Welcome to the Insights course website. It cannot be found by googling; the link is only visible to those who have been given the link. Some of the material is copyrighted, and I have made it available under the "educational use" clause. In addition, this represents a considerable body of research on my part. So please do not share the links to the website with anyone outside the class. Thanks.
