# Human Engineering
**Domain:** Human Factors / Biotechnology / History of Technology
**Doc Type:** Terminology Node
**Maturity:** Developed
## Definition
**Human engineering** is an historically ambiguous term. In aerospace, military and industrial literature it commonly refers to human factors: designing controls, displays, tasks and machines around human capabilities and limitations. In contemporary biotechnology discourse, similar wording may be heard as genetic, reproductive or physiological engineering.
## Interpretation Rule
The meanings must not be silently collapsed.
**Human factors:** engineer the system around the person.
**Biological engineering:** intervene in biological processes or materials.
[[wiki/1969 Moonshot and Reproductive Engineering|1969 Moonshot and Reproductive Engineering]] preserves this distinction when comparing Cold War aerospace terminology with the contemporaneous externalization of human fertilization through [[wiki/In Vitro Fertilization|IVF]].
## Key Insight
**Shared vocabulary is evidence of conceptual proximity, not proof of shared institutional purpose.**
