Mother Jones Doesn’t Know Data

Wednesday, July 31st, 2013

You know, you could probably cut out a career in responding to Mother Jones twisting and distorting of data from gun deaths. Today has another wonderful example. Hopping on the rather hysterical claim that gun deaths are close to exceeding traffic deaths, they look at it at a state by state level and conclude that “It’s little surprise that many of these states—including Alaska, Arizona, Colorado, Indiana, Utah, and Virginia—are notorious for lax gun laws.”

Look at the map. Then look at this one which shows the Brady Campaign’s scorecard for state laws on guns. The states were gun deaths exceed traffic deaths are Alaska (Bradley score 0), Washington (48), Oregon (38), California (81!!), Nevada (5), Utah (0), Arizona (0), Colorado (15), Missouri (4), Illinois (35), Louisiana (2), Michigan (25), Ohio (7) and Virginia (12). Of the 14 states, half have Brady scores over 12 and California has the most restrictive gun laws in the nation.

Going by rate of gun ownership, the states are Alaska (3rd highest gun ownership rate in nation), Washington (33), Oregon (28), California (44), Nevada (38), Utah (16), Arizona (32), Colorado (36), Missouri (15), Illinois (43), Louisiana (13), Michigan (27), Ohio (37) and Virginia (35). In other words, the states where traffic deaths exceed gun death are just as likely to have a low gun ownership rate as a high one.


Moreover, the entire “guns are killing more than cars” meme is garbage to begin with. Gun deaths, as I have said in every single post on this subject, have fallen over the last twenty years. The thing is that traffic deaths have fallen even faster. The gun grabbers might have had a point back in 1991, when we had a spike in gun deaths that caused them to almost exceed traffic deaths. But they don’t now because both rates are down, way down. Traffic fatalities, in particular, plunged dramatically in the mid-00′s.

A real analysis of the data would look at both factors to see if better drunk driving laws or seatbelt laws or whatever are also playing a factor here. But Mother Jones isn’t interested in that (for the moment). What they are interested in is stoking panic about guns.

(Notice also that MJ illustrates their graph with a picture of an assault rifle, even though these are responsibly for a tiny number of gun deaths.)

The Worst of the Oscars: 1978-2012

Saturday, July 13th, 2013

One of the things that happens from this point forward is that action movies and cult movies begin to take over the IMDB ratings. We also, by the 90′s, begin to run into IMDB’s bias toward recent films. So the comparison of Academy to IMDB becomes steadily less useful.

IMDB’s temporal bias is the result, in my opinion, of fanboys and excited audiences wildly over-rating pictures right when they see them and then not going back to revisit their ratings. There’s a sort of “observer effect” in films since the late 90′s where IMDB itself has become part of the process. So people, in the moment, think “Best. Movie. Ever!” rush over to IMDB and rate it a 10. Five years later, they’d probably rate it an 8.

IMDB ratings have a predictable rhythm. New movies shoot up to the top, sometimes to #1, based on early fanboy ratings and deliberate attempts to raise the rating. Then they slowly sink down to Earth as general audiences catch up. I don’t think they are as bad as critics say nor are as manipulated as snobby websites like to pretend. But they do have issues.

At some point, IMDB is going to have to tweak their formula to downweight votes that were cast (1) for movies that debuted since IMDB was inaugurated, and (2) in the immediate months after a movie was released. I think this would remove a lot of the bias, at least for anything less than ten years old.


Mathematical Malpractice Watch: Et Tu, Reason?

Sunday, June 30th, 2013

Oh, no, not you, Best Magazine on the Planet:

The growth of federal regulations over the past six decades has cut U.S. economic growth by an average of 2 percentage points per year, according to a new study in the Journal of Economic Growth. As a result, the average American household receives about $277,000 less annually than it would have gotten in the absence of six decades of accumulated regulations—a median household income of $330,000 instead of the $53,000 we get now.

You know, I hate it when people play games with numbers and I won’t put up with it from my side. I agree with Reason’s general point that we are over-regulated and badly regulated and that it is hurting our economy. Even the most conservative estimates indicate that bad regulation is sucking hundreds of billions out of the economy — and that’s accounting for the positive effects of regulation.

But the claim that we would be four times richer if it weren’t for regulation is garbage. As Bailey notes in the article, the growth in the US economy over the last half century has been about 3.2 percent. Without regulation, according to this study, it would have been 5.2, which is far higher than the US has ever had over any extended period of time, even before the progressive era. And because that wild over-estimate is exponential, it results in an economy that would be four times what we have now; four times what any large country would have now. The hypothetical US would be as wealthy, relative the real US, as the real US is to Serbia. Does anyone really think that without regulation we would be producing four times as much goods and services?

