'Redirect' promises to reveal the 'surprising new science of psychological change', a technique that Timothy Wilson calls 'story editing': redirecting the 'narratives' we tell ourselves about our personal and societal problems. One example of this is in academic underachievement. First-year university students often find the new academic landscape to be a difficult transition from previous experiences, and commonly grades suffer, leading to underachievement or attrition. Wilson contrasts two 'narratives' when faced with disappointing results: student A tells himself that he's not cut out for university, whereas student B tells herself that early setbacks are common and she'll need more effort and a different approach. The first student drops out and the second turns things around. The key concept here is the self-fulfilling prophecy: if you believe you can, you're right; if you believe you can't, you're right. All that's needed is for people to edit their narratives to look more like student B.
Although that's the essence of the story editing approach - changing your beliefs into more rational and helpful ones - very little of the technique is anything new. Rational emotive behavioural therapy (REBT) and cognitive behavioural therapy (CBT) have been outlining this technique since the 1950s. Further to this, the writer takes liberties with his story editing technique, folding in various psychological findings that only have a glancing similarity to his concept. He includes James Pennebaker's writing technique and borrows from behavioural activation therapy, ideas that don't even seem superficially related to Wilson's own definition of story editing.
Not only is the story editing argument rather weak, the main focus of the book is actually more to do with experimental design that psychological change. Wilson spends most of the book arguing for the use of randomised controlled studies, and the need for them in assessing social policies such as sexual health interventions and drug abuse education. Fair enough - high quality research is the reason why doctors don't prescribe leeches - however, the excessive focus on research methodology gets tedious, with the words 'random assignment to conditions' appearing on every other page. In all, there's little new here!
