Hilarious Lesson in Critical Thinking: “Why Can’t You Use Phones on Planes?”

Posted by mattusmaximus on August 18, 2013

I just wanted to share a hilarious video from the folks at CollegeHumor.com titled “Why Can’t You Use Phones on Planes?” or, as I like to call it, “Airplanes are magic!”  It is, in my opinion, I neat and quick little lesson on critical thinking and how we often accept the most silly explanations without much thought.  It’s also really damn funny (note there is a little strong language).  Enjoy 🙂

Loch Ness Monster Activity is Likely Just Seismic in Nature

Posted by mattusmaximus on July 8, 2013

I ran across two articles recently about the latest research regarding the Loch Ness Monster.  And by “research” I really do mean serious scientific work: it seems that many supposed Nessie sightings over the years have been accompanied by audible rumbling and gas bubbling up to the surface of Loch Ness.  There seems to be a plausible geological (note: “geological” does NOT equate to “big freaking monster”, just to clarify) explanation for these phenomena.

As a lesson in critical thinking (or a lack thereof) in the media, let us compare the coverage of this research from two different sources, the Scientific American blog and the Huffington Post.  First, the SciAm blog…

The Earth-shattering Loch Ness Monster that wasn’t

Summer is traditionally Silly Season, when newspapers publish strange stories about aliens and monsters again and again to bridge holiday time – and so will July on “History of Geology” be dedicated to frivolous science stories…

In 2001 the Italian geologist Luigi Piccardi presented during the Earth Systems Processes meeting in Edinburgh a hypothesis explaining the supposed appearance of the sea/lake monster “Nessie” as a result of geologic forces.

According to Piccardi’s idea the historic description of the monster – appearing on the surface with great (earth)shakes and rumours – could be associated with bubbles emanating from the bottom of the Scottish lake of Loch Ness in response of seismic activity along the Great Glen fault system, passing below the lake. …

… Not only biological constrains, also the geology don’t seems to support the existence of an earthshaking monster in Loch Ness.  Common earthquakes from the Loch Ness area range between magnitude 3 to 4, larger events were recorded only in 1816, 1888, 1890 and 1901. These earthquakes don’t coincide with the years of supposed increased activity of Nessie (like 1933). Even the largest Scottish earthquakes were anyway too weak to cause any observable effects on the surface of Loch Ness (curiously the great earthquake of Lisbon in 1755 generated waves on Loch Ness, but no Nessie sighting is reported for this year).

Piccardi himself sees the value of his hypothesis more in the possibility to make geologists aware of the geological origins of some myths, as to propose verifiable cryptozoology.

Well, that seems pretty good: a well thought-out article regarding an area of actual scientific research, even going so far as to note the limitations of Piccardi’s hypothesis.

Now, let’s see what the HuffPo has to say…

Loch Ness Monster Mystery Solved? ‘Nessie’ Just Bubbles From Seismic Activity, Geologist Says (VIDEO)

… The first claimed sighting of “Nessie” occurred in the sixth century, according to Scientific American. Legend has it that the creature appears along with earth tremors and bubbling from the bottom of Loch Ness, one of Britain’s largest freshwater lakes.

Formed as a result of a long-ago collision between the northern tip of Scotland and the rest of Britain, the loch sits over the 62-mile Great Glen fault line. Piccardi argues that this position may have fueled centuries of Loch Ness Monster rumors.

“Loch Ness is exactly on the fault zone,” Piccardi said in 2001, according to The Telegraph. “When there are small shocks, it can create a commotion on the water surface. Along the fault there can be gas emissions, which can create large bubbles on the surface. There are many surface effects which can be linked to the activity of the fault.”

But Piccardi’s theory is not without critics, especially among Loch Ness Monster enthusiasts like Gary Campbell, president of the Loch Ness Monster Fan Club in Inverness, Scotland.

