Quotes from Keith E. Stanovich

It seems perverse to define intelligence as including rationality when no existing IQ test measures any such thing!

Substantial empirical evidence indicates that individual differences in thinking dispositions and intelligence are far from perfectly correlated. Many different studies involving thousands of subjects have indicated that measures of intelligence display only moderate to weak correlations (usually less than .30) with some thinking dispositions (for example, actively open-minded thinking, need for cognition) and near zero correlations with others (such as conscientiousness, curiosity, diligence).

More intelligent people appear to reason better only when you tell them in advance what good thinking is!

attribute substitution amounts to substituting an easier question for a harder one.

Dysrationalia is the inability to think and behave rationally despite adequate intelligence.
