“Educating/Debunking: What’s the Difference?” Video from Dragon*Con 2011

Posted by mattusmaximus on January 24, 2012

This past September I attended Dragon*Con in Atlanta, and I participated in many events and interviews, etc.  However, in my role as both a skeptic and a teacher, one of the most fruitful things I did was to participate in the Skeptrack discussion of how to approach the question of debunking in the context of education.  The panel was an important discussion moderated by JREF President, D.J. Grothe on the topic of Education vs. Debunking, how they are different and when and how each should be used to the greatest effect.  The discussion dealt with the issue in the context of the classroom as well as beyond in the broader culture.  Below is the video footage of the discussion; I hope you find it useful…

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:

It’s Equinox Time, So Balance Some Eggs for Science!

Posted by mattusmaximus on September 22, 2011

Tomorrow, September 23rd, is the autumnal equinox in the northern hemisphere, and it is on this occasion that I like to inject a little skeptical and critical thinking fun into my physics classes.  Most of us have heard of the urban legend about balancing an egg on its end during the equinox – the thing is, this is true!  The myth is the implication that one can only do this on the equinox, when – in fact – you can balance an egg on end pretty much any time you want.

Case in point, here’s a couple of photos of me balancing eggs on their ends during the time of year exactly opposite to the equinoxes…

During the summer solstice…

And during the winter solstice…

In addition, here’s a nice Youtube video showing some tips on how to accomplish this trick:

The reason why this trick works boils down to simple physics: it’s called unstable equilibrium.  If you have a flat and level surface on which to perform this trick, and there aren’t a lot of vibrations around, then chances are you can balance a number of eggs in a standard dozen pack.  As long as the eggs are relatively smooth on their ends (look closely and you’ll see some bumps on some of them) and you are very patient, then with some practice pretty much anyone can perform this trick.  The Bad Astronomy blog has a pretty good rundown on the physics as well.

So the next time you hear someone pass along the “eggs can be balanced only on the equinox” myth, whip out some eggs and balance away.  It’s a quick, easy, and fun way to advocate for skepticism and science 🙂

“Education vs. Debunking” Panel at Skeptrack, Dragon*Con 2011

Posted by mattusmaximus on September 17, 2011

While I was at Dragon*Con a couple of weeks ago, one of the things I did was to participate in a very useful panel discussion on the Skeptrack.  The title of the panel was “Education vs. Debunking”, and the panel was an important discussion moderated by JREF President, D.J. Grothe on the topic of Education vs. Debunking, how they are different and when and how each should be used to the greatest effect.  The discussion dealt with the issue in the context of the classroom as well as beyond in the broader culture.  The entire discussion was recorded and is being broadcast on the Skepticality podcast, so if you’re interested check it out…

Placebo Band Bracelets and Opportunity for Easy Skeptical Activism

Posted by mattusmaximus on August 14, 2011

I have written before on this blog about the scam called Power-Balance, and how that company has raked in huge gobs of cash by essentially lying to its customers.  In fact, in Australia the company has basically been banned for false advertising, and fortunately more and more people are cluing in to this nonsense here in the United States.  But to help along everyone’s critical thinking skills as well as expose the Power-Balance for the scam that it is, I want to pass along to you a wonderful opportunity to engage in some easy and fun skeptical activism.  Dear reader, I give you the Placebo Band!

The Placebo Band: image courtesy of SkepticBros

There are two outlets for the Placebo Band, the original one at SkepticBros out of Australia and a new North American affiliate at the Placebo Band Store.  In addition, you can find testimonials on the power of  the Placebo Band, as well as instructions on how to educate your friends on how the whole thing works (hint: think placebo effect, hence the name 😉 )

For example, here’s a real* testimonial on the power of the Placebo Band.  Order yours today!!!

*And by “real”, I mean totally fake 🙂

Happy Summer Solstice: Skeptical Egg-Balancing Fun!

Posted by mattusmaximus on June 21, 2010

Happy Summer Solstice everyone! It might seem a strange thing to be celebrating, this specific position of Earth in its orbit around the sun, but we skeptics have our reasons. This, of course, has to do with the old myth of being able to balance eggs on their ends only during either the vernal (spring) or autumnal equinox – of course, all references are in regards to the northern hemisphere.

But wait, it’s not the equinox, so why bring up this myth now? To debunk it, of course. According to adherents of this myth, usually the same folks who are into astrology-related woo, during the equinoxes “things line up cosmically” (probably some misunderstood reference to the fact that the length of day & night are the same), and this should result in the capability to stand eggs on their ends.

The funny thing about this particular myth is that it contains a kernel of truth… you can stand an egg on its end on the equinox, just as you can at any time of the year – even the solstices, as far away from the equinox as you can get. Case in point, last summer (on June 21st, the summer solstice) I balanced three eggs on end in my kitchen…

Solstice Eggs

And this past winter solstice (well, close – on December 24, 2009), while visiting family for the holidays I balanced an egg on end in their kitchen…

These supposedly “cosmic events” took me all of just a few minutes to accomplish – with a little practice, it’s easy to do. To understand why it is that eggs can be balanced in this manner, it is more helpful to look to the science of physics rather than the pseudoscience of astrology – this link at the Bad Astronomy blog explains in more detail.

So, the next time you hear someone make this loony claim, have a little fun with it – whip out the eggs and balance away!

Happy Winter Solstice! — Time to Balance Those Eggs

Let’s balance some eggs, kids 🙂
