R0029/2026-03-27/Q002 — ACH Matrix¶
Matrix¶
| H1: Predominantly negative | H2: Predominantly positive | H3: Mixed and context-dependent | |
|---|---|---|---|
| SRC01-E01: 46% trust, 66% use, 39% vs 57% split | + | - | ++ |
| SRC02-E01: 36-83% range by country | + | - | ++ |
| SRC03-E01: 52% to 55% trend, 18/26 countries up | - | + | ++ |
Legend:
- ++ Strongly supports
- + Supports
- -- Strongly contradicts
- - Contradicts
- N/A Not applicable to this hypothesis
Diagnosticity Analysis¶
Most Diagnostic Evidence¶
| Evidence ID | Why Diagnostic |
|---|---|
| SRC01-E01 | The trust-use paradox (66% use, 46% trust) is maximally diagnostic — it eliminates both H1 and H2 as complete explanations because people simultaneously demonstrate both positive (use) and negative (distrust) behaviors |
| SRC02-E01 | The 47-point country range (36-83%) eliminates any universal characterization |
Least Diagnostic Evidence¶
| Evidence ID | Why Non-Diagnostic |
|---|---|
| SRC03-E01 | The modest positive trend (52% to 55%) is weak evidence — it could support H2 or H3 nearly equally |
Outcome¶
Hypothesis supported: H3 — Sentiment is mixed and context-dependent. Every evidence item strongly supports this characterization.
Hypotheses eliminated: H2 — No global survey shows majority trust or predominantly positive sentiment.
Hypotheses inconclusive: H1 — Partially supported for advanced economies but not globally. Accurate for specific contexts but fails as a universal characterization.
