There is a wealth of books on critical thinking, but very few of them apply specifically to psychology. Of those that do, these are beginning to seem dated, and in addition, it is my belief that the particular style of writing which I have demonstrated in my previous books (perhaps best described as relaxed, accessible and unpretentious) would be particularly apposite to tackle the subject of critical thinking, in the same way that I have aimed to lighten the learning of statistics. Anecdotally, lecturers increasingly find themselves pointing out to students that they would gain better marks if they were more critical and analytical in their work. It seems that students are less prepared for this year on year, as the preparatory ‘A’ level system has focused less and less on critical thinking as applied to psychological theories and arguments. Students themselves, however, often complain that they are told to think and write more critically without really knowing what this means or entails. The book could be sold to all undergraduate psychology students, especially those in their first two years, some ‘A’ level students, and possibly the lower end of postgraduates who still contest with feedback that they could better their work with more analysis. On the back of my first volume on student projects, and what I hope to be a successful second volume on psychological statistics, the impetus is there for this volume to achieve sales substantially over the minimum needed to pursue publication of the intended work with a view to more than a modest profit.
