Research methodology

A transparent method for turning evidence into decision-ready Brazil expansion research.

The method is designed to keep facts, estimates, scenarios and operating observations distinct. It does not convert incomplete evidence into false certainty.

Method

Eight steps from question to published evidence

The method is designed to keep facts, estimates, scenarios and operating observations distinct. It does not convert incomplete evidence into false certainty.

01

Define the executive decision and the population, geography and time period it concerns.

02

Search primary and official evidence first; use independent market sources where official data cannot answer the question.

03

Record source, publication date, observed period, geography, units and access date before transformation.

04

Normalize currencies, periods, units and definitions without hiding the original observation.

05

Label every material claim by evidence type so readers can distinguish facts from interpretation.

06

Triangulate material claims when a single source is insufficient or commercially interested.

07

Publish methodology, assumptions, sample constraints and limitations next to the conclusion they affect.

08

Version meaningful changes, set a review date and correct or retire stale material rather than silently preserving it.

Authors & editorial responsibility

E2M currently publishes its institutional author and internal editorial owner. Named external expert reviewers appear only after onboarding and a completed scoped review; no external reviewer is implied by an empty seat in the network.

Evidence hierarchy

Source selection

Higher tiers do not make every number automatically comparable; geography, period, definition and methodology still need to match the question.

Tier 1
Official / statutory

Government agencies, legislation, regulators and official registries.

Tier 2
Official statistics / multilaterals

IBGE, central banks, OECD, World Bank and comparable statistical bodies.

Tier 3
Independent market evidence

Established research firms, industry datasets and independently collected market data.

Tier 4
Provider / commercial evidence

Published provider pricing, commercial documentation or direct quotes; never presented as a market average.

Tier 5
Discovery only

Blogs, forums, social posts and AI outputs may surface leads but are not final evidence for material claims.

Claim labels

Facts are not estimates.

Material claims carry a label that preserves what kind of knowledge they represent.

Update & correction

Material numeric research receives a stated observation period and review date. If a source becomes stale, unavailable or contradicted by stronger evidence, the asset is corrected, versioned or retired.

Research boundary

E2M Research can explain operating implications. It does not replace legal, tax, accounting, employment, customs or investment advice.
