The State of Science Education

Spotting-Bad-Science-v2.pngI’m not sure how I came to be reading this article, especially strange because the byline states that it was published over a year ago in The American Spectator. I expect it was mindlessly following some click-bait on Yahoo that brought me there, but what I found was the tragic remnants of a mind denied a proper education in scientific method, logic, and mathematics.

Emily Zanotti wrote up her impressions of a scientific study she had uncovered in an article titled, “Study Finds John Kerry Worst Secretary of State in the History of Ever. John Hayward wrote a similar piece for Breitbart the same day, as did the Washington Post, under the slightly less scathing headline, “Scholars votes put Kerry last in terms of effectiveness.” So, why focus on this minor publication’s reporting over more mainstream outlets? I don’t have much reason other than the fact that I found the article there first and the visceral nature of the title held my attention best (remember, I found it by following click-bait while trying to find a reasonable source of right wing news).

I really don’t care (at least for the purposes of this discussion) one bit about the actual question, but would rather focus on how these data were interpreted for the popular press (using Ms. Zanotti’s article as my example).

First, the data:

The articles I found pointed to Foreign Policy Magazine as the source, the actual data in the rawest form I could find can be found here.

Who was polled? (because this is an opinion survey):The poll was sent to International Relations (IR) faculty from colleges and universities around the country. Responses were received from 1,615 IR scholars drawn from 1,375 U.S. institutions.

The question about Secretaries of State was one of many, and was phrased as, “Who was the most effective U.S. Secretary of State in the past 50 years? ” We’re told that the number of responses to this particular question was 655. I think it’s rather strange that only half of the respondents answered this question, especially given that one of the most popular answers was ‘I don’t know’ receiving 18.32% of the vote, or 120 ballots.

The Results were reported as:

only 12 are people if we drop out the ‘I don’t know’..
This is interesting because the headline read that Kerry was the worst

I agree that he is last on this list, but depending on how you want to count, the number of people who sat in that office for the past 50 years was either 15 actual Secretaries of State or 28 Secretaries + acting Secretaries.

Either way you slice it, we’re missing some people from this list. A quick look at trusty Wikipedia show us who we’re missing (See below). Where is Will Rogers in the poll? Edmund Muskie? Apparently these poor souls got zero votes, so they don’t show up in a percentage-based calculation.

At 0.31%, poor John Kerry received only 2 votes as the most effective Secretary of State (SoS) in the past 50 years. But Rogers and Muskie apparently got zero. It’s hard to see that this puts Kerry in last place.

But that’s not all. The question asks, “who was the most effective SoS?” which isn’t the same as asking respondents to “rank the SoSs according to effectiveness.” What would the percentages look like if two Secretaries (say, Bob and Hank) were the clear front-runners and everyone agreed on that point? Moreover, imagine that everyone also agreed that a third Secretary(Sally) clearly came in right behind the two front runners, but couldn’t compare to the undeniable efficacy of the first two. My guess would be that Bob and Hank would split the 655 votes, and no one else would get any. Not even Sally. Everyone else ties for last place.

Ms. Zanotti’s piece continues, “John Kerry is the worst Secretary of State in history according to a survey of professors at the top 25 foreign policy schools conducted by Foreign Policy Magazine, losing out, even, to ‘Don’t Know.'”

bad_science1.jpgBut no one was asked to name the worst SoS. What is true of this survey is that very few people think Kerry is the best. As for ‘Don’t know’, I imagine that these are the people who simply can’t decide between Bob and Hank, from the example above. Those two are just too close to call. Further, since ‘Don’t know’ came in second, it’s hard to say that Kerry was beaten by this answer in any meaningful way.

She continues, “Of the scholars who responded, Kerry earned exactly two votes, and came in after Lawrence Engleberger who was Secretary of State for a whole six weeks at the end of George H. W. Bush’s second term, and spent most of that time keeping the chair warm for the Clinton appointee.Which had me wondering if perhaps one of the best ways to be an effective SoS is to not have much happen, as is the case when someone is in office for only a very short time.

