Sample investigation · Research and education

Two harvest figures, one season

A research team needs a defensible number. A ministry and a trade body publish different totals, and the press picks whichever it met first.

Grain harvest down sharply this season, officials say

Two sources give two totals. The gap is partly method: one counts planted area, the other counts delivered grain.

The dispatch as it arrived

The headline gives a direction and no number. The team starts by asking which number each source means.

Grain harvest down sharply this season, officials say

Two sources give two totals. The gap is partly method: one counts planted area, the other counts delivered grain.

The question

Which figure can the study cite, and what has to be stated alongside it?

02 Sources

Count the origins, not the reports.

An origin is the first to report something. A repeat only passes it on. Counting origins shows how many separate voices there really are.

A graph of 5 sources from this sample investigation. 3 are origins or primary documents, which are the first to say something or a document a reader can open. 2 only repeat them. Agriculture ministry table, primary; Grain trade body table, primary; Agency wire, quotes ministry, repeat; Business daily, quotes trade body, repeat; Specialist weekly, compares both, origin.

Details: The source ledger

The source ledger

Both totals come from primary tables, and the press mostly repeats one or the other. The ledger shows the specialist weekly as the only item that sets both side by side.

03 Six-axis audit

Thin evidence on what and where.

The audit asks who, what, when, where, why and how. Each question gets its own confidence from 0 to 100. A weak answer is marked contested instead of being averaged away.

A six-axis audit of this sample investigation, confidence by axis: Who 90; What 62, contested; When 88; Where 66, contested; Why 60; How 92. Illustrative sample.

The six-axis audit in full

How is the axis that explains the gap: area survey against delivery records. What and where are marked contested because the size and the regional split depend on that method.

Six-axis audit

2 contested
  1. Who

    Ministry and trade body, each for its own total.

    90
  2. What

    A fall in harvest. The size depends on the method.

    Contested
  3. When

    The current season, to the end of August.

    88
  4. Where

    National. Regional splits differ between sources.

  5. Why

    Dry spell, per both. Weighting of causes differs.

04 Impact

Nine areas of life. Environmental leads.

The impact matrix does not forecast. It lists where the claim, if it holds, would touch each of nine areas, and how strongly.

Nine impact areas for this sample investigation, from most to least affected: Environmental 70, adverse; Supply chain 60, adverse; Economic 54, adverse; Humanitarian 48, adverse; Political 40, mixed; Financial 36, mixed; Technological 12, mixed; Legal 8, mixed; Security 4, mixed. Illustrative sample.
