Another Door Study

Here is another really good video about Inattentional Blindness and Change Blindness.

This video is particularly good because of the commentary from Daniel Simons, one of the main researchers of this phenomenon.

Someone doesn't understand the First Amendment

Here is a nice example of a Slippery Slope:

Billboard reads, "Attention: Lunatic Atheists and their Lawyers, Anti-God is Anti-American, Anti-American is Treason, Traitors lead to Civil War"

One of the oldest political tricks in the book

Here is a very nice example of a Red Herring from The Simpsons:

As we can see, Mayor Quimby is trying to distract the public from taxation issues by blaming immigrants for all their problems. Although this episode, "Much Apu About Nothing" originally aired in 1996, current political events reveal the extent to which this is, despite being fallacious, still an enormously effective political strategy.

John Oliver on Media Consolodation

As mentioned elsewhere on this blog, I am a big fan of Chomsky and Herman's Propaganda Model of the Media. The first of the five filters that make up this model concern the size, concentrated ownership, and profit-orientation of the media. The argument here is that these factors shape or filter the content of the media we receive in the US.  A very good example of exactly this point comes from an episode of Last Week Tonight With John Oliver that first aired on July 2, 2017:

As an addition to John Oliver's analysis, a video recently surfaced showing how Sinclair is using its media empire to promote a particular point of view. Video and analysis of this can be found here.

Donkey Brain!

Denying or Negating the Antecedent is a formal fallacy that has the following argumentative structure:
  1. If P, then Q.
  2. Not P.
  3. Therefore, not Q
This fallacy is often confused for the valid argument Modus Tollens which has the following structure:
  1. If P, Then Q.
  2. Not Q.
  3. Therefore, not P. 
The comedy show It's Always Sunny in Philadelphia presents an excellent example of Denying or Negating the Antecedent in the following clip:

If we reconstruct the argument it goes:

  1. If one has donkey brains, then they make foolish decisions.
  2. Frank does not have a donkey brain.
  3. Therefore, he does not make foolish decisions.

Did doctors really believe this?

Here is a great example of the Appeal to Inappropriate Authority, a fallacy in which one relies on some "putative" expert who shouldn't really be relied upon.

An ad from the 1950's for Camel Cigarettes. The ad copy says, "Mored Doctors smoke Camels than any other cigarette!"
Picture of a doctor holding a cigarette with a pack of Camels on his desk. The caption reads, "More Doctors Smokle Camels than any other cigarette!"

Note that this ad does not claim that doctors recommend smoking. Instead, it implies that Camel cigarettes are healthier than other cigarettes because more doctors smoke them. While the ad isn't explicit, there is a clear Appeal to Authority in the claim that Camel cigarettes are preferred by doctors.

These ads were fairly common back in the 1950's until the a number of scientific studies started to be released that began to draw a clear connection between smoking and lung cancer. In addition, the FTC began to step up its regulations on tobacco advertising, essentially making ads like this illegal because they implied that some cigarettes were healthier than others or that cigarettes themselves did not pose any health risks. Much of this was dramatized on the TV show Mad Men, particularly the premiere episode "Smoke Gets In Your Eyes," which is a nice transition to this second example sent to me by a student:

Picture of a Physician holding a pack of Lucky Strikes. The caption reads, "20,679 Physicians say 'Luckies are less irritating' 'It's toasted' Your Throat Protection against irritation against cough.

Here is a fantastic video that nicely illustrates Chomsky and Hermann's Propaganda Model of the Media.

Sometimes, the media just lies.

With all the debate and hand-wringing swirling around fake news, it is sometimes important to remember that many mainstream media outlets, particularly on the right, sometimes just lie. Case in point is this story from a Swedish newspaper about a Swedish "Security expert" Nils Bildt who appeared on Bill O'Reilly's show The O'Reilly Factor on Fox News.

Screenshot from the The O'Reilly Factor identifying guest Nils Bildt as a "Swedish Defense and National Security Advisor. "

As you can see, he is identified as a "Swedish Defense and National Security Advisor," and he was on Fox News to spread the lie that Sweden is extremely dangerous due to the influx of refuges from Muslim countries who have settled there in recent years.

As the above story from Dagens Nyheter (one of the largest Swedish daily newspapers) indicates, Bildt has no formal affiliation with the Swedish Government, and has not even lived in Sweden since 1994. Furthermore, the article is a further example of the relative shock the people of Sweden have felt since being accused by President Trump of being a hellhole due to their acceptance of refuges fleeing the chaos in Syria and the Middle East. Needless to say, most Swedes have no idea what Trump is talking about. And for O'Reilly to continue to spread this falsehood is a real stain on the media and journalism generally.

A handy chart for evaluating news sources

This is a nice infographic making the rounds that provides some helpful advice on how to evaluate news sources. I tend to think that some of the more centrist outlets tend to still have problems (see critiques of the mainstream media elsewhere, especially Chomsky and Hermann's Propaganda Model of the Media), but this is still a very useful resource.
