Claim	C002

Matrix¶

	H1: Claim accurate	H2: Partially correct	H3: Materially wrong
SRC01-E01: 80/20 ratio recommendation	++	+	--
SRC02-E01: Hard negatives serve distinct function	++	+	--
SRC03-E01: LLMs have systematic negation weaknesses	+	+	-

Legend: - ++ Strongly supports - + Supports - -- Strongly contradicts - - Contradicts - N/A Not applicable to this hypothesis

Diagnosticity Analysis¶

Most Diagnostic Evidence¶

Evidence	Why Diagnostic
SRC02-E01	Discriminates between H1 and H2 by establishing that hard negatives serve a function positive instructions cannot replicate — "necessary" not just "helpful"

Least Diagnostic Evidence¶

Evidence	Why Non-Diagnostic
SRC03-E01	Supports both H1 and H2 — explains LLM negation weakness but does not distinguish between "necessary" and "helpful"

Outcome¶

Hypothesis supported: H1 — The evidence consistently supports the claim that both instruction types are needed.

Hypotheses eliminated: H3 — No evidence supports the idea that positive instructions alone suffice.

Hypotheses inconclusive: H2 — Plausible but not supported by the evidence pattern; the literature frames the relationship as complementary and necessary.
