Seth Roberts has written a review of Hiding the Decline at his blog:
Hiding the Decline is as well-written as a book by a professional writer but this is a book no professional science writer could write due to its investment in an officially-wrong point of view. There are lots of badly-written books from tiny-minority points of view. The appearance of a well-written one, joining Montford’s earlier The Hockey Stick Illusion, is no small deal. How much free speech do we have? It depends on the medium. Maybe the sequence from less to more censored is: 1. Conversation. 2. Email and other private writing. 3. Blog post. 4. Poorly-written book. 5. Article in minor magazine. 6. Well-written book. 7. Article in prestigious magazine. 8. Textbook. From one step to the next (e.g., from conversation to email), views become less diverse. This book is disagreement with the official line high up the tree.
