Christopher D. Green, a professor of psychology and philosophy at York University and president of the Society for the History of Psychology, has a strong post on the reasons academics are often turned off by Wikipedia. In the wake of my recent call to Wikipedia arms in the History of Science Society Newsletter, Green looks back on the development of the history of psychology article in the period since he expanded it by about 6,000 words (in the middle of 2007). I have a short reply on Green’s blog.
