I extend Machina and Schmeidler’s (1992) model of probabilistic sophistication to unbounded uncertain prospects (acts) and derive risk preferences over the induced probability distributions (lotteries) with unbounded support. For example, risk preferences can be derived over normal, exponential, and Poisson families of probability distributions. My extension uses a version of Arrow’s (1970) Mon...

The sophistication of a string measures how much structural information it contains. We introduce naive sophistication, a variant of sophistication based on randomness deficiency. Naive sophistication measures the minimum number of bits needed to specify a set in which the string is a typical element. Thanks to Vereshchagin and Vitányi, we know that sophistication and naive sophistication are e...

The article by Salvatore et al. (1) in this issue of Clinical Cancer Research describes the synthesis and biological activity of an improved, recombinant immunotoxin targeted to the CD22 B-cell antigen. This particularly well-performed study is one of a large series of significant innovations in the field by this and other groups of investigators in the last few years. To appreciate more fully ...

There is little research on the role of personality in musical expertise. We address this gap in the literature by using data from a large national study (N = 7870) to examine how scores on 10 facets of the Big Five dimensions of personality predicted self-reported musical sophistication and performance on two behavioral tests (melodic memory and rhythm perception). Personality predicted musica...