Even if we assume that we could produce an ideally regulated society, regulation is not the only limit on the economy. Other factors — birth rate, immigration, war, business cycles, education, technological progress, social unrest and the economic success of other countries — play a factor. A perfectly regulated society would most likely move from a position where its growth was limited by regulation to a position where its growth was limited by other factors (assuming this is not already the case)

The paper is very long and complicated so I can’t dissect where their economic model goes wrong. But I will point out that no country in history, including the United States, has ever had half a century of 5% economic growth. Even countries with far less regulation and far more economic freedom than we have do not show the kind of explosive growth they project. In the absence of any real-life example showing that regulatory restraint can produce this kind of growth, we can’t accept numbers that are so ridiculous.

Other studies, as Reason notes, estimate the impact of regulation as being something like 10-20% of our economy. That would require that regulation knock down our economic growth by 0.3% per year, which seems much more reasonable.

(H/T: Maggie McNeill, although she might not like where I went with this one.)

  • Mother Jones Again. Actually Texas State

    Wednesday, May 22nd, 2013

    Mother Jones, not content with having running one of the more bogus studies on mass shootings (for which they boast about winning an award from Ithaca College), is crowing again about a new study out of Texas State. They claim that the study shows that mass shooting are rising, that available guns are the reason and that civilians never stop shootings.

    It’s too bad they didn’t read the paper too carefully. Because it supports none of those conclusions.

  • The Texas State study covers only 84 incidents. Their “trend” is that about half of these incident happened in the last two years of the study. That is, again, an awfully small number to be drawing conclusions from.
  • The data are based on Lexis/Nexus searches. That is not nearly as thorough as James Alan Fox‘s use of FBI crime stats and may measure media coverage more than actual events. They seem to have been reasonably thorough but they confirm their data from … other compilations.
  • Their analysis only covers the years 2000-2010. This conveniently leaves out 2011 (which had few incidents) and the entirety of the 80′s and 90′s, when crime rates were nearly twice what they are now. The word for this is “cherry picking”. Consider what their narrow year range means. If the next decade has fewer incidents, the “trend” becomes a spike. Had you done a similar study covering the years 1990-2000, using MJ’s graph, you would have concluded that mass shootings were rising then. But this would have been followed by five years with very few active shooter events. Look at Mother Jones’ graph again. You can see that mass shootings fell dramatically in the early 2000′s, then spiked up again. That looks like noise in a flat trend over a 30-year baseline. But when you analyze it the way the Blair study does, it looks like a trend. You know what this reminds me of? The bad version of global warming skepticism. Global warming “skeptics” will often show temperature graphs that start in 1998 (an unusually warm year) and go the present to claim that there is no global warming. But if you look at the data for the last century, the long-term trend becomes readily apparent. As James Alan Fox has show, the long-term trend is flat. What Mother Jones has done is jump on a study that really wasn’t intended to look at long-term trends and claim it confirms long-term trends.
  • Mother Jones’ says: “The unprecedented spike in these shootings came during the same four-year period, from 2009-12, that saw a wave of nearly 100 state laws making it easier to obtain, carry, and conceal firearms.” They ignore that the wave of gun law liberalization began in the 90′s, before the time span of this study.
  • MJ also notes that only three of the 84 attacks were stopped by the victims using guns. Ignored in their smugness is that a) that’s three times what Mother Jones earlier claimed over a much longer time baseline; b) the number of incidents stopped by the victims was actually 16. Only three used guns.; c) at least 1/3 of the incident happened in schools, were guns are forbidden.
  • So, yeah. They’re still playing with tiny numbers and tiny ranges of data to draw unsupportable conclusions. To be fair, the authors of the study are a bit more circumspect in their analysis, which is focused on training for law enforcement in dealing with active shooter situations. But Mother Jones never feels under any compulsion to question their conclusions.

    (H/T: Christopher Mason)

    Update: You might wonder why I’m on about this subject. The reason is that I think almost any analysis of mass shootings is deliberately misleading. Over the last twenty years, gun homicides have declined 40% (PDF) and gun violence by 70%. This is the real data. This is what we should be paying attention to. By diverting our attention to these horrific mass killings, Mother Jones and their ilk are focusing on about one one thousandth of the problem of gun violence because that’s the only way they can make it seem that we are in imminent danger.

