Claim. Six rungs are read in order and report the first link not demonstrated among the five that carry a pass rule, and a failed rung means a link was not demonstrated rather than that the effect is absent.

Type. design · Support. stated

Holds when

• The ladder exists because a null is more useful when its location is known.
• The descriptive composition rung never stops the ladder, which is why five of the six carry a pass rule.

Source quote

A null is more useful when its location is known. Six rungs, read in order, report the first link not demonstrated among the five that carry a pass rule: collapse, the oracle premise, whether the weights tracked reliability on held-out keyed items, measured by a Spearman correlation (Spearman 1904) whose 95 percent lower bound must exceed 0. 3, whether the weights improved the validity of what the pool accepted, a descriptive composition rung that never stops the ladder, and retention itself. A failed rung means a link was not demonstrated, not that the effect is absent.
