 Lately I’ve been thinking about logical fallacies used in advertising and marketing. The argument from authority when someone in a lab coat tells you what to buy, argumentum ad populum which is “appeal to the people” because everyone else is buying this product so you should too.
One of my pet peeves is multigrain labels emblazoned on foods lately. Technically the food has more than one grain in it, but they are touting the product as something healthy when they have still stripped all fiber and goodness out, so the health benefits are still lacking. This is very popular in cereals, and unless you read the label you’d think you were buying something healthy, when really it’s just as junky as cocoa puffs.
The “no sugar added” label is another one I find quite vague. There are several different iterations of this one. No sugar added, sugar free, the [...]
My friend Charles composed the following email as a response to a ridiculous christian forward he got call “Untimely Deaths”. He thought I might like to share it with you. So here it is, including the angry christian email reply he already got and his reply to that at the end. His version had the classical large fonts, underlines and bold text that inflammatory emails often have, but for the web, I had to strip most of the formatting. If you decide to send this on to your christian friends, feel free to make them more at ease by using insanely large font sizes, underlines, unreadable colors, etc. 
 Do you have the COURAGE to Read this whole E-Mail?????
The TRUTH about UNTIMELY DEATHS!

Some years before, during an interview with an American Magazine, he said:
“Christianity will end, [...]
Butch, my awesome husband, found the following 4 act play with lobsters in trees. I have added a bit of information for your edumacation enjoyment. Who knew some lobsters were so daft?
Act 1: Post Hoc Ergo Propter Hoc (after this, therefore because of this). Since the event followed this one, that event must have been caused by this one.
 The logical fallacy known as The Slippery Slope wrongly assumes that one thing must lead to another, and another and before you know it you get to something awful. Therefore you can’t do the first thing. This is a very common fallacy. It’s also known as the Fallacy of the Beard.
In an argument, it is the situation where acceptance of a minor detail of the opposing position will greatly weaken your position.
This is Part 10 in a series about Logical Fallacies. We are going through one fallacy at a time. There are many types of fallacious arguments. I’m going to try to explain them with examples then find ways to help you refute those arguments when they occur. Please comment or email if there’s a particular fallacy you want me to tackle, or if you have success with refuting an argument using a good [...]
An interesting offer from ASPEX
November 10, 2009 2:54 PM – by PZ Myers
 I had my doubts about this; I got an offer from ASPEX corporation to let people get free scanning electron micrographs of just about anything. They make a desktop SEM (Scanning Electron Micrograph), and all you have to do is fill out a form and mail it in with your sample of a dead bug or a microchip or bacon, and presto, within a few weeks they’ll have it scanned in and the image available on their website.
I asked them if they knew how many readers I have, and they said no problem, they can handle it.
Huh.
Well, you heard them. Scavenge your trash cans, dig into your local sources of vermin and oddments, and send them in. I’m thinking this could be really fun for any school [...]
 Moving the Goalpost, or Raising the Bar, is a common informal logical fallacy in which the arguer, when presented with evidence against one of his claims, redefines his claim without acknowledging the validity of the evidence and counterargument. In other words, the arguer doesn’t like what he hears so he simply changes what would satisfy the argument. In doing so, it can make any claim at all vacuously true and invulnerable to reasoned disproof.

 In our book club right now, we are reading Nonsense: Red Herrings, Straw Men and Sacred Cows: How We Abuse Logic in Our Everyday Language by Robert J. Gula. It’s very interesting as it goes through emotional language and logical fallacies in several ways that make them easier to understand. Robert Gula wrote the book in the 1970’s which is interesting in its nostalgic examples.
But what I wanted to share with you was something from chapter 1 that I thought was quite valuable:
First, some general principles. Let’s not call them laws; and since they’re not particularly original, I won’t attach my name to them. They are merely a description of patterns that seem to characterize the ways that people tend to respond and think. For example, [...]
