AI risk and evidence

Guides, glossary entries, explainers, questions, comparisons and statistical literacy.

Build a careful route from the GDP indicator and its institutional metadata to total-versus-per-person comparisons, percentage change and a game about choosing the measure that fits the question.

Move from Italy's durable country identity to European relationships, economic measures, percentage literacy and a country-clue game without turning one national statistic into a national score.

Follow a planet from durable facts to NASA missions, scientific models and a current data release, keeping observations, instruments and conclusions in the correct order.

Italy is a southern European republic extending into the Mediterranean. Its geography, regions, institutions, long historical record and membership of the European Union create many connected routes through the knowledge library.

Mars is the fourth planet from the Sun, a cold rocky world with a thin atmosphere, two small moons and geological evidence of ancient water. It connects planetary facts to missions, instruments, models and uncertainty.

NASA and NIST are United States federal organizations that produce public technical knowledge, but their missions and outputs differ: NASA centres on air and space, while NIST centres on measurement science, standards and technology.

GDP and GDP per capita begin with the same production aggregate but answer different questions. One describes total economic scale; the other divides that total by population to create a per-person average.

The release turns a mission milestone into inspectable evidence. Researchers can begin comparing several kinds of measurements while the remaining instrument datasets continue through preparation.

The release is a useful example of why a percentage needs its time comparison, adjustment method, coverage and revision status before it becomes an economic story.
