Diagnosticity Analysis¶
Most Diagnostic Evidence¶
| Evidence ID | Why Diagnostic |
|---|---|
| SRC02-E01 | A widely-read article on a major platform (Substack, reaching HN) is incompatible with both H2 (no prior use) and H3 (limited/informal only). It maximally discriminates between H1 and the alternatives. |
| SRC04-E01 | Physical lab coats at a hackerspace in 2011 demonstrate institutional adoption and physical-world usage, which is incompatible with both H2 and H3. |
| SRC01-E01 | Four dated dictionary entries spanning 15 years from four different authors. The time span and author diversity make this incompatible with H3 (limited) as well as H2 (none). |
Least Diagnostic Evidence¶
| Evidence ID | Why Non-Diagnostic |
|---|---|
| SRC07-E01 | Additional slang dictionary entries may be derived from Urban Dictionary content (SRC01), reducing their independence. They confirm H1 but do not add significant discriminating power beyond SRC01. |
| SRC06-E01 | A GitHub repository name confirms usage but could be explained under H3 (a single informal instance). It supports H1 but does not strongly discriminate against H3 on its own. |
Outcome¶
Hypothesis supported: H1 — The term "pretendgineer" (and variant "pretengineer") has extensive documented prior uses across multiple public source types, multiple communities, and at least 17 years of history.
Hypotheses eliminated: H2 — Every piece of evidence contradicts the claim of no prior use. H3 — The breadth, diversity, and duration of usage far exceeds any reasonable definition of "limited" or "informal only."
Hypotheses inconclusive: None — the evidence is unambiguous.
