Canadian journalist Jonathan Kaye has written a remarkable book about
conspiracy theories and theorists. The 9/11 Truth movement is placed
front and center, but the book is about a lot more than that, ranging
from a brief history of conspiracism, to a discussion of its causes,
to suggestions about how to combat it.
Very simply, this is a "must read" for anyone interested in or
concerned about conspiracy theories.