“Most of the sightings involve foreign objects coming out of the water. There’s two most common — one’s a hump, and the other is a head and neck,” Campbell told ABC News. “At the end of the day, there’s still sightings that are inexplicable. There’s something physical in there.” …

*facepalm*

Where to begin?  First of all, the fact that the HuffPo elevates a pseudoscientific hack – in this case, the Gary Campbell who runs a fan club for the Loch Ness Monster – to the level of a serious critic of a pretty plausible area of scientific research speaks volumes.  Apparently, to the HuffPo, “scientist” equates with “anyone who can make sh*t up”.

Next, pay attention to Campbell’s response: “At the end of the day, there’s still sightings that are inexplicable…” So that proves… what exactly?  That there isn’t a full explanation?  And how exactly does a lack of an explanation provide any validity to the explanation via invoking Nessie?  This is a classic argument from ignorance, and one could just as easily invoke leprechauns or unicorns as an explanation using such shoddy logic.

Last, but not least, is the final few seconds of the video at the HuffPo link, wherein the host shows some TV anchors moaning about how they don’t want to accept the geological research of Piccardi because they like the idea of Nessie.  The HuffPo host summed it up as follows:

“Sometimes you just don’t want scientific reasoning, and you just want to believe.”

Another Crappy “Lake Monster” Sighting in Canada?

Posted by mattusmaximus on November 11, 2011

Here’s a new one for the “you’ve-got-to-be-kidding-me” files: a halfway serious ABC News report on a really bad video shot by someone who claims to have evidence of a lake monster in Canada called Ogopogo (basically, the Canadian equivalent of the Loch Ness Monster).  Below is the video footage in question…

Oooh, scary!!!

That’s it?!!  That’s all there is to this supposedly astonishing story sweeping the world?  Some ripples/waves in the water which are likely caused by debris?

Sometimes I weep for humanity; if this is the best that cryptozoologists can come up with (and it pretty much is the best they can come up with), then it is no wonder they are mocked.  I think the following comment on the ABC News story sums it up best…

How come most quickly taken video’s are crystal clear but any UFO – Yeti – Nessie videos look like they were shot by a 2 yr. old with a Fisher Price camera???

‘Nuff said, folks.

Halloween: The Perfect Opportunity to Promote Skepticism!

Posted by mattusmaximus on October 27, 2011

My favorite time of the year is almost upon us: Halloween! 😀

I love Halloween not just because of the candy, the costumes, and the decorations (when else can you be a complete freak and it be socially acceptable?) but also because of the wonderful potential for promoting skepticism and critical thinking about various paranormal claims.  Let’s face it: at this time of the year, ghosts, witchcraft, psychics, and various other kinds of woo are on everyone’s minds, so why not take advantage of that fact and use it to inject the skeptical viewpoint on things?  I have found this to be a very effective teaching technique over the years, so that’s why I pass it along to you.

So in the spirit of the season (pardon the pun), allow me to share with you some links to various Halloween-ish skeptical resources that you can use, including a few of my earlier blog posts on the subject…

The “Loch Ness Monster”… of Alaska?

Posted by mattusmaximus on July 19, 2011

So there’s this video going around the Internet where some fishermen claim to have discovered a new “Loch Ness Monster”… in Alaska.  Here is the article and related video wherein witnesses claim to have found evidence of the creature…

The Loch Ness Monster of Alaska?

Move over, Montauk Monster. Step aside, Nessie. There’s a new sea creature in town–maybe. Footage of a 20- to 30-foot long creature caught on tape by fishermen suggest we have an Alaska bonafide marine-creature mystery.

The black and white footage from 2009 is by no means definitive. It is taken on a rainy day with a shaky camera, which make it all the more confounding. But you can check out the testimony of people who say they witnessed the creature’s appearance in the video above.

