Gyrfalcon writes the analysis pieces. The name is a pen name, after the Nordic falcon: it is a handle, not a person.
How these articles are written
- Assumptions come first, before any result, so it is clear what a figure depends on.
- Results sit in tables, with the arithmetic shown step by step and a link to every source.
- The strongest objection to a rule of thumb is stated before it is answered, and what cannot be answered is said plainly.
- No country is the default. Where a famous figure comes from US data or US law, the article says so.
- The articles describe what studies, data and other writers have found. They do not tell anyone what to do with their money.
