a.k.a. the Baghdad Bob of creationism
Casey Luskin is a lawyer (and not a scientist, although he seems to be a little confused about what such credentials do or don't mean) and one of the primary spokespeople for the Discovery Institute. Mr. Luskin obtained a Bachelor of Science and a Masters Degree in Earth Sciences from the University of California, San Diego, and has as a lawyer published “Intelligent Design Will Survive Kitzmiller v. Dover”, and “Alternative Viewpoints about Biological Origins as Taught in Public Schools” (published in the Journal of Church and State). His work illustrates well the actual goal of the Discovery Institute – to get religion, in the form of intelligent design creationism, into public school curricula (not to do any actual scientific research).
Luskin is by far most notorious for his ability to distort scientific evidence to suggest conclusions completely opposite to what the evidence suggests (and curiously always to fit his preconceived notions of what it ought to show), such as here. An even better example of the distortions and quote mining (to put it mildly) he usually reverts to is perhaps this one (or this one). And if you are feeling particularly sadistic, you can watch Luskin getting completely eviscerated here.
The problem with Luskin and his ilk is that they're ignorant of a topic about which they believe they're experts (see The Dunning-Kruger Effect). Luskin appears to believe he’s an expert with absolute confidence and pride, but to anyone with even a cursory understanding of the fields in question his failings are miserably obvious (see also this). In fact, his misunderstandings of science – and his lack of awareness of his own lack of understanding – often reach epic proportions.
Luskin is also interestingly paranoid, going so far as to claim that published articles on evolution contain “veiled threats” against the creationists and that Nature, for instance, has launched a propaganda war on creationism. Of course, science itself is a threat to creationism; what Luskin fails to grasp is the fact that science is concerned with evidence, not argument and polemics. By failing to see the difference (and furthermore failing to distinguish criticism from personal attacks) he comes to equate scientific evidence against his dogmatic beliefs with personal attacks from the scientists who have discovered the evidence (for more on Luskin’s lack of understanding of how science works, see this).
A good assignment in an introductory critical thinking class is to identify some of the mistakes Luskin makes here (I have used it myself).
Diagnosis: Staggeringly cranky illustration of where Dunning-Kruger, confirmation bias and complete lack of understanding of science can lead you. He is very productive and vociferous, and must be considered rather dangerous to a rationality-based, modern civilization.
