Transposed conditionals, shrinkage, and direct and indirect unbiasedness.

30 Aug 2008 Unbiasedness as conventionally understood is not a necessary property of good inferences. Such unbiasedness is "direct"--it guarantees that, on average, an estimate equals the thing it is estimating (the parameter). Strange as it may seem, this ... Read more...

Deductive rationality in validating and testing conditional inferences.

30 Aug 2008 We asked people to validate conditional inferences (e.g., "A, therefore C" with "if A then C"). People are more likely to look for falsifications ("A and not-C") versus confirmations ("A and C") given a forced choice. Second, falsification rates ... Read more...

The conjunction fallacy and the many meanings of and.

21 Aug 2008 According to the conjunction rule, the probability of A and B cannot exceed the probability of either single event. This rule reads and in terms of the logical operator wedge, interpreting A and B as an intersection of two events. As linguists have ... Read more...
