designer involved in technology that will be in most readers’ pockets and purses (mobile phones and chip-based credit cards), then a psychologist and always an investor, Tim has spent years analyzing the weird and wonderful behavior of investors, fund managers, securities analysts, and all of the associated members of the global investing community Tim is the creator of the behavioral finance-based website, The Psy-Fi Blog, where he brings his wide-ranging experience and wryly cynical world view to bear on the weird and wonderful world of finance The Psy-Fi Blog offers a unique insight into the application of behavioral finance, through reference to a growing body of research that shows conclusively that we are not as smart as we think we are By linking behavioral finance research to real-world events and showing their connections to other areas of knowledge, Tim constantly aims to remind us that the only proper way of living is to seek knowledge beyond our comfort zones Tim lives in the United Kingdom with a scruffy dog and a rotating group of daughters, who take turns attempting to look after him He’s still alive, so he reckons they’re doing a pretty good job