One last statement on the data before going to her conclusion… In reporting the results of the poll, she mentions that, “James Baker — who was actually the most effective secretary in the last 50 years” came in third at 17.7%. Wait – what? Where is this “who was actually the most effective secretary” come from? Was there another measure that we haven’t been provided with? My guess is there was not, but that this is the author’s admission that she has already determined the right answer and that no data applies to this opinion.

Ms. Zanotti then ends her essay with this strange statement, “At any rate, it’s nice to know our collective impression of Kerry’s effectiveness is objectively verified. ”

I guess she knows her audience, so the “our collective impression” probably makes sense saying, but what about the idea that Kerry’s effectiveness has now been objectively verified?

What about an opinion poll could ever result in an objective verification? I suppose she might mean that it is now verified that many people hold some opinion, but it’s hardly objective. To arrive at this conclusion, we have to accept that the sum of many (at least 655) subjective opinions is equal to an objective conclusion.

This is equivalent to saying that a poll of 400 Yahoos objectively verifies that the sum of 2 and 2 is 8. All we have is a group of opinions. They might be the opinions of very smart people who are speaking within their field, but there’s no logical necessity that they are correct.

So, to return to my title. I can only assume that this hot mess of an essay comes from a completely science deprived education. Who is the author, Emily Zanotti? I had never heard of her and had her pegged for a one-off writer who wasn’t really involved in the world, but I stand corrected. She’s apparently well known amongst the Right as an outspoken libertarian. Her twitter bio reads, “Writer, blogger, comedian, nerd. Cosplayer. Catholic. Political reporter. Resident geek . Libertarian. Opinions my own but should be yours.” Her R Street bio calls her, “a columnist for the The American Spectator  and an associate fellow of the R Street Institute. She is a ten-year veteran of political communications and online journalism based out of Chicago, where she runs her own digital media firm. Her work has appeared at her former blog, NakedDC, and across the web. She has a law degree from Ave Maria School of Law with a focus in intellectual property and technology law” (Sic).

I’d never heard of the Ave Maria School of law, so I had to look that up too. The Miami New Times  had this to say about the school:

Meanwhile, Ave Maria — founded by Domino’s Pizza magnate Tom Monaghan and relocated in 2009 from Ann Arbor, Michigan — continues to plummet, finishing dead last with a horrific 47.8 percent of students passing the [Florida Bar Exam].

However, this poor performance is apparently relatively new, with  former Ave Maria law professor, Charles Rice, stating in the same article that the school’s performance was good prior to the move. Together, these statements make it difficult to use the school as any proxy assessment of the person’s education. Regardless, her R Street bio suggests that she’s not a fool. Therefore, I’m left wondering… how did this article happen?

Your Inner Fish – Chapter 1

tiktaalik_reconstructionThis semester, like the preceding three or four semesters, my general biology class is reading ‘Your Inner Fish’ by Neil Shubin. Every week, we cover one chapter and my students write an essay with their thoughts before we discuss that chapter in class.

Last week was our first week with this book, so I’ve just completed reading several essays on chapter 1 from my students. Overall, I’d say that the book seems to be getting a good response and at least interests most people. I’ve had a wide variety of responses with respect to accepting the author’s interpretations of Tiktaalik, his find of a ~375 million year old fossil species that shows evidence of being a transition species for the first quadrupeds to come onto land.

This is always a fun group of essays for me to read because it challenges students to consider their perception of science as a way of viewing the world. Or, perhaps I should say, ‘science, as a way of understanding the world around us.’ A scientific view of the world is actually a fairly unnatural one. It is easy to see how it is even evolutionarily disadvantageous to have a scientific view of the world. If you have been a victim of a crime (you imagesget mugged walking down a city street) don’t you always expect that crime to happen again? It doesn’t matter that this happened only once out of thousands of times you walked the same route home, you now feel convinced that this is dangerous and are more alert and cautious. You may even find a new way home. And who would blame you? We’re programmed to look out for our own safety. This often means over-exaggerating  our fears and assuming the worst. It also means that we will now overestimate the real danger.

The other thing this discussion brings up is: what does science do for us?

The answer is supposed to be, ‘it enables us to learn from the past and have a better ability to predict the future.’  We can make predictions about things if we closely observe the world and learn its laws. The corollary to this is, if you can’t learn from the evidence you see about you, how can you ever know what to expect from the world?

