Using a recently developed theoretical framework called Hypothetical Thinking Theory, Jonathan St. B. T. Evans provides an integrated theoretical account of a wide range of psychological studies on hypothesis testing, reasoning, judgement and decision making.

Jonathan St B. T. Evans is Emeritus Professor of Cognitive Psychology at the University of Plymouth and founding and former editor of the international journal Thinking & Reasoning. He has published numerous experimental studies of thinking, reasoning, judgement and decision making, as well as several other books on these topics. He has investigated a number of cognitive biases and explored their implications for human rationality in earlier writing. He is probably best known for his development of dual-processing accounts of thinking and reasoning, a form of which provides the theoretical framing for the current book.
