The Schneider Quote

Dr Schneider explaining something.

Dr Schneider explaining something.

Dr Stephen Schneider, of Stanford University, is a well-respected climatologist who is also quite active in the media and politics – chances are you’ve seen him in something like The 11th Hour, read one of his books, or read an interview with him in the newspaper. Chances are, you’ve also seen the following quote attributed to him:

On the one hand, as scientists we are ethically bound to the scientific method. On the other hand, we are not just scientists but human beings as well. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. Each of us has to decide what the right balance is between being effective and being honest.

When I first saw this quote in a YouTube comment, I assumed it was completely fabricated. But then I did a Google search on the exact quote and found thousands of hits. Still, they were all from either blogs or newspaper editorials, which are quite low on our credibility spectrum, so I felt sure there must be more to the story. My guess was that it was taken completely out of context and/or rearranged like one of those “found poems” they make you write in elementary school. I had seen Dr Schneider’s work before and he seemed like much too reasonable a man to say something like this and mean it.

I wrote an email to Dr Schneider, asking if he could quickly explain where the quote came from, even though he’s probably been asked about it countless times. I’ve found that university professors, even those like Dr Schneider who are undoubtedly busy, are quite good about answering email. As long as you’re polite and show a genuine interest in having your question answered, they write back quite promptly with some direction for you.

“You have guessed right,” he wrote. “It is a major misquote….leaving out the last sentence, leaving out the context….it is all explained in the Mediarology section of my website.”

Those who are really interested in this story are welcome to go and read that explanation, but I’ll summarize it quickly here for the rest of us. In a 1988 interview with Discover magazine, Dr Schneider was explaining how the media does not give climatologists a lot of time to explain anything thoroughly. As a scientist, he has an obligation to include all error and uncertainty measurements in statements, like any legitimate scientific report would. But as a human being, he needs to convey his message to the public in the couple of sentences journalists allow him.

This was the original quote:

On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but – which means that we must include all doubts, the caveats, the ifs, ands and buts. On the other hand, we are not just scientists but human beings as well. And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climate change. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This “double ethical bind” we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.

With the full quote, it’s easy to see that Dr Schneider was attacking, not supporting, the “sound-bite system”. But an attack editoral from the Detroit News selectively cut out parts of the above quote, publishing the following:

On the one hand, as scientists we are ethically bound to the scientific method. On the other hand, we are not just scientists but human beings as well. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. Each of us has to decide what the right balance is between being effective and being honest.

His message is completely changed.

So what should we learn from the sad story of the Schneider quote?

Whenever you see something particularly outrageous-sounding, don’t just accept it as fact. Find the original source, the original interview. Email the guy if you have to. Figure out what they really meant. Then you have enough information to decide what to believe.

How it All Ends

For anyone who hasn’t yet heard of these video series –

Greg Craven is a high school teacher from the States who put together six hours of video explaining why we should act on climate change. Don’t be scared by the “six hour” thing – all his arguments are condensed into the first, 10-minute long video.

Still skeptical? Chances are, whatever you’re thinking of is covered in the other five hours and fifty minutes. Check out the rest of the videos here.

The Credibility Spectrum

Let’s face it, there’s a lot of “climate science” out there that’s absolute rubbish.

Whichever side of the debate you’re on. Whether you believe global warming is a political hoax or that all skeptics are funded by Exxon. No matter what your opinions are, chances are that you’ve seen or read claims that you dismiss as outlandish.

Type “climate change” into Google. Within seconds you can find statements that the Earth is warming or that its temperatue is stable (or cooling since 1998!). You can find “proof” that the warming is caused by the sun, volcanoes, flaws in the temperature data, or fossil fuel burning. You can read that the Hockey Stick graph is broadly accurate, or that it was manipulated by the IPCC to agree with a predetermined conclusion.

Whatever you read about climate change, chances are that there’s another source saying the opposite thing. It’s not like we’re all climatologists who can see straight through misinformation. So how do you possibly sort out what to believe?

When people ask me this question, I invariably respond with, “Assess the credibility.”

The “climate change analysis” you read could be from a national academy of science, or from a blogger. It could be from an atmospheric physicist or a economist. It could be from a scientific journal or a political think-tank. If we calculate credibility to be “expertise + objectivity”, it’s obvious that some sources merit more weight than others.

I’ve put together a climate change credibility spectrum, inspired by Greg Craven from the Manpollo Project. This is a basic way to assess credibility and assign weight to a source. Keep in mind that this is only a guideline. The sources in the middle, especially, could be shuffled around based on the situation. The spectrum is also only used for scientific statements, such as “the Arctic is losing sea ice”. Matters of policy, such as “cap-and-trade is our best bet”, are much more a personal opinion.  

  • At the bottom of the spectrum we have the individual. This is someone with no formal education in the field of climate science. Bloggers generally fall into this category, which is why I plan to refrain from creating my own “expert analysis” of data on this blog.
  • Above that we have the professional. This is someone who is not a scientist, but is in an occupation that requires them to keep up to date with science. High school teachers are a good example, as well as politicians or CEOs.
  • Then we have the non-publishing scientist. Someone with a scientific background, but who is not currently publishing peer-reviewed literature, does not necessarily follow methods which are accepted by the scientific community. They have a good knowledge of science, but lack the “peer-reviewed” credential.
  • Above that is the publishing scientist in any area, such as medicine, physics, or chemistry. Even if they do not study climate change, they have the basic scientific background to understand it, as well as the “peer-reviewed” check on their scientific methods.
  • The publishing Earth scientist specializes in areas closer to climate science, such as geography, geology, or environmental science. They have a more in-depth knowledge of the way the biogeochemical systems of the Earth work.
  • The publishing climatologist (or atmospheric physicist/radiative physicist/any other area that’s so relevant to climatology that we can basically classify it as climatology) is the best you can get in terms of the individual professional. They understand more about climate change, and have more widely approved methods, than any other scientist.
  • Above the individuals come groups. Universities are generally quite up-to-date in their scientific knowledge, as they are training scientists-to-be, and have a large number of scientific professors behind their statements.
  • Peer-reviewed scientific articles are often written by more than one scientist, and have undergone an extensive review process. These articles minimize bias or misconceptions as much as science possibly can.
  • Finally, professional scientific organizations employ thousands of publishing scientists, have massive reputations to uphold, and often publish their own peer-reviewed journals. Their statements carry more weight than any others.

This isn’t to say that the NAS is infallible, or that the blogger is always wrong. The credibility spectrum is simply a tool used to decide how much weight to give a statement.

So go do some reading. Do some searching and reading and watching. See what individuals, professionals, groups and scientific bodies are saying about climate change. Assess their credentials. Decide who you’re going to believe.
