Hey, all! The JREF announced yesterday the publication of a new critical thinking resource in the form of "Magic in the Classroom - Using Extraordinary Claims to Teach Critical Thinking," a FREE e-book.JREF eBookJREF eBook

It can be enjoyed by laypeople, but we're hoping it will also be picked up by educators and utilized in the classroom to encourage critical thinking. This book is the culmination of work by a dozen educators from numerous disciplines; I'm proud to say that three of the chapters are from me!

Here's a good piece on Bay Area vaccination statistics, from this morning's SF Chronicle.Mom & BabyMom & Baby

One of the few articles I've seen that explores the nuances of refusal -- it goes beyond "gee, unvaccinating parents are all ignorant/selfish/health nut/California hippies/[insert pejorative of choice here]".

I've always thought that for very many non-vaccinators, the main motivator was fear for the health/comfort of the child, and concern about the number and scheduling of vaccinations, rather than "vaccines are poison" mentality. That is a catchier meme for the press, though, and gets more eyeballs.

Plus, few articles explore under vaccination, which doesn't necessarily rest with an ideological objection to vaccination and can be just that busy parents don't get around to the full sequence, second innoculation, etc.

One of the most annoying parts of the "world of woo" is people who claim to have psychic powers. Although none has ever actually shown evidence of this ability under strict observation, it's a multi-million dollar business, with some in the field becoming quite prominent. Chip Coffey may not be one of the biggest players, but he's had his 15 minutes of fame with A&E's "Psychic Kids" program and a few other television appearances.

So after a lot of work and planning, we did just that.

Earlier this month, I got a message from my friend, the filmmaker Tyler Meason, letting me know that he’d be in San Francisco on Sunday, June 15th for the screening of “An Honest Liar,” the documentary he co-created with Justin Weinstein that chronicles the life of world-renowned magician and skeptic, James “The Amazing” Randi. I purchased tickets and said that I would see him there. A few weeks passed, and I got another message from Tyler, this time letting me know that James Randi himself would be attending the screening, and suggesting that I look into asking him to make an appearance for the Bay Area Skeptics.

Excited about the possibility, I was eventually able to contact Randi’s husband, the artist Deyvi Peña. As it turns out, Randi was delighted by the invitation, and agreed to show up to an informal meet-and-greet the day before the screening. I explained that this wou

Jon CarrollJon CarrollJon Carroll understands, promotes, and appreciates science, which we in the Bay Area can be grateful for. CLICK HERE to read Jon's excellent article in the SF Gate, "OMG, What Is In Your Drinking Water."

In this column he nails a Portland official for ridiculously draining 38 million gallons of water because someone allegedly urinated in it. That's 3 parts/billion: a lower level than permitted for arsenic. But read the rest of the article for a very satisfying description of how science works, why it's important to pay attention to it, and why "science is a linchpin of modern society". I sure wish he'd be willing to speak some year for SkeptiCal. (And do you have your ticket yet?)

In my latest article on James Randi's "Swift" blog, I investigate some helpful tips from social science research that, if applied, can make your days a bit merrier and brighter.

After bringing home their colorful, sugar-laden bounty from a successful night of Trick or Treat, millions of AmericanHappy HalloweenHappy Halloween children will spend the coming weeks locked in a battle of wills with their parents over how much of the spoils they are allowed to enjoy, and how often they'll have access to it. One of the most common strategies parents employ, based upon a supposed connection between sugar and hyperactivity, will ensure that parents lose that battle...at least, in a scientific sense.

When kids are “bouncing off the walls,” it's not uncommon to hear parents call a temporary halt to all sugar consumption in an effort to save their sanity. One of the most pervasive myths in parenting, the belief that sugar promotes hyperactivity, this connection is solidified in the minds of millions of parents (Ghanizadeh & Zarei, 2010), reinforced at Halloween by one of the most persuasive types of evidence: their own children’s behavior. But, as we skeptics know, personal experience isn’t always the best indicator of reality. Let’s take a

Although most people can provide you with scarcely more detail about the human brain than its existence and approximate location, one Left-Brained / Right-BrainedLeft-Brained / Right-Brainedof the most popular brain-related facts they often report with great certainty is that they are either Left- or Right-Brained. More specifically, "Left-Brained" people describe themselves analytical and logical, with a penchant for mathematics, while the "Right-Brained" report being creative and emotive, with more artistic and intuitive personalities. These self-reports are fraught with problems…not the least of which is the fact that the entire notion of “Left-Brained” or “Right-Brained” people is complete bunk.

A quick Internet search for “Left-Brain/Right-Brain” tests results in literally thousands of options. A popular gimmick for team-building exercises and introductory psychology classes since at least the 1960s, these introspective measures almost always result in a personality type that the participant agrees with.

Sheldon HelmsSheldon Helms, a BAS Board Member, was featured at a gathering of the Atheist Alliance of San Francisco. The presentation title:
Gay Conversion Therapy: You Make Me Sick.

As our country deals the issues of Marriage Equality, gays in the military, and other forms of inclusion of gays and lesbians into mainstream society, and as Russia and others institute draconian laws limiting the rights of their gay and lesbian citizens, fringe religious and therapeutic organizations have operated mostly in the shadows, attempting to "convert" their homosexual clients to heterosexuality through a mixture of prayer and pseudoscience.

Helms describes the history of attempts to define homosexuality as an illness and to make gays go straight. He details such aspects as: the goals and viewpoints of those involved in Gay Conversion Therapy; their pseudoscientific and sometimes dangerous practices; and a description of the results of over 100 years of attempts to alter sexual orientation.

Some forms of Gay Conversion Therapy have been outlawed in California and New Jersey, and one of the primary institutions that
