Countries with large electricity-access gains from 1990 to 2023 should usually show large under-5 mortality reductions over the same development window.

supported

confidence cueThis is a clear pass for the claim as written. It still applies only to this sample, period, and method.

policy briefNeeds review

In ordinary language

Over a long period, do more market-oriented institutions translate into higher income or productivity, once the comparison looks beyond a single success story?

plain answer

The data clearly moved in the predicted direction. supported

why it matters

Growth claims can look convincing in single success stories. This test asks whether the pattern survives a broader comparison.

how the test works

It compares 56 country or place units from 1990 to 2023, using a descriptive design.

what was measured
What changed
  • Electricity access gain
What we checked
  • Under5 mortality decline
what this does not prove

A single test is not the whole truth. It narrows the claim under a specific sample, time period, and method. Strong policy conclusions need the pattern to survive nearby tests, alternative data, and serious objections.

Who has skin in the game — schools predicting on this

1 school list this hypothesis as a test of their position. The chips below are school-level scoreboard outcomes, not a second hypothesis verdict.

hypothesis verdict vs scoreboard outcome

The banner verdict judges this hypothesis as written. The scoreboard asks whether each school's polarity-corrected prediction was right. Raw status is not a school win: SUPPORTED supports schools that needed SUPPORTED, but refutes schools that needed REFUTED.

Falsification criterion — what would disprove this

set before the run · honoured after

This hypothesis is considered falsified if:

SUPPORTED if n>=40, at least 70% of selected countries reduce under-5 mortality by >=50%, and the median decline is >=60%. REFUTED if fewer than 50% pass or the median decline is <40%. Otherwise PARTIAL.

Interpretation

This is a descriptive structural-screen verdict using local WDI/OWID vintages. It grades the predeclared pattern, not a causal effect of a single policy lever.
