There have been several blogs examining the correlation between Codeforces rating and such scientific factors as IQ or Myers-Briggs, so it's high time to examine the correlation between Codeforces rating and the most important scientific factor: the zodiac sign.

To all you China and Japan simps.

Antarctica is the best in everything

• best weather, never too hot (can always take clothes off if too hot)
• snowy, can make snowman every day
• experience the wonders of perpetual night and day
• aurora borealis
• entire population composed of scientists, highest average iq of any territory
• has 8000 codeforces grandmasters per million inhabitants, compared to measly 0.45 of japan
• protected against war, illegal for most countries to invade
• penguin
