The Debunking Handbook

Posted by mattusmaximus on January 16, 2012

I recently listened to an episode of the Point of Inquiry podcast titled “The Debunking Handbook” which dealt with the question of how to most effectively go about “debunking” various myths, pseudosciences, and misconceptions.  The general thrust of the episode, which I highly recommend, is that most of us who call ourselves skeptics don’t really do that good of a job of communicating our debunking in a successful manner.  In fact, many skeptics actually make the problem worse by inadvertently reinforcing the bunk they are trying to debunk!

Needless to say, this kind of thing is right up my alley, and I think it is well worth your while to take heed of the advice given in “The Debunking Handbook”…

The Debunking Handbook: now freely available for download

Posted on 27 November 2011 by John Cook, Stephan Lewandowsky

The Debunking Handbook, a guide to debunking misinformation, is now freely available to download. Although there is a great deal of psychological research on misinformation, there’s no summary of the literature that offers practical guidelines on the most effective ways of reducing the influence of myths. The Debunking Handbook boils the research down into a short, simple summary, intended as a guide for communicators in all areas (not just climate) who encounter misinformation.

The Handbook explores the surprising fact that debunking myths can sometimes reinforce the myth in peoples’ minds. Communicators need to be aware of the various backfire effects and how to avoid them, such as:

Is There a Need for a National Center for Science Education on Climate Science?

Posted by mattusmaximus on October 30, 2010

The answer is YES! That’s because when you compare the tactics employed by climate-change deniers to those employed by creationists, they are practically identical.  Eugenie Scott, the director of the NCSE, elaborates in more detail…

Please consider supporting the NCSE and their important work. They are a valuable resource, one with whom I have consulted (and helped others consult) on numerous occasions.  Their experience in matters such as these is invaluable, so if you have any questions and/or concerns, contact them.

Skeptical App on the iPhone/Touch #2: “Skeptical Science” vs. Global Warming Deniers

Posted by mattusmaximus on March 20, 2010

As a quick follow up to my previous post regarding The Creationist Claims Index, there is a similar iTunes app regarding one of the latest & most venemous science-denial movements: global warming denialism. Whether you are conversing with someone who is merely ignorant of the science of climate change, or if you’re butting heads with a hardcore ideologue, you will no doubt find the Skeptical Science app to be of great use!

Much like its anti-creationist partner, the Skeptical Science app is well laid-out and indexed, making it a handy reference for those on-the-spot conversations that demand an immediate correction or rebuttal.  In addition, it’s free 🙂

Download it now at iTunes…

As the front page of the website states:

Scientific skepticism is healthy. Scientists should always challenge themselves to expand their knowledge and improve their understanding. Yet this isn’t what happens in global warming skepticism. Skeptics vigorously criticise any evidence that supports man-made global warming and yet eagerly, even blindly embrace any argument, op-ed piece, blog or study that refutes global warming.

So this website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?

Winter is NOT “Proof” of Global Cooling

Posted by mattusmaximus on January 13, 2010

One of the most public scientific topics in recent years has been that of human-influenced global warming, also known as anthropogenic global warming (AGW).  As I’ve posted before, for a variety of reasons – ranging from basic ignorance of climate science to the outright promotion of a cynical ideology – some people insist upon claiming that AGW (or even GW in general) is “false”, a “lie”, or a “hoax”.  In fact, some of the more extreme folks are claiming – in spite of all data to the contrary – that the Earth is actually in a period of global cooling.

Their evidence?… the most recent cold snap that has gripped the United States over the last week or two.  No, I’m serious – that is their “evidence”.  I’d be laughing my head off if it weren’t so sad that there are actually people who are seriously making this argument, so in true skeptical teacher fashion, I shall explain exactly where this argument falls apart and why it is inaccurate…

The primary flaw in this argument is good ol’ fashioned cherry-picking of data: the “coolers” are choosing to focus only upon data which supports their claims, while ignoring the vast amount of data which points in exactly the opposite direction. By focusing on just the weather reports over the last couple of weeks, or for only a certain part of the planet, they leave out the fact that climate is a phenomenon which is global in nature and that climate science is concerned with long term trends.  Essentially, they are confusing weather with climate.  Climate experts recently made this point in an Associated Press article which has been widely circulated.

Bottom line: when taking all of the data into account, both concerning the timeline as well as the Earth as a whole, there is a clear warming trend.

Lastly, I should point out that the intellectual vacuity of the “cooler” argument above cuts both ways.  Case in point: where I live in the upper Midwest we have, of course, been gripped by the recent cold snap, but weather (not climate) projections show that starting tomorrow (Wednesday, Jan. 13) through the weekend – at least – there will be an unusual warming trend.  In fact, temperatures will be well above freezing throughout the region, and this is in the middle of January!  ZOMG!!!

Thus, using the “cooler” method of cherry-picking, I could start going on and on about how this “proves” global cooling is false and “proves” that global warming is true.  I could also cherry-pick by stating that very high temperatures in some regions during the summer are “proof” of global warming.  But these would be ludicrous assertions, and I only mention them in jest as a way of making fun of the “coolers” and their pseudoscientific tactics.

