Here Be Dragons: An Introduction To Critical Thinking

Brian Dunning offers this 4o minute video to introduce critical thinking. From his site he says, “Most people fully accept paranormal and pseudoscientific claims without critique as they are promoted by the mass media. Here Be Dragons offers a toolbox for recognizing and understanding the dangers of pseudoscience, and appreciation for the reality-based benefits offered by real science.”

Thanks, Gerald!

2012 Doomsday Fast Approaches!

OMG, yo! Hide the good silver! Run for your lives! The Mayans say the world will end December 21, 2012 and that’s only 2 years and a month away! Whatever will we do?!

Of course the Mayans themselves didn’t survive till 2012, so maybe they aren’t the best group to ask about such things.

Recently a friend of mine mentioned the 2012 phenomenon as if it were true. Unfortunately I didn’t have the hard facts at my disposal so I told him it’s not going to happen and left it at that. But I thought I’d look up some more information so when your mother starts talking about the end of the world, you will have some facts to back you up.

Lucky for me, NASA and Wikipedia have pages to explain where the concept came from and what scientific…

Some Great Advice by Robert Gula

Today (November 15) is our final look at Nonsense: Red Herrings, Straw Men and Sacred Cows: How We Abuse Logic in Our Everyday Language by Robert J. Gula.

I really wanted to share part of chapter 17 with you. Mr. Gula lists the most important principles to be gleaned from the rest of the book. I highly recommend getting the book and reading it. It has really helped me think more logically. The other thing it’s helped me with is to realize when someone has used a logical fallacy on me. I might not remember the name, but I remember that it is nonsense. It sort of gives me a red flag when someone uses bad logic in an argument. I think that’s pretty invaluable.

So here’s the list of important principles from Robert Gula:

Logical Fallacy: Correlation Does Not Imply Causation

Here are several examples of people trying to use the logical fallacy of Correlation and Causation which is loosely defined as follows: Just because two events occur together does not mean that one caused the other. Or just because two variables have a connection does not automatically imply that one causes the other.

1. From a creationist website:

1. “All crime is a result of sin, and of course there was crime before Charles Darwin promoted evolution, but as the theory increased so did the crime rate. Today Creation is not taught, even as a theory, in our schools, therefore children have nothing to base their morality upon. As God has been removed from the classroom, so all kinds of evil has multiplied on our streets. Remove the Bible and you take away the conscience of the nation. Evolution has absolutely nothing to offer with regards

Logical Fallacy: Appeal To Emotion

OK, we’ve all seen the ads on TV for some alarm company where some creep is watching an innocent woman or child or both and kicks open their front door in broad daylight. All of a sudden, an alarm shrieks to life, the criminal makes eye contact with his intended victim and runs off.

I can’t tell you how much these ads offend me. First of all, anyone psychotic enough to kick in the door of someone’s home in broad daylight is not going to turn tail and run off just because some alarm goes off. The first thing they are going to do is get hold of their victim to control their movements, that way they can keep them away from any exit or phone.

The next thing they’ll do is bind the victim with something so they can be controlled with minimal effort. So by the time the…

Logical Fallacy: Cherry-Picking

Cherry-Picking is when you count the hits and ignore the misses. It is used when only certain quotes, data, studies or research are used to support an argument while ignoring other valid and credible quotes, data, studies and research. In my personal experience, cherry-picking is rampant in the religious population.

Examples:

When christians speak of the bible, they invariably cherry-pick the parts that support whatever they are trying to get across. Homosexuality is a prime example (leviticus mentions it twice). Of course they don’t mind eating shellfish or wearing a poly-cotton blend shirt, which is expressly forbidden in subsequent chapters. We’ve all dealt with the hypocrisy of the old testament, especially the homosexuality issue. Instead I’m going to share a bit of the new testament, which most people use to show how kind and loving jesus was. I’ll stick to the gospels for this exercise, to make my point:

How To Argue

We’ve begun talking about logical fallacies and different arguments here and at the Freethinkers Morgantown Book Club. So hopefully this will be interesting and helpful to you.

Almost all of us argue or have discussions. But there’s actually a right way and lots of wrong ways to go about it. As an ethical person, I don’t really want to do it wrong because that’s being dishonest and unfair. I am definitely not a debater, which is where people actually use logical fallacies on purpose to win an argument. I don’t really care for debates because they seem forced to me. It’s about winning, not about finding out the truth. I think the main reason I hate arguing is because most people fight dirty. I am sure I’ve done it too, mainly out of ignorance. Now, with the following information, we can argue more logically.

Here is a pretty close…

You Are Wrong Because:

Here’s something Rachel over at Morgantown Brights shared with me since we’ve been talking about logical fallacies lately.

Nothing can reduce your happiness faster than an argument with an irrational co-worker. You can’t win irrational people over to your side by your superior reasoning abilities. And you can’t talk them into getting inside abandoned refrigerators and closing the door to see if the light goes out. There simply aren’t that many abandoned refrigerators. If you use the refrigerator in the break room, everyone will start whining about how there’s no room for yogurt. Until there are more refrigerators, or less yogurt, you will find yourself in frustrating discussions that can have no good endings.Trying to win an argument with an irrational person is like trying to teach a cat to snorkel by providing written instructions. No matter how clear your instructions, it won’t work. Your best strategy is to

Logical Fallacy Land 2: A Treat For You

I have a treat for you. The other day I posted a horrid creationism video by John Morris Pendleton and suggested that we practice pointing out logical fallacies by refuting the lies and nonsense he was spewing forth. But I could barely handle watching the video myself, never mind muddle through it point by point, so I’m sure it’s similar for you.

Still, I think there’s validity to refuting such arguments as practice. According to a recent Gallup poll, only 39% of Americans say they believe in the theory of evolution, while 1/4 say they do not believe in the theory.

Lucky for us, Brent told me about a set of videos that go through Pendleton’s step by step and refute them. How awesome!

Here is the first one of 4. (about 10 minutes long):

For the rest of the videos, click…

Logical Fallacy Land

Here is a video sent to me by an atheist who asked for help in refuting it. It was sent to him by an “arrogant christian”. I’ll warn you, it’s almost 27 minutes long and incredibly irritating to watch. But I’m sharing it with you because we are working on logical fallacies for our next meeting, as well as reading Nonsense by Robert Gula for the Book Club.

It would be awesome if we all could comment or email Neece with refutations against all the lies and logical fallacies used. If you send in an email, I’ll post it to share with everyone. Or comment below and we can all add to it little by little.
