The facts on the card
The card carries these facts from its Wikipedia article.
- John Maynard Keynes published a version of the paradox in 1921.
- Daniel Ellsberg popularized the paradox in his 1961 paper, "Risk, Ambiguity, and the Savage Axioms".
- It is generally taken to be evidence of ambiguity aversion, in which a person tends to prefer choices with quantifiable risks over those with unknown, incalculable risks.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ellsberg paradox article was read about 35,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 32: each hit it takes is cut by 13 %.
