logic)	Description
Calculations	Certain (C)	Certain (C)	Deterministic and Formal. The outcome is precisely known given the input and rules. Focus on precision and proof.
Reactions	Certain (C)	Uncertain (U)	Adaptive and Heuristic. Known input triggers a rule set that is still being learned, optimized, or is inherently probabilistic. Focus on rapid, learned responses.
Thinking	Uncertain (U)	Certain (C)	Inference and Logic. Firm, formal logic is applied to fuzzy, incomplete, or probabilistic inputs to deduce a likely conclusion. Focus on logical deduction under uncertainty.
Feeling	Uncertain (U)	Uncertain (U)	Intuitive and Interpretive. Both the input data and the rules/model used to process it are ambiguous, subjective, or constantly evolving. Focus on holistic interpretation and intuition.