All of these are interesting questions. All of them challenge how we look at the world, what we take for granted and what we can expect to get from our experiences. I’m really looking forward to reading more of my students’ reflections on this text and hope that you (anyone reading this) feel free to engage in a dialog about either this book, or the questions it brings up.

The nature of truth

Image

The Valley of the Shadow of Death

There was an interesting podcast by RadioLab this week concerning the nature of truth that I wanted to comment on. There were a number of stories in the broadcast, as always. One on yellow rain is getting the lion’s share of attention on the RadioLab site for the treatment of one of the guests that many listeners objected to. However, that is not the one I would like to focus on. In fact, I really only wanted to mention the podcast because I thought it was a good introduction to a topic that I find troubles a lot of people.

First, the podcast. I would point you towards the short, “In the valley of the shadow of doubt,” about one of the earliest photographs taken during wartime. In fact, the episode is about two photographs by the same person, Errol Morris, who was documenting the Crimean War in 1855. The two photographs depict the same scene, titled ‘In the Valley of the Shadow of Death’ that depict a road in the Ukraine. In one, the road is littered with cannonballs. In the other, there are no cannonballs on the road, but there are many off on the side of the road in ditches an on the hills.

The question that the photographs bring up is, ‘Which one was taken first?’ That is, did the photographer come upon a road littered with cannonballs that were removed – or did he come across a road surrounded by cannonballs that he moved in order to catch a more interesting shot?

Of course, we can never know.

There are reasons that can lead us to believe one thing or another (personally, I think one argument is stronger) but there is no way to know absolutely one way or the other. This is the real question that the episode brings up, “Can we ever know truth?” This is a very basic question in science. Most scientists agree (I am presuming) that we can never know anything with certainty. We can only rule out unlikely answers and give support to one theory or another.

Wielder of Occam’s Razor

We can blame Descartes for starting this with his Discourses on the Method published in 1637. He started the trouble by giving us the scientific method, a method for uncovering the way the world worked. In his pursuit of this, he also realized that we cannot really know anything. He admitted only one thing that we are sure of. Cogito ergo Sum. But from this modest beginning, he also built up a structure and assured us that we have to assume that we can trust in at least logic, and that, until there was reason to believe otherwise, we may as well proceed as if the world we see around us does exist – evidence that he read his William of Occam (1288-1348).

Natural Philosophers and scientists have been fairly comfortable with this state of affairs for years. Assume that the theory with the most data supporting it is true up until the point that new data demands a change in thinking. At this point, we are instructed to drop the old idea and embrace the new one until it inevitably is displaced.

But these words mean different things to different readers. Some may read this as, “See, they admit it, they know nothing. And even worse, the are certain that their ideas will be proven wrong sometime in the future.” Others think, “Yes, of course. How else could one perceive the world?” And they’re both right – in a manner of speaking. It is assumed that much of what we know will change over time. But we also have the security of knowing that our understanding of the world is getting better all the time and it is unlikely that with new ideas we will entirely abandon out old ways of thinking. Rather, we expect to tweak this ideas.

And this would all be fine. But there is another school of thought that comes mostly from the journalists. That is the idea that every position / point of view is equally valid. There are a lot of questions that come to mind where I do think opposing ideas have equal value. These are political questions mostly. However, when journalists come to interview scientists about some finding or idea, two (or more) sides often don’t have the same weight of evidence behind them.

…hungry……

If I were to ask you where teeth go after they fall out and are placed under a pillow, you might say, “The parents take them and give the children money.” You might say, “the tooth fairy comes and leaves the money in exchange for the teeth.” I tell my son that the tooth fairy needs teeth because she eats them and couldn’t survive without nourishment.

Not all of these hypotheses are equally likely. I have to admit that I’ve never seen the tooth fairy, but someone must have left a camera out to get this picture…

Back to RadioLab. So, what’s true? Does the weight of evidence make something true? Does it make it more likely to be true? Does evidence mean nothing?

On a deep level, perhaps we never know anything. But I can also say this: data is nature’s voice and sometimes it pays to listen.
