"Extraordinary claims require extraordinary evidence." -- Carl Sagan

"What can be asserted without evidence can also be dismissed without evidence." -- Christopher Hitchens

What is a logical fallacy? All arguments have the same basic structure: A therefore B. They begin with one or more premises (A), which is a fact or assumption upon which the argument is based. They then apply a logical principle (therefore) to arrive at a conclusion (B). An example of a logical principle is that of equivalence. For example, if you begin with the premises that A=B and B=C, you can apply the logical principle of equivalence to conclude that A=C. A logical fallacy is a false or incorrect logical principle. An argument that is based upon a logical fallacy is therefore not valid. It is important to note that if the logic of an argument is valid then the conclusion must also be valid, which means that if the premises are all true then the conclusion must also be true. Valid logic applied to one or more false premises, however, leads to an invalid argument. Also, if an argument is not valid the conclusion may, by chance, still be true. For a more thorough discussion of logical fallacies and how to structure a logical argument, see the New England Skeptical Society's article, How To Argue.

"No skeptic, to my knowledge, ever made a major scientific discovery or advanced the welfare of others."

-- Deepak Chopra (yes, he actually said that)

"The most exciting phrase to hear in science, the one that heralds the most discoveries, is not "Eureka!" (I found it!) but That's funny..." -Isaac Asimov



The scientific world view is full of awe and wonder. Understanding how truly awesome the universe is – in its elegant complexity, its staggering beauty, and the many intricate systems of which it is comprised – gives a profound feeling of connectedness and sparks the imagination. And it has the advantage of being real. -Steven Novella



The glory which is built upon a lie soon becomes a most unpleasant incumbrance. How easy it is to make people believe a lie, and how hard it is to undo that work again.
— Mark Twain

Saw this on Unreasonable Faith - too awesome not to see again and share!

Forgive me if this was posted before. I went through about 20 pages of comments and didn't find it. Too funny not to share.

The creationists don't invoke quantum much because it isn't in the bible. But yes invoking quantum is the new god of the gaps for new age types.

I found the following article on BBC.com: http://news.bbc.co.uk/2/hi/health/8211925.stm referencing the fact that WHO has condemned recommendations, esp. in Third World Countries, that it can be used for HIV, malaria, and even diarrhea. Then, I followed a link to the Society of Homeopaths from that article, and the simple explanation of what it is. They admit they "aren't sure" how it works, but now invoke Quantum Mechanics - is this the new strategy for avoiding standard scientific evaluation of pseudosciences? Has anyone else noticed this? I have seen the creationists mention it...

@Susan

I'm not sure would call that "communicating" - sounds like talking to a blow-up doll.
Comment by Susan Stanko on February 23, 2010 at 11:25pm
I have actually communicated with people who didn't understand why I would point out the tabloid sources that they used.
Comment by sacha on February 23, 2010 at 10:28pm
The majority of people read them over broadsheets because the majority of people do not want to have to think. Sad state of affairs.

@Talia

The Daily Mail and the Mirror are basically tabloids, It would be nice if more people realised that. I don't expect much from them, but last night BBC News 24 broadcast a "homeopathy cured my cancer" story.


For fuck's sake.