    The thing is, Mother Jones does acknowledge the decline in violence in other contexts, such as claiming that the crackdown on lead has been responsible for the decline in violence. So when it suits them, they’ll freely acknowledge that violent crime has plunged. But when it comes to gun control, they pick a tiny sliver of gun violence to try to pretend that it’s not. And the tell, as I noted before, is that in their gun-control articles, they do not acknowledge the overall decline of violence.

    Using a fact when it suits your purposes and ignoring it when it doesn’t is pretty much the definition of hackery.

    It’s been a while and I’ve been accumulating links. You’ll have to forgive me if I ramble on a bit.

  • This article, about the potential for solar-powered roads, reminded me of Robert Heinlein’s The Roads Must Roll. But I am deeply skeptical that the kind of durable materials could be manufactured in the quantities needed.

  • See, I told you Christopher Ryan was full of shit. He writes about our bleak future with sexbots taking over (or something). But Maggie McNeill — who knows a thing or two about sex — has frequently pointed out that people want intimacy for sex, not just pleasure. And a device capable of reproducing that would have rights of its own. Masturbation doesn’t cut down on the amount of sex people have. And I also haven’t noticed that the proliferation of dildos, vibrators and fleshlights has remotely cut down on the amount of sex going on (and reminder, dildos date back thousands of years). We have sex for intimacy as well as pleasure.
  • An impressive study reveals the age of the Iliad. Seems it was written about four or five centuries after the events.
  • This study disputes the idea that people’s political preferences change with age. You can clearly see that Democratic/Republic preferences are often based on who was in charge when the voter came of age. This doesn’t surprise me at all. As you can see in the graphs, Roosevelt, Kennedy, Reagan, Ford, Bush I, Clinton, Obama and Ike were respected and made lifelong supporters. Truman, Johnson, Carter, Nixon, and Bush II were hated and made lifelong opponents. I knew teachers who would never vote Republican because of Nixon. And I know people who will never vote Democrat because of Carter. It will be interesting to see how history judges Obama. I suspect he will create more lifelong supporters than opponents.
  • The opposition to GMO’s grows ever more absurd. We now have a golden rice that could literally save millions per year. And the opposition to them is increasingly based on lies and distortions.
  • As I Predicted: EMR

    Friday, February 22nd, 2013

    I thought I’d put these three links into a separate post. Long ago, when electronic medical records were being cited as the way we could save money in our healthcare system, I was skeptical. I pointed out that these innovations might save lives and might make things easier on patients. But they were unlikely to save money. I based that on my dad’s experience with EMR, in which he found them to be very expensive, amazingly disorganized and somewhat bewildered by HIPPA requirements.

    Well, I was right. Here you can read about how EMR’s have encourage the use of boilerplate descriptions which leave critical information out of patient’s record. Here you can read about how it makes doctoring difficult. I’ve experience this personally, finding that doctors spend all their time screwing around with the EMR system rather than interacting with me (although this has improved in the last couple of years as doctors learn from their mistakes and save EMR maintenance until after the appointment). And here you can read about how the system are not saving money and don’t interact with each other.

    Some of these problems will eventually be solved. I expect that a uniform standard will eventually be created (probably by law). Improvements in computer transcription will probably restore dictation over boilerplate for making notes. And, as I noted, doctors are quickly improving their ability to use EMR without sabotaging their interaction with the patient. In the long run, I think this will improve healthcare.

    But easy-to-use systems that have a uniform standard, protect patient privacy and can correctly spell esophagogastroduodenoscopy (as I just did on the first try) are not cheap and are never going to be. This is not the solution to our healthcare woes. There is no silver bullet that is.

  • Mother Jones Hacks Again

    Monday, February 18th, 2013

    A few weeks ago Mother Jones, having not learned the lesson of their absurd article claiming mass shootings are on the rise, published a list of 10 Myths about guns and gun control from Dave Gilson. And I’m going to debunk their debunking again because the article represents what I believe is one of the worst sins in the field of Mathematical Malpractice: cherry-picking. As I went through this, it became obvious that MJ was not interested in the facts, really. What was motivating them was the argument. And so they picked any study — no matter how small, how biased or how old — to support their point. They frequently ignore obvious objections and biases. And they sometimes ignore larger more detailed studies in favor of the smaller ones if it will support their contention.