The Alaska-dwelling creature has been labeled a “Cadborosaurus willsi,” which means “reptile” or “lizard” from Cadboro Bay, British Columbia, where it was originally spotted centuries ago. Called “Caddy” for short, it has a “long neck, a horse-like head, large eyes, and back bumps that stick out of the water,” according to a report on MSNBC. …

So “Caddy” is the newest craze to hit the cryptozoology community of “monster hunters”, it seems.  Sadly, the supposed “evidence” here is no better than the best ever provided for the Loch Ness Monster, Bigfoot, or any other of the many mythical creatures that cryptozoologists claim exist.  In this case, we have a video of very poor quality – it is out of focus, grainy, and shot under bad weather conditions.

The claims that “this cannot be a sea lion” are also very questionable, because this assumes that the “humps” appearing behind the head that surfaces are actually part of the creature’s back without any kind of confirming evidence.  But here is a more reasonable and plausible explanation: as any seafarer knows, oftentimes when a sea lion, boat, or any other waterborne craft/creature is moving across the surface of the water it produces a regular pattern of ripples, such as those shown below…

Looking at this boat and its pattern of ripples from the side at a distance can certainly make it appear like there is a series of humps breaching the water behind the boat, but that is simply an illusion.  It is my guess that this is the same kind of illusion which has fooled these fishermen into thinking they are seeing “Caddy”.

One would think that if cryptozoologists are actually serious about investigating their claims, they could come up with something better than blurry photos, crappy video footage, and a profound lack of alternative explanations which are consistent with the environment they are observing.  Color me unimpressed.

Edmund (Pseudo)Scientific at it Again: This Time They’re Selling an “ESP Lamp”

Posted by mattusmaximus on June 20, 2011

You may recall that I made a blog post in 2009 – titled Edmund (Pseudo)Scientific Sells “Ghost Detectors” & Other Woo – wherein I strongly criticized the science teaching outlet called Edmund Scientific for caving in to the “ghost hunter” fad. They started to sell all manner of goofy things: ghost detectors (which are actually just electromagnetic field meters) and even DVDs on remote viewing. And all of this from a science teaching catalog – you might as well turn to the biology section and see creationist materials for sale!

[**Addendum (6/28/11): to get a good look at why I view such claims about EMF meters “detecting ghosts” so skeptically, take a look at this post – Convergence/Skepchicon Day 2: Ghost Hunting & Evidence Review – which outlines that so-called ghost hunters, when pressed, basically admit they aren’t doing any serious science.  But they want to look like it]

Well, not to be outdone in their tumble down the rabbit hole, Edmund (Pseudo)Scientific now has for sale an “ESP Lamp”.  I kid you not – they claim this thing can actually read your thoughts… as in extra-sensory perception… as in psychic woo-woo… and it only costs about $200!  But don’t take my word for it.  Read their own description of the product:

Edmund (Pseudo)Scientific’s “ESP Lamp and Money Burner” 🙂

Lead your own experiments in the mind’s possible influence on machines, PSI testing, and more with this colorful LED lamp. Four different color LEDs are lighted dependent upon a random number generated from a miniature Geiger counter included on the back. You may even figure out how to use it to tell the future. And, when you need a break from the lab, it makes a very interesting lamp too.

I’ll agree that it makes an interesting lamp, but that’s about the only thing in the description that’s factual.  Everything else is pretty much pseudoscientific gobble-dee-gook because many decades of research has clearly shown that no such phenomenon as ESP exists.  And that part about “telling the future”?  I suggest just saving your money and buying a Magic 8-Ball, because it would cost a LOT less and give you just as accurate results! 😉

But, sadly, that won’t appear to stop Edmund (Pseudo)Scientific from catering to the lowest common denominator in their quest for a quick buck off the gullible.  Unfortunately for them, they don’t seem to have done the math on the other side of things: how do they think science teachers across the country are going to react when they see this sort of garbage for sale in their catalog?  I know that I’ve spoken to a large number of science teachers who are quite upset about this (and justifiably so) and who are boycotting Edmund.  I’m among them, and I encourage all of my skeptical colleagues (especially those teachers among us) to do likewise: until Edmund (Pseudo)Scientific pulls products like this “ESP Lamp” and their “ghost meter” from their shelves – or at least until they advertise them in an honest and scientifically-accurate fashion – we should refuse to give them any business.

