⚪ Play the Ellsberg Paradox


Choose the urn with the most red balls and get $1000
P.S. This is just a demonstration. You're not really going to get money.

Urn A
50 red • 50 blue
(Known probabilities)
Urn B
100 balls total
Unknown red/blue mix
The Ellsberg Paradox shows that people often prefer a gamble with known probabilities over one with unknown probabilities, even when the unknown gamble could be better. This tendency is called ambiguity aversion.