So, putting such silliness aside, I suggest that we focus on actual climate science in this discussion, as opposed to using methods such as purposefully confusing weather with climate, cherry-picking, and so on.  In the long run, a rigorous application of the scientific method will allow us to see what’s really going on, and all else will be revealed as hot air. 🙂

Global Warming Deniers Get a Double-Dose of Pwnage

Posted by mattusmaximus on November 17, 2009

I’ve blogged here before about various claims made & tactics used by climate science deniers (I refuse to call them “skeptics” because they are not guided by evidence, merely ideology), but what I have to share in this post is truly damning stuff.  One of the things which is really interesting is what happens when a group of pseudoscientific ideologues (like global warming deniers) gets caught red-handed playing fast & loose with the facts…

Exhibit A: Statisticians Confirm Reality of Global Warming in Blinded Tests

Recently, one of the claims making the rounds has been that, contrary to the consensus within the climate science community, the Earth is actually entering a period of global cooling – this claim is patently fallacious, and anyone who has a basic understanding of statistics knows it.  But what happened recently, as reported in a widely-circulated AP story, really slams the door shut on this bogus claim: the temperature data for the planet was analyzed by a series of independent statisticians, all of whom found a warming (not a cooling) trend in the data.  And here’s the kicker: these statisticians didn’t know what the data were – in other words, the examination of the Earth’s temperature data was a blinded test!

Have you heard that the world is now cooling instead of warming? You may have seen some news reports on the Internet or heard about it from a provocative new book. Only one problem: It’s not true, according to an analysis of the numbers done by several independent statisticians for The Associated Press.

The case that the Earth might be cooling partly stems from recent weather. Last year was cooler than previous years. It’s been a while since the super-hot years of 1998 and 2005. So is this a longer climate trend or just weather’s normal ups and downs?

In a blind test, the AP gave temperature data to four independent statisticians and asked them to look for trends, without telling them what the numbers represented. The experts found no true temperature declines over time.

“If you look at the data and sort of cherry-pick a micro-trend within a bigger trend, that technique is particularly suspect,” said John Grego, a professor of statistics at the University of South Carolina.

This result puts paid to the oft-repeated claim by GW-deniers that there is a cooling trend in the data.  Of course, the only reason why these pseudoscientists were able to get away with their false claims for so long was because they, as professor Grego said, have been cherry-picking the data and presenting it incomplete & out-of-context in order to give the impression that the Earth is cooling.  But, as we’ve seen, once the experimenter & statistician bias is removed from the analysis, which is the whole purpose of doing blinded tests, a very real and consistent warming trend is revealed.

But it gets even worse for the GW-deniers…

U.S. Chamber of Commerce: Put Climate Science “On Trial”

Posted by mattusmaximus on September 1, 2009

According to this article from the LA Times, the biggest business lobby in the United States wants to hold a “trial” concerning global warming science…

The U.S. Chamber of Commerce, trying to ward off potentially sweeping federal emissions regulations, is pushing the Environmental Protection Agency to hold a rare public hearing on the scientific evidence for man-made climate change.

Chamber officials say it would be “the Scopes monkey trial of the 21st century” — complete with witnesses, cross-examinations and a judge who would rule, essentially, on whether humans are warming the planet to dangerous effect.

“It would be evolution versus creationism,” said William Kovacs, the chamber’s senior vice president for environment, technology and regulatory affairs. “It would be the science of climate change on trial.”

What a joke!!!  It is ironic that Kovacs mentioned evolution & creationism, for reasons you’ll see below.  Folks, this is ludicrous on so many levels…

William Dembski & the Anti-Science Crusade

Posted by mattusmaximus on August 4, 2009

Those of you who have followed the evolution-creationism battles for the last few years will recognize the name and infamy of William Dembski. Dembski is one of the top talking heads for the Discovery Institute, the intelligent design “think-tank” which rose to prominence in the 1990s, and he is guilty of pretty much every logical fallacy & dishonest debating tactic in the book in his promotion of ID-creationism.


But now, Dembski has decided to branch out from telling lies about evolutionary science, because apparently after the Discovery Institute’s embarrassing smackdown at the Dover trial in 2005, the creationist movement has decided to take their anti-scientific agenda into other areas, such as environmental science.  For details, see the following article on the Southern Baptist Conference’s website where Dembski recently outlined this broader attack on science.

Global Warming Denial: Full of Hot Air

Posted by mattusmaximus on April 25, 2009

As I’m going through my day at school earlier this week, I did the usual thing – after lunch I went by my mailbox.  Inside I find an article from a colleague of mine with the following message on a sticky note: “It’s nice to see a newspaper giving time to the conservative viewpoint on global warming.”  Argh.


Full disclosure: I tend to be more liberal than conservative in my personal politics, but to imply that there is such a thing as “conservative” science and “liberal” science does a grave disservice to science in general.  I might add this goes the other way as well – when Al Gore’s movie “An Inconvenient Truth” (AIT) came out a few years ago, I refused to watch it even though many of those on my side of the political isle were encouraging me to do so.
