Solal Technologies sue South African writer

Quackometer reports that Solal Technologies is suing Kevin Charleston. In the knowledge-supressed environment of South Africa, Charleston had the temerity to bring to light that Solal Technnologies’s claims for HIV treatment are not scientifically supported.

The Maya calendar, 2012 and the end of the world

Mauricio-José Schwarz at JREF gives a very good description of the nonsense and misinformation being promoted by various people caught up in what they believe is the Mayan prophecy for the end of the world. A must read. Don’t fall for the New Age garbage.

Why do people believe in nonsense?

I think most of us know that homeopathy is nonsense, that it’s nothing more than a placebo. And I thought I’d heard all homeopathic nonsenses until I watched this:

Crazy Homeopathy Lady Charlene Werner Explains Physics

It’s almost as if she’s had a dose of woo from Deepak Chopra!

This raises an interesting question: Why do people believe in nonsense? The great Carl Sagan explored this many years ago in his book “The Demon-Haunted World: Science as a Candle in the Dark”, and by Michael Shermer in several of his books such as “Why People Believe Weird Things: Pseudoscience, Superstition, and Other Confusions of Our Time”.

It seems to me that people want to believe in something fantastical regardless of the weight of evidence that show that their beliefs just ain’t so. Is this a result of their upbringing, a failure to use tools such as common sense and critical thinking? Education is always important but we are unlikely to be totally free of wackos.

Why are atheists so rude?

Quite funny.

The problem, of course, is that any form of discussion based on evidence and reason inflames the religious who just cannot accept that their world view is based on falsehoods, lies and immoral concepts. As far as they’re concerned, such arguments are shrill, disrespectful and rude. I have very little time to pander to the delusional and irrational, so I say it like it is.
