This is a really nice use of Wikipedia to create a useful learning resource. The subject is cognitive bas and the author's intent is to bring together and categorize the various sources of bias, then provide some simple heuristics to comprehend them. Great idea (and I not in passing that these biases apply everywhere, and are not subject specific). The article offers an object lesson in how to use open educational resources in such a way that the licenses don't matter. It's the age of the internet - you don't need to mix and combine resources, you just link to them.
