Few would question that humankind is the crowning achievement of evolution-that history yields progress over time from the primitive and simple to the more advanced and complex-or that identifying an existing trend can be helpful in making important life decisions. We have always identified trends as bad or good. But Stephen Jay Gould argues that this mode of interpretation is a bias that needs correcting. In Full House, Gould presents the truth about progress, evolution, and excellence, as well as a different way to understand trends other than as entities moving in a definite direction. Gould examines how the misinterpretation of data and statistics can result in bad science and social policy, while focusing on the nature of excellence from Plato to Darwin and the misconception that progress is inevitable.
