For Discussion: Should I Write Only About Fake Stuff If It Is Well-Known?

A person who describes himself as a “pseudoscience fighter” e-mailed me to chastise me for writing about Prodovite last week. He felt compelled to offer me some advice. He made some good points; but they were things I had already thought about, and they didn’t change my mind. I thought it might be useful to open

A Surfeit of Silliness

Is the world getting crazier? It seems so, but maybe I’m just more aware of the silliness. Here are just a few of the outlandish things I’ve run across recently.

Horoscopes still appear regularly in newspapers. Over 90 percent of adults know their zodiac sign. It never occurs to some people to question whether horoscopes are

Barefoot In Sedona: Bogus Claims About Grounding Your Feet to Earth Promote Medical Pseudoscience

There is a website that reveals “The world’s most dangerous invention.” Care to speculate what that invention might be? I might have guessed nuclear weapons.
