The Democratic Empire of Rationalist Science is a gargantuan, efficient nation, ruled by Lord Tau with a fair hand, and renowned for its daily referendums, multi-spousal wedding ceremonies, and irreverence towards religion. The compassionate, democratic population of 27.216 billion Rational Scientists are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The enormous, outspoken government prioritizes Education, with Industry, Welfare, and Healthcare also on the agenda. It meets to discuss matters of state in the capital city of Vivaldi. The average income tax rate is 91.4%, and even higher for the wealthy.

The frighteningly efficient Rationalist economy, worth a remarkable 3,320 trillion Credits a year, is mostly made up of the Information Technology industry, with significant contributions from Tourism and Arms Manufacturing. State-owned companies are common. Average income is an impressive 121,996 Credits, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Mantis shrimp studies is academia's fastest growing field, builders across Rationalist Science are blocked up with orders for new public loos, the family summer vacation has become a thing of the past following the introduction of the year-round school year, and shopkeepers use microscopes to verify the authenticity of banknotes. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Rationalist Science's national animal is the Nexu, which frolics freely in the nation's many lush forests, and its national religion is Secular Atheism.

Rationalist Science is ranked 309,398^th in the world and 17^th in New Hyperion for Highest Disposable Incomes, with 10,491.72 Standard Monetary Units.