    We see this a lot in the punditocracy, unfortunately. As Bill James said, most people use studies the way a drunk uses a lamppost — for support, not illumination. In any sufficiently advanced but difficult field of study, you will find multiple studies examining an issue. Let’s say it’s a supposed connection between watching Glee and having a heart attack. If there is, in reality, no connection between the two, you might find eight studies that show no connection, one that shows an anti-correlation and one that shows a correlation. This is fine. This is science. There are always outlier studies even if all the researchers are completely ethical and honest. The outliers fall away when your interest is the question and you look at all the evidence. But the outliers dominate the discussion from those who have an agenda.

    This happens a lot in the gun debate. On both sides, really. But Mother Jones’ article is a particularly putrid example of this because that’s basically all it does: collect the cherry-picked nonsensical studies that support their anti-gun agenda. It’s quite remarkable actually; almost a clinic in how not to do research.

    But here’s the one thing that really tips you off. There is one myth that Mother Jones does not debunk. It’s a myth that’s really independent of what you think of gun ownership … unless you’ve already staked part of your reputation and agenda on the myth that gun violence is increasing. In fact, all forms of violent crime have been falling for twenty years. This is, in my mind, the single most important fact in debates over crime and violence and the single most important myth to debunk.

    MJ does not address this myth. They don’t even talk about it. That is a huge tell.


    Looking Ahead to 2013

    Wednesday, January 2nd, 2013

    Any year you can walk away from is a good one right? I ended 2012 with my family and career intact, so I don’t think I can complain too much. Abby had a great year with her first real birthday party and a good start to kindergarten. I landed a couple of grants and got a couple of big projects off my plate, including the image gallery for the mission.

    On the other hand, I had my gallbladder out and had a sudden awful onset of bad migraines, something I still have not quite gotten control of. My mother-in-law died. My stepmother got cancer. We spent a fortune on fertility treatments and got, for all our pains, one miscarriage and a bad MS relapse. So … yeah, not our best year.

    In sports, my Braves bowed out in ignominious fashion and the hated New York Giants stomped over the Falcons, Packers and Patriots. On the other hand, the Falcons had another good regular season, the Braves have a lot of young talent and Chipper Jones went out in grand fashion.

    Politics? Oh, God. This was one of the most frustrating disillusioning years I can remember. I looked at both parties and eventually slammed my head into the desk and voted for Gary Johnson. We had a huge amount of sound and fury. More digital ink was spilled than ever before. I blogged my guts out over at Right Thinking. And the result? Obama is still President, Congress is still split, Congress is still stupid, the deficit is still huge and the economy is still sluggish.

    But, for some strange reason, I have a good feeling about 2013. 2011 was a the year of false hope — personally, professionally and politically. 2012 was a tough grinding exhausting year. But I feel like things have put in motion that will make 2013 suck a lot less. I can’t put my finger on anything specific. That probably means I’m wrong.

    Oh, well. Without further ado, my bold predictions for 2013:

  • Alabama over Notre Dame; New England over Green Bay; Miami in the NBA, Cincinnati over the Angels
  • Movies look like a mixed bag. Bad remakes and sequels galore (Evil Dead, GI Joe 2, Hangover 3, Die Hard 5, etc.). Beautiful Creatures and Pacific Rim look hilariously bad. And I’m not optimistic about Oz, Man of Steel or The Great Gatsby even though I want to be. I’m worried Hobbit 2 will suffer from Middle Chapter Syndrome (even more than Hobbit 1 does). But maybe something will surprise us.
  • We’re going to have a debt ceiling crisis that will hurt the economy and result in almost no spending cuts of note. Nevertheless, the economy will lumber on. And, for the first time in years, the deficit will notably shrink.
  • The Supreme Court will have another interesting year, likely striking down Prop 8 but on very narrow grounds.
  • Japan and China will rattle sabers but no fighting will break out. We will probably eventually intervene in Syria. The EU will continue to lumber toward a unified state.
  • So, yeah. Even looking at that, I’m not predicting a great year. But 2012 was so lousy, 2013 is almost bound to be better.

    We must always remember that the arc of history is long and, over the last decade, has pointed toward progress. On a global level, things are improving. Steadily, haltingly, frustratingly. But improving. And maybe 2013 will be the year things start improving around here — slowly, haltingly, frustratingly. In the end, the future is what we create. And I intend to bend my shoulder a little bit more this year and push a little harder.

  • Mathematical Malpractice: Spree Killings Again

    Monday, December 17th, 2012

    This analysis, which claims that the US has more school spree killings than 36 nations combined, is getting a lot of play. It shouldn’t. It is extremely bad mathematical malpractice.

