Quicken Loans has managed to cause quite a stir with their Super Bowl ad marketing their new app, the Rocket Mortgage.
The commercial touts the reasons why homeownership advocates support increased homeownership. The justification that housing leads to a stronger economy squares with both conservative justifications for a market economy and progressive efforts to increase homeownership for poor and racial minority households. One can argue about the wisdom of making this reasoning explicit as a marketing strategy; but, the ad makes explicit what lots of people already think (part of me wonders if the ad wasn’t aimed at consumers as much as preempting policymakers who might want to regulate interstate products like Rocket Mortgage).
Unsurprisingly, critics pounced on the idea that a smartphone app foretells the return of the housing crisis. I think that they might be right, but for the wrong reasons.

The Washington Post has been tracking police killings across the nation. Last week, Peter Aldhous published an analysis of these data. He figured that blacks suspects were 37.8% of all unarmed suspects killed by police. White suspects made up a nearly similar percentage of unarmed suspects killed by police, despite the fact that there are almost five times as many whites in the United States as blacks.
This does not provide the best evidence to adjudicate racial disparities in police violence, however. Aldous writes:
Video of McDonald’s last moments, shot 16 times by a white officer, made a stark contrast with images of a handcuffed Robert Lewis Dear, the white suspect in the shooting at a Planned Parenthood clinic in Colorado Springs — as activists were quick to point out.
Rather than figure out the probability that an unarmed suspect was black, it would be important to know the probability that a black suspect
shotkilled by police was unarmed. We care less whether an unarmed victim was black as we do whether a black victim was unarmed. That would be more in line with, though not exactly equivalent to, what Aldhous wrote.
Below, I try to explain how we can use rules of probability to explain this problem to an introductory statistics class. Continue reading “racial disparities in police killings using bayes theorem”
The ongoing scuffles over reproducible (or is it replicable? or robust?) research always seems to miss one point particularly important to my own work: protecting geographic identities of respondents.
I do not wish to argue that we should not replicate or share data. Rather, I wish to suggest that the costs of data sharing are not as low as many make them out to be and that a one-size-fits all policy on reproducible research seems unwise.

Of all of the issues brought up by the Lacour controversy, we have not devoted enough attention to one in my view. The
YaleColumbia* IRB made itself part of this problem.
In his initial comments to Retraction Watch, Lacour’s coauthor and Columbia political science professor Donal Green wrote,
Given that I did not have IRB approval for the study from my home institution, I took care not to analyze any primary data – the datafiles that I analyzed were the same replication datasets that Michael LaCour posted to his website. Looking back, the failure to verify the original Qualtrics data was a serious mistake.
This points to a real cost imposed by intransigent IRBs that become significant hurdles for research to progress. As institutions evaluate their response to this affair, and we reevaluate our own approaches to collaboration, those efforts would not be complete without considering the fact that IRBs hinder good, ethical research.

The Evil EmpireOrgTheory, Fabio makes a case that, as a default, dissertations should take the form of three-paper (or, more generally N-paper) format. On the whole, I totally agree and think that the three-paper format helped me finish grad school and set me up well for my post-doc and life on tenure track.
But the conversation on three-paper dissertations (or, equivalently, “digital” dissertations in the humanities) often fails to address a major shortcoming of the three-paper format. The introduction and conclusion end up being anachronous appendages that weary students tack on at the end. Or, I should say, that a single particular weary student tacked on at the end of his dissertation.
It was not until I had a faculty position and read cover letters as part of the faculty search committee that I realized how I had screwed myself by tacking on an intro and conclusion. In my own letter I had failed to articulate what my research as a whole meant to the discipline and how I charted my own course for research. I had three pretty interesting empirical results and I dutifully described those. What I was missing, I realized, what a broader statement of overall relevance.
I believe that the three-article dissertation contributed to that lack of awareness. It affected my own cover letter and, I think, prevented me from getting more interviews. It didn’t deal a fatal blow to my career, after all I ended up in a great job. But it did limit my options when I entered the job market. In fact, I didn’t write a really cohesive research statement until I wrote my third-year review since that was the first time circumstances forced me, in a relatively concise way, to explain my contribution to the field.
As with any N of 1, especially with the measurement error that occurs when N=me, too many degrees of variables affect an outcome to certainly argue for a particular cause. And I believe that writing three articles established a direct, clear path of publications that helped me secure my post-doc and job that I now have. As with any benefit comes costs, and the three-article dissertation can come at the cost of thinking about larger research narratives. For that reason, I would caution advisors and advise grad students to think early in their candidacy about the larger narrative they construct with the three articles.
I am shocked, stunned, and maddened at the fact that Eric Gardner’s murderer will not even be prosecuted for a crime that was caught on camera. I am also deeply worried about the power of the state in a society where the message to police officers becomes anything that happens on the job will not be prosecuted under the law. You might lose your badge, you might lose your job, but we — as a society — will legally condone whatever you do.
I am not a person to typically denounce the tyranny of the state. In fact, I tend to believe that most problems can be addressed by state action. But this is a systemic flaw that must be addressed. If it doesn’t, it not only hurts those affected by police violence, but it sows mistrust in police and leads people to back non-state actors with their own incentives. Paramilitary violence will further escalate the situation if officers of the law are not held to account.
I am struggling with how to talk with my students today about all of this. It is our last class meeting and I had planned for the last day to be a working day for their final assignment. Apropos of the conversation on policy and agency, I feel like this needs to be addressed. I need to provide them with some way to see how they fit in this picture. Any ideas would be most welcomed.

Since I have found tiny tidbits from the blogs to be helpful over the years, I thought that I would pass along one myself that has been helpful in my life as a professor (it is still weird writing that statement): consider using online booking for office hours. I have seen two benefits from doing this. First, I can see when students are coming and, in the infrequent but not unusual situation of finding common meeting times with colleagues for committee-type meetings, I feel more free to agree to meet during office hours when I can see that no students are signed up to meet. Second, it helps the students since they do not have to wait outside the office until I finish with another student. They can sign up for a time and I can meet with them at that time.
I had used Google Appointment Slots but, alas, like Reader, Google killed them. Now I use the website youcanbook.me to schedule my appointments. You can link it to your Google Calendar and in doing so, it has a pretty slick feature that you can designate a type of meeting in your Google Calendar that youcanbook.me will look for to designate your availability (mine is, appropriately enough, “Office Hours”).
It’s worked for me and it might be worth a try.
