Dienes provides an introduction to some foundational topics that are sorely missing from the typical Psychology degree programme — the philosophy of science (from several different perspectives) and a conceptual comparison of three main methods of statistical inference: the frequentist, Bayesian, and likelihood approaches. The book could have benefited from a more meticulous editor, but Dienes’s writing is, for the most part, clear and insightful, and he provides very useful suggestions for further reading.
I would highly recommend this book (alongside the free Coursera course on “Improving your statistical inferences” by Daniel Lakens) to anyone interested in the logic behind empirical science. (And I do hope that most students of related fields would feel spoken to here.)
