Phineas and Ferb, Climate Change and Language Barriers



I recently read an article on climate change that made me laugh. Not because it was particularly funny, but because it was about the language discrepancy between the scientific community and the lay person. In this article they attributed the general population's reluctance to believe in climate change to the lack of concrete language used by the researchers. They urged these experts to use more black and white statements and "regular" language. This is the point where I laughed.

Because here's the thing. We just can't do it! When I went to write this blog post I looked for the original article I read but couldn't find it. I did however find a great article here and I love this portion of it:

"Scientists are often compelled by their education to tell you more about what isn't known than what is known. That intellectual and academic honesty allows critics to use the scientists' own honesty as a brickbat to pummel their work. As an example, for the past 20 years when reporters would call and ask whether this flood, or hurricane or that tornado was due to global warming, the entire scientific community studying the effects of increased CO2 in the atmosphere would say, "No single event can be attributed to global warming." That is the truth, and climate change skeptics will use that honesty to say, "See, there's no detectible change." "

As a scientist myself I understand this dilema. The more you study science the more variables you discover and you start getting in to the, well that depends on what the definition of "is" is! And it's true. Define your terms is a common phrase in the scientific community. What do you mean by "change?" It's a valid question to the scientific community and unfortunately the lay comunity just thinks you're being difficult or avoiding the truth, when another scientist would simply define their terms and move on.

So why am I talking about climate change on a forensic blog? Because this language barrier exists every time you take the stand. Not only do we have the barrier between ourselves and the jury, but then you have to throw in lawyers and hoo boy, now you have a third language!

I'm reminded of an episode of my son's favorite show. In Phineas and Ferb, the spy bosses give Perry the platapus a robot, but then tell him that the manual is only in Dutch. Unfortunately they don't have a Dutch to English dictionary, but they do have a Dutch to French Dictionary and a French to English Dictionary. So Perry has to use both dictionaries to figure out how to control the robot.

That's like being an expert witness. You have to translate the attorneys question from legalese into science speak and then translate your science speak into layman's terms for the jury. Here's the problem. There are no dictionaries. When you gain familiarity to the legal community you get to the point where you know what they mean to ask even if that's not quite where they're asking, and over time you begin to answer what they mean to ask as opposed to what they actually asked.

Now, what do I mean by this? In breath testing for example an attorney may ask you "Is this test accurate?" I have always hated this question. Why? Because all the attorney wants to know is, is this test right or wrong. To me, my science side starts piping up and yelling in the background what do you mean by "accurate?" To what degree? And accurate of what? Of what the instrument saw or the body burden of the individual?

To answer that question I would state what I was relying upon and then answer whether the test result met the accuracy requirments as by Rule for what the instrument saw in the breath chamber. Is that what the attorneys were always asking? No, probably not.

And the reason I say that it is probably not is because I often run into attorneys who don't understand how two different test results could both be "accurate." Well, define your terms. What do you mean by accurate? When a scientist answers that question they're going to answer whether they were within the accuracy limits required (10% in Vermont for breath alcohol testing) for what was in the instrument at the time the sample was analyzed. If that isn't what the attorney wants to know then they need to change the question.

Although scientists are often aware that there is a language barrier I find that attorneys are often baffled by it. I have often sat on the stand arguing what appears to be minutea to the attorney but what matters quite a bit to me. It's furstrating because although I may know what they mean by their question I simply can not answer it if the terms are inaccurate.

And this is why the urge to researchers to change their dialogue when speaking about their research is doomed to fail. They are still scientists and they must first and foremost be repsected in that community. A person who speaks in blacks and whites and absolutes is not a scientist and will not be taken seriously by that community. That's not how research works. The scientific process will always be to form a hypothesis and then try to disprove it. The answers will always be that the evidence thus far indicates or research suports x, y and z. It will never be x causes z. It will never be in absolutes.

In order to be effective in the courtroom, expert witnesses need to be able to bridge the language barriers without compromising their scientific integrity. It's a difficult balance because you often do fall into answering what is meant by the question as opposed to what is asked. That is why it is so important to qualify every answer you give with what you are basing your answer on. The problem remains that there are no dictionaries and far too often attorneys or the public may not realize that there even is a barrier present.

How we can work more effectively together and walk that line is a difficult one and if anyone has ideas that have worked well, let me know. To me the best we can do is help the attorneys we work with understand that words matter. They already understand this concept in the court room they just need to understand that there is another language spoken by scientists.

