open access: greenSSRN Electronic Journal, 2011
The Ellsberg paradox is often cited as evidence for unknowable "ambiguity" versus computable "risk", and a refutation of the Savage axioms regarding expected utility maximization and the program for revealing "subjective" or "belief-type" probabilities.

open access: green, 2021
Decades of empirical and theoretical research on human decision-making has broadly categorized it into two, separate realms: decision-making under risk and decision-making under uncertainty, with the Allais paradox and the Ellsberg paradox being a prominent example of each, respectively.
