This makesggplot2 very powerful, because you are not limited to a set of pre-speci?ed graphics, but you can create new graphics that are precisely tailored for your problem. This grammar, based on the Grammar of Graphics (Wilkinson, 2005), is composed of a set of independent components that can be composed in many di?erent ways. 1 Welcome to ggplot2 ggplot2 is an R package for producing statistical, or data, graphics, but it is unlike most other graphics packages because it has a deep underlying grammar. Anyone who wants to understand either needs The Book of Why.ДЎ. It shows us the essence of human thought and key to artificial intelligence. Pearl's work enables us to know not just whether one thing causes another: it lets us explore the world that is and the worlds that could have been.

His work explains how we can know easy things, like whether it was rain or a sprinkler that made a sidewalk wet and how to answer hard questions, like whether a drug cured an illness. The causal revolution, instigated by Judea Pearl and his colleagues, has cut through a century of confusion and established causality-the study of cause and effect-on a firm scientific basis. 'Correlation is not causation.' This mantra, chanted by scientists for more than a century, has led to a virtual prohibition on causal talk. This edition is revised and expanded, with a new introduction lessДЄ Turing Award-winning computer scientist and statistician shows how understanding causality has revolutionized science and will revolutionize artificial intelligence It might not make you any smarter, but The Mismeasure of Man will certainly make you think.-Rob Lightner The revised edition includes a scathing critique of Herrnstein and Murray's The Bell Curve, taking them to task for rehashing old arguments to exploit a new political wave of uncaring belt tightening. The 20th-century obsession with numbers led to the institutionalization of IQ testing and subsequent assignment to work (and rewards) commensurate with the score, shown by Gould to be not simply misguided-for surely intelligence is multifactorial-but also regressive, creating a feedback loop rewarding the rich and powerful. When one measure was found to place members of some 'inferior' group such as women or Southeast Asians over the supposedly rightful champions, it would be discarded and replaced with a new, more comfortable measure. European men of the 19th century, even before Darwin, saw themselves as the pinnacle of creation and sought to prove this assertion through hard measurement. How did scientists decide that intelligence was unipolar and quantifiable? Why did the standard keep changing over time? Gould's answer is clear and simple: power maintains itself.

Gould's brilliant, funny, engaging prose dissects the motivations behind those who would judge intelligence, and hence worth, by cranial size, convolutions, or score on extremely narrow tests. How smart are you? If that question doesn't spark a dozen more questions in your mind (like 'What do you mean by 'smart,'' 'How do I measure it' and 'Who's asking?'), then The Mismeasure of Man, Stephen Jay Gould's masterful demolition of the IQ industry, should be required reading.

The definitive refutation to the argument of The Bell Curve.