I love how the article I mentioned above ends:

"So, scientists are changing the message. It is a subtle change, but important. When reporters like me ask the question, "Was the flood, or the drought or the tornadoes caused by global warming?" The scientists now respond, "No single event can be attributed to global warming, but we told you this was going to happen.""

To scientists that's the compromise you'll get and it's the best our integrity will allow.

Lost in Translation: Science Speak vs. Legal Speak

One day not too long ago, I sat on the stand going back and forth with opposing counsel.

There was no major disagreement. Actually, there was no real disagreement at all. The problem was that we were speaking in different terms. At one point, opposing counsel smiled with a sigh, clearly giving me that look that said he knew I was never going to agree with him because he was the "opposition." I smiled back knowing what he was thinking and knowing that he was wrong.

I wasn't trying to be difficult. I usually try to be fairly pleasant when I'm testifying...I know, shocker right? Although I will admit that when counsel becomes hostile my testimony can become rather short. Kind of like this wonderful scene from "Better off Ted."

Female Lawyer: Were you involved in the development of this product? 
Veronica: Yes. 
Female Lawyer: And how would you summarize the company's reaction when they found out that the women who used this product were savagely attacked by insects? 
Veronica: Ouch. 
Female Lawyer: Will you elaborate on that, please?
Veronica: No. 
Female Lawyer: Can you describe your job? 
Veronica: Yes. 
Female Lawyer: How would you describe your job? 
Veronica: Cleverly
Anyways, I digress.
In normal life when you are trying to explain science to your friends or family and they say something back that shows that they understood the gist of what you said, then you agree that they are correct. Close enough, right? That can never be the case in the courtroom, because if you agree to something as "close enough," then you will immediately have to backtrack with the follow-up questions, because you've essentially agreed to something that wasn't accurate in the first place.
And this was our issue at that particular moment. What he was saying was indeed "close enough," but it wasn't quite right.

Part of the problem is that scientists and lawyers speak different languages. Truly. It's like American English versus British English. It's all English, but if a Brit asks for a fag in the US...well, you see the problem. There is a communication issue. Our problem at that moment was that one phenomenon was actually first pass metabolism and not elimination. Yes, it's "eliminated" from the body, but it's not exactly what we're talking about when we discuss elimination rates. He was frustrated that I wouldn't agree, and I was frustrated that he was just repeating the same questions.

The especially frustrating thing about this situation (that I and others have been in many, many times) is that it can all be cleared up by one word: "Why?" If he had simply asked "Why is that not the same thing?" I could have launched into a description that may have clarified the situation and made clear to him that I was not trying to avoid his questioning, but that we had a difference of terms.
I don't know why that question is never asked. Perhaps it's because attorneys are used to factual witnesses or perhaps they simply don't want to ask the question when they don't know the answer. This is actually why direct testimony tends to be easier. They ask open ended questions and essentially allow you to drive the bus, since they know what your testimony will be. Opposing counsel wants to keep your answers as short as possible to avoid you driving the bus in a direction they don't want to go. The result though is that you argue over minutia and terms as opposed to substance.

I actually have an answer to this. Ready?
Depose the expert.

Yeah, that's it. If you depose the expert you will have some idea of what their testimony will be and you won't be afraid of the "whys." It sounds obvious. It is obvious! Yet, though the cases I have provided testimony in number in the thousands, the number of times I've been deposed only number in the dozens. I'm not sure why that is. Perhaps their clients don't want to increase the billable hours. Perhaps the science is intimidating or maybe they think there is no point because the expert will provide testimony like my example above. Perhaps my attorney friends can elucidate.
A good expert witness will seek to clarify not obfuscate. As I've said before, the expert witness is speaking for the science. They should be making sure that the attorneys, judge and jury all understand what the science means. Having disagreements simply because one party is speaking British English and the other is speaking American English is counterproductive. Ask why. If you're concerned about the expert driving the bus then ask the why's during deposition. The witness may not be trying to be difficult.

There are many words where this language barrier appears. In many cases, myself and my science colleagues have become accustomed to the legal definition of the word and simply agree if it is being used in a legal context. There are many words where the communities have different definitions, but one of the most common words tends to be "accurate." It is a given that when scientists use the word accurate, that they mean within the accepted uncertainty for that test. When lawyers use the word accurate they mean that the value is exactly (to whatever decimal place it is) the number. Part of the language barrier comes in because either party doesn't realize that there is a language barrier.
Perhaps a translation dictionary would be helpful, but until that dictionary is written, it's probably just a good idea to not be afraid to ask the questions.
