Intelligent Design is a career-killer. There's just no two ways about it. And not because of how peers treat the ID supporter; they throw their own productivity under the bus, to use Casey Luskin's overworked cliche. We saw the same thing with Behe and Dembski. Behe has published ONE peer-reviewed paper in the last decade-ish. And Dembski... well, does anybody even know where he works these days?
All hyperbole aside, let's look at Gonzalez's publication track record while we keep in mind that tenure committees consider work that comes in after one joins the university to be of prime importance. I made a graph of the DI's list of his peer-reviewed publications. Note that I did remove a few articles: one was a review paper published in 2006, as tenure committees generally don't consider review papers to carry much weight, and also 3 papers in 2003 that were clearly reanalyses of old data collected during his postdoctoral years or time at University of Washington (we can tell because it explicitly says "reanalysis" or something similar in the title, and the papers are all published with Gonzalez's old colleagues from those days, plus he isn't even lead author, so the committee likely won't consider them to count much at all towards his work at ISU).
Edit: Lynch made a better graph so I swapped it out.
The purple bars are first-author publications, and the blue bars are minor author publications. The height of the two together in any specific year is the total for that year. Looking at the graph and the DI's list of publications, it's pretty obvious that Gonzalez had a very successful postdoc with a good research group, and that carried over to his first faculty appointment at University of Washington, where he continued to collaborate with his old colleagues from his Ph.D. and postdoc. However, he peaked in 1999, and the decline began even while he was still at the University of Washington. Even more pronounced than the drop in publications is the complete bottom-out in first authorships that is almost sustained throughout his entire probationary period leading up to tenure.
So ISU Physics is stuck with a guy who publishes hardly any papers as primary author, whose publication list contracts once he strikes out on his own, and, perhaps most importantly, who doesn't publish with new colleagues. New tenure-track investigators are expected to integrate into their departments, and to survive in a funding climate as shitty as our current one, investigators HAVE to work together. They absolutely MUST take an active role in pursuing one another's research interests in order to stretch meager funds as far as possible.
Gonzales simply has not done that. And the DI can't complain that Privileged Planet was responsible for his not being a team player; Gonzalez's productivity plummet took place before PP was released. He was already treading water at that point. If anything, his output got slightly better after PP, because he at least put out some first author papers. If an investigator can't collaborate successfully at his or her new institution, he or she needs to network with researchers at other institutions and get papers out, mentor students, and get grants out. Gonzalez already had that network in place, and yet failed to adequately capitalize on it.
As I said before, ID is a career-killer. Not because people shun it scientifically, but because ID is a scientific dead-end. We need look no further than the careers of "prominent ID scholars" to demonstrate that fact. They may crank out excellent science even years after getting tenure, but once they start dabbling in ID pseudoscience productivity goes out the window. Gonzalez is just the latest travesty to add to that list; after being awarded his Templeton Grant for Privileged Planet in 2000**, his research output sunk and never recovered. Gonzalez did this to himself, and I doubt the outcome would have been different at any institution.
**Edit in: I was mistaken. Templeton didn't award him the grant to write Privileged Planet, they gave it to him to gather data. From a letter to The Chronicle:
The grant to Gonzalez was to support scientific research on the dynamical and compositional properties of the sun with respect to other local stars. In Mr. Monastersky's article, Professor Gonzalez made it sound as if in some way the John Templeton Foundation had supported his study of intelligent design. This is not true. The foundation does not support research programs that deny large areas of well-documented scientific knowledge.
Emphasis mine. So even the Templeton Foundation doesn't think ID is science. That speaks volumes.