    The basic reason it is mathematical malpractice is the same reason the Mother Jones study was: it is difficult to analyze extremely rare events. When you narrow your investigation to events that happen maybe once a decade and are compiled haphazardly, you are simply going to be dominated by small number statistics and selection bias. You can therefore use those numbers to say, basically, anything you want.

    Let’s break down just how bad the numbers are being twisted here.

    1) The sample ends in 2009. That excludes the recent spate of knife attacks in Chinese schools that have left 21 dead. If you did this analysis a week ago, you would have had to drop China from the right column.

    2) The sample excludes acts of terror or war. But if Islamists shoot up a school because they don’t want girls to read, are those kids any less dead? If a drone strike misses its targets and kills a classroom, are those kids less dead? Why must we exclude the Beslan attack that left 186 kids dead?

    3) The sample excludes single homicides, which amount to 302 deaths in the United States over the time involved and God knows how many in other countries. So you are literally excluding 90% of the problem and focusing just on a tiny subset of killings.

    4) Comparing us to 36 other countries is ridiculous when some of those countries are places like Bosnia-Herzegovina (population 4 million). We have more population, period, then 30 of the countries on that list combined. Also included in that list of countries are England, Scotland and Northern Ireland, which are, technically speaking, not countries.

    5) The problem of small number statistics can be best illustrated by playing with the data a bit. If I include the knife attacks and move China into the left column, suddenly China has more violent deaths than 30 other countries. If I move Germany onto the left side, suddenly they have more spree killings than a bunch of other countries. If I define the sample in the 1990′s, suddenly Australia dominates the statistics. You simple can not draw conclusions from samples that are that sensitive to single events.

    6) Combining points 4 and 5, if you look at spree killing rates rather than the deliberate mathematical malpractice of comparing absolute numbers, the situation is very different. In 2009, the Winnenden shooting killed 15. Scaled up to the population of the United States, that would be the equivalent of 60 people dead, more than the worst year the United States has ever had. In 1996, 35 people were kill in Port Arthur, Australia. Scaled up to the US population, that would almost equal 500 dead. It is an event that is seared into the memories of Australians. My point is not that these countries are worse than we are. My point is that these are rare and horrible events and you can manipulate the numbers to prove anything you want.

    7) The biggest thing missing here is a sense of time. Is the rate of school killings going up or down? The answer, of course, is down. Check out chart one at Ezra Klein’s blog that shows that the rate of assault death has fallen by over half since 1970. Check out the NCES page I link above which shows a significant decline in on-campus homicides, from 40/year in the 90′s to 30/year in the 00′s. That decline is a hundred more kids running in the sunshine. The NCES data, based on a complete sample of over 600 incidents, is useful. This …. isn’t.

    I’m not trying to downplay the horror that unfolded on Friday. However, I don’t think any debate can proceed unless we have a good grasp of the problem we are trying to solve. Far too many children are murdered in school in this country — that was as true on Thursday as it is today. But to be useful, the debate needs to be on honest terms. Committing mathematical malpractrice by deceptively comparing the United States to 36 other countries as though there something to be learned from that is not an honest debate and is likely to produce a panicky and ill-considered response.

  • The idea of building gondolas in Austin strikes me as a really dumb. Gondols are slow and would take up lots of space for the number of passengers they transport. Texans aren’t big on mass transit to begin with (the light rail system is likely to be a flop). And what do you need a gondola for in a city that is really flat? This crosses me as a solution in search of a problem. And if it doesn’t have high ridership, it’s bad for the environment. And expensive.
  • Down with homework!
  • I always suspected that the high I got off parenting was an evolutionary thing. I find these things intriguing and fascinating. Much of what we feel in life: compassion, empathy, love, tenderness is the result of millions of years of evolution making us into creatures that look for the species rather than ourselves.
  • A really good post on the Jefferson slave thing. Also, highly recommended on the subject: Ta-Nehisi Coates. Actually, TNC is just recommended, full stop.
  • One day, parenting authorities will get it through thick skulls like that fun physical activities are good for children even when they involve a low amount of risk.
  • Ah, peak oil. These days, the biggest energy concern is that we won’t run out of fossil fuels and that global warming will be worse than feared.
  • A fascinating story from NPR about how our image of Jesus has changed with social norms.
  • While it strikes me that global helium supplies are a legitimate concern, the idea that our technical needs in 50 years will be the same as they are now crosses me as silly. Think about the chemicals that were important 50 years ago. Are we in the grips of a global lead shortage?
