- N/A Not applicable to this hypothesis
Diagnosticity Analysis¶
Most Diagnostic Evidence¶
| Evidence | Why Diagnostic |
|---|---|
| SRC02-E01 | The actual Ipsos 31-country survey does not contain the 66% figure — decisively eliminates H1 |
| SRC03-E01 | Identifies the probable actual source of the 66% figure — discriminates between H2 and H3 |
Least Diagnostic Evidence¶
| Evidence | Why Non-Diagnostic |
|---|---|
| SRC01-E01 | Confirms phenomenon exists at Ipsos but doesn't cleanly discriminate between hypotheses |
Outcome¶
Hypothesis supported: H2 — The phenomenon is real but the attribution is wrong.
Hypotheses eliminated: H1 — The 31-country Ipsos survey does not contain the 66% figure. H3 — The underlying phenomenon is well-documented.
Hypotheses inconclusive: None.