The Skeptical Teacher Talks About “Ghost Meters” on SETI Radio’s Skeptic Check

Posted by mattusmaximus on April 7, 2010

Okay, shameless plug time 🙂

This past Friday I had the priviledge of being interviewed by SETI astronomer Seth Shostak on SETI Radio’s monthly “Skeptic Check” segment. Apparently, Seth and executive producer Molly Bentley had caught the article that I wrote to Skeptical Inquirer magazine about the Edmund (Pseudo)Scientific ghost detector (my blog post on the subject is here) and how that once respected science teaching outlet had now decided to go down the rabbit hole of nonsense.

It’s a short interview (only about 6-7 minutes long), and you can listen to it here (fast forward to the 24:00 mark to get to my interview)…

Must-See Video: The G Hunters

Posted by mattusmaximus on November 27, 2009

I just wanted to share in this quick post with everyone a video I saw this last summer at The Amazing Meeting 7 in Las Vegas.  During the convention, our pals at the Skeptics Guide to the Universe shared their first effort at skeptical movie-making, a spoof of “ghost-hunting” shows which have become so popular these days.  For a more detailed analysis of why ghost-hunting is a load of woo-woo, click here. I hope you enjoy the show! 😀

South Park Spoofs “Ghost Hunters”

Posted by mattusmaximus on October 27, 2009

In the spirit of Halloween and skepticism, I shall be posting some things related to both in the days to come.  The first is a hilarious spoof of various “ghost hunter” shows by those wacky guys at South Park.

Despite the crudeness & vulgarity of their criticism, the South Park guys aren’t that far off the mark in pointing out the logical fallacy (basically, arguing from ignorance – a LOT of ignorance) committed by these lame-o doofuses who stumble around in the dark, scaring themselves for the cameras.  For a more detailed critique of “ghost hunters” and their pseudoscience, see my earlier blog post on the subject.

Edmund (Pseudo)Scientific Sells “Ghost Detectors” & Other Woo

Posted by mattusmaximus on September 14, 2009

A couple of weeks ago I became aware of something that, as both a skeptic & science teacher, shocked me: Edmund Scientific, one of the oldest & most respected outlets for selling science equipment for educational use, has gone over to the dark side.  They are actively marketing & selling paranormal woo…

edmund-woo-meter

What are these products that Edmund (Pseudo)Scientific is now selling on their website?  They are…

EMF Ghost Meter – This is nothing more than a standard EMF (electromagnetic field) detector, which usually detects EMFs that are low frequency, such as radio & microwaves.  I have no beef with Edmund selling EMF detectors (I even have one in my classroom), but what galls me is the manner in which they are marketing this device.  They are actually calling it a ghost detector – and by doing so they are giving credence to the pseudoscientific flummery of the paranormal woo-meisters!  As they say on their website:

Detect Paranormal Presences

The preferred unit of paranormal investigators, this Ghost Meter can be used by laymen with professional results. The unit responds instantaneously to EMF fluctuations and spikes in energy with a detecting range of 50 to 1,000 Hz. The VLF range is 1,000 to 20,000 Hz. An easy-to-read LED display and silent on/off push switch make for seamless, simple operation.

Such devices are often used by so-called ghost hunters as they bumble around in the dark, freaking themselves out at every cool draft of wind & creaky sound they hear.  In reality, there is absolutely no reason to think that EMF meters are detecting any kind of “ghostly entities”, as a simple application of Occam’s Razor often shows that what the meters are actually detecting is the low-frequency EM-waves given off by nearby lighting fixtures, electrical lines, or even the other equipment carried by the ghost hunters themselves!

But if you thought that was bad, it gets worse.  Here are some other gems that Edmund (Pseudo)Scientific is now selling…
