About & Methodology

What DEX publishes, how the research is produced, and how to suggest corrections or collaborations.

About DEX

DEX is an independent, student-led business research and publishing project. I study business and accounting and use this site to turn long-form research into practical, readable industry intelligence.

The goal is not to predict which company or asset will win. It is to build a durable body of work that explains how industries developed, how their value chains and business models work, where credible growth signals exist, and which risks could change the outcome.

What This Site Publishes

  • Industry reports covering history, market structure, value chains, economics, competition, regulation, and risk.
  • Structured datasets and tools that make assumptions visible and let readers inspect or test the numbers.
  • Video explainers that translate the core findings into a faster format.

Each format supports the same research system: one research project can become an article, a dataset, a visual explanation, and a video without changing the underlying evidence.

Research Methodology

1. Define the question and scope

Every report begins with a specific question, a geographic and time scope, and a set of definitions. When different sources use different market definitions, the report treats them as different estimates rather than combining them into false precision.

2. Prioritize stronger sources

Sources are generally considered in this order:

  1. Government agencies, regulators, statistical offices, and company filings.
  2. International institutions, peer-reviewed research, and established industry bodies.
  3. Reputable research firms, major financial institutions, and well-sourced journalism.
  4. Secondary summaries used only as discovery aids or context.

Published research should link material claims to specific sources, including the source’s date, geography, market definition, and unit. A source list alone does not establish which source supports a particular estimate. The 50-industry screening dataset retains its original market sizes, growth figures and projections as unverified research leads. Separate historical baselines have been source-checked for semiconductors and cybersecurity; broader prescription-medicine context accompanies the biopharmaceutical row. Each added record includes its own year, unit, geography, market definition, publication date and review date. A partial or context status applies only to that separate record: it does not verify the original screening estimate or forecast. Original-source fields remain empty until the corresponding original claim is verified. A contextual reading link is also not evidence for the row’s numbers.

3. Separate evidence from interpretation

Reported figures, editorial classifications, scenarios, and DEX interpretations are not the same thing. Tools on this site label calculated outputs as scenarios. Categories and maturity labels are editorial judgments intended to make comparison easier; they are not official classifications.

4. State uncertainty and limitations

Forecasts are sensitive to definitions, base years, exchange rates, regulation, and adoption assumptions. Missing data is shown as missing rather than silently replaced. A dataset update date records when the file was edited, not when each underlying source was published or checked.

5. Review, update, and correct

As reports are revised, key numbers and links should be checked against cited material; where that review has not happened, the limitation is stated alongside the data. Substantive corrections or new data may be reflected in the report’s last-updated date. If you find an error, please send the exact page, claim, and supporting source to [email protected].

Use of AI

AI tools may assist with discovery, outlining, translation, formatting, code, and production. They are not treated as evidence. Factual claims should be checked against the cited public sources, and final editorial responsibility remains with DEX.

Independence and Disclaimer

Unless a page clearly states otherwise, the content is independently produced and no company paid for inclusion. Future sponsored or commissioned work will be labeled. Nothing on this site is investment, legal, accounting, or medical advice.

Contact and Collaboration

Corrections, source suggestions, dataset feedback, sponsorship inquiries, and research collaborations are welcome.

Support the Research

If this work is useful, you can support it by sharing a report, subscribing on YouTube, starring the website repository, or using GitHub Sponsors. These actions help fund more research and better datasets.
