The featured speaker at this year’s National Science Teacher Association conference in Boston is…Mayim Bialik.

The lucky ones among you are saying right now, “who?”. Others may know her from her television work, but maybe don’t know the full story behind her ‘science’ activism.

She’s an actor who plays Sheldon’s girlfriend on Big Bang Theory. Right there, as far as I’m concerned, we have a major strike against her: I detest that show. It’s the equivalent of a minstrel show for scientists, where scientists are portrayed as gross caricatures of the real thing — socially inept, egotistical jerks who think rattling off an equation is a sign of intelligence. I think it’s literally an anti-science communication show. Who in their right mind would want to be anything like Sheldon, the narcissistic nerd? Who would want to work with people like that? The message it’s sending instead is that if you are a superficial asshole, you should become a scientist, where you will be loved for personality traits that would get you shunned in civilized company. (We also see the same phenomenon in atheism, where so many people think it’s a great excuse to be the insensitive Vulcan.)

But OK, that’s a matter of taste, I will admit, and maybe not enough of a reason to be appalled to think she is going to be speaking to science teachers (although it’s enough for me). And she does have a Ph.D. in neuroscience, you have to respect that.

But…

Mayim Bialik does not vaccinate her kids. She’s the spokesperson for the Holistic Moms Network. I know what you’re thinking: “holistic” doesn’t sound so bad. But take it away, Orac!

Just one look at its advisory board should tell you all you need to know. For instance, there’s Dr. Lauren Feder, who bills herself as specializing in “primary care medicine, pediatrics and homeopathy” and has been a frequent contributor to that bastion of quackery and antivaccine looniness, Mothering Magazine, where she recommended homeopathic remedies to treat whooping cough. It doesn’t get much quackier than that. But Feder is just the beginning. Also on the Holistic Moms advisory board is the grand dame of the antivaccine movement herself, the woman who arguably more than anyone else is responsible for starting the most recent iteration of the antivaccine movement in the U.S. Yes, I’m talking about Barbara Loe Fisher, the founder and president of the National Vaccine Information Center (NVIC), a bastion of antivaccine propaganda since the 1980s. She’s not the only antivaccine activist on the advisory board, though. There’s also Peggy O’Mara, publisher of Mothering Magazine and Sherri Tenpenny, who is described right on the Holistic Moms website as, “one of America’s most knowledgeable and outspoken physicians, warning against the negative impact of vaccines on health.” Then there’s Dr. Lawrence Rosen, “integrative” pediatrician who appeared at the NVIC “vaccine safety conference” back in 2009 with Barbara Loe Fisher and Andrew Wakefield. In fact, Barbara Loe Fisher, Sherri Tenpenny, and Lauren Feder are featured very prominently on the Holistic Moms Network page on vaccination. But that’s not all. If there’s one more thing that should tell you all you need to know about the Holistic Moms Network approach to science-based medicine, then take a look at its sponsors: Boiron (manufacturer of the homeopathic remedy for flu known as Oscillococcinum), the Center for Homeopathic Education (and I bet it is homeopathic too), the National Center for Homeopathy, and a whole bunch of other purveyors of woo and quackery.

And he has a lot more to say, as usual.

So why is this woo-peddling, vaccination-denying sitcom star being featured as a speaker at NSTA? I don’t know. Because she has a Ph.D. and pretends to be socially inept on TV? That doesn’t seem to be a good reason. Will Jenny McCarthy be invited to deliver a keynote next year? How about Ken Ham — he’s very into ‘science’ education, you know. Gosh, if we’re going to open the door to quacks, the pool of potential speakers just expanded immensely! Joseph Mercola? Andrew Weil? Deepak Chopra!

Tsk, NSTA. Do you vet your speakers at all?
