R0021/2026-03-25/Q001/H3¶
Statement¶
Formal definitions exist but contain qualitative terms (e.g., "judgment," "benefit of mankind") that do not provide operationally precise criteria for distinguishing engineering from adjacent disciplines in all cases.
Status¶
Current: Partially supported
The definitions do exist and converge, but they contain qualitative elements alongside their quantitative distinguishing criteria.
Supporting Evidence¶
| Evidence | Summary |
|---|---|
| SRC02-E01 | ECPD definition includes "applied with judgement" and "for the benefit of mankind" — qualitative terms |
| SRC01-E01 | ABET student outcomes include "make informed judgments" and "recognize ethical and professional responsibilities" — partially subjective |
Contradicting Evidence¶
| Evidence | Summary |
|---|---|
| SRC01-E01 | ABET criteria do include measurable elements: mathematical/scientific knowledge, experimental competence, design capability |
| SRC02-E01 | ECPD definition specifies "mathematical or physical sciences" as the knowledge base — a clear, testable criterion |
Reasoning¶
The definitions provide a clear primary distinguishing criterion (mathematical/scientific foundation) but also include qualitative elements that resist precise operationalization. This means the definitions effectively distinguish engineering from trades or crafts (which lack the scientific foundation requirement) but are less effective at distinguishing engineering from applied science or technology management.
Relationship to Other Hypotheses¶
H3 refines rather than contradicts H1. The definitions exist and converge (supporting H1), but their distinguishing power has limits (the nuance captured by H3). H2 remains eliminated.
