Be afraid of fear, not personal genomics.

It’s just the way it is now. This headline. This story.

It follows the recipe. (1) Start with a headline that demonstrates controversy. (2) Present a story about science-related news (which does not require controversy to be news). (3) End it ever-so briefly and vaguely with dissent, doubt, outcry or warning. 

This recipe applied to personal genomics is particularly bad.

If you read or hear that story you might be primed before you start to wonder, okay what’s the worry? Glad this article will tell me, finally, what we should be concerned about concerning this brave new world of personal genomics.

But you’ll be sorry when you reach the end and this is all you get:

But the idea of widespread sequencing is setting off alarm bells. How accurate are the results? How good are doctors at interpreting the results, which are often complicated and fuzzy? How well can they explain the subtleties to patients? The fear is that a lot of people could end up getting totally freaked out for no reason. And there are concerns about privacy. Scientists recently even sequenced a fetus in the womb, raising the possibility of everyone getting sequenced before or at birth — a prospect with a whole new set of questions and concerns. “I think there are lots of populationwide and individual dangers,” said Mark Rothstein, a bioethicist at the University of Louisville. “We’re basically not ready for a society in which very exquisite, detailed genomic information about every individual, potentially, is out there.”

Why? Tell us? And I don’t mean the “us” who have access to the academic journals. Or the “us” who have the patience to bushwhack through the jargon. I mean, here is your chance to share with the public who you’re concerned about: Since you brought it up, tell us why we should worry.

It’s unclear who deserves the complaints and the criticism for producing pieces like this, since much of the “telling us” that I’m begging for might be lying on the cutting room floor.

I’m clenched about this because right now about 20 students in my Human Varition (Anthropology 350) course at the University of Rhode Island are voluntarily participating in genotyping through 23andMe. And I’m using this curriculum for the second semester now. After last spring, where over 100 students in both Human Variation and also the introductory level Human Origins (Anthropology 201) did 23andMe, not one student got “totally freaked out.” This along with much of my experience with genotyping and undergraduates indicates that, with education and with understanding, personal genomics does not induce fear. Not coincidentally, participating in personal genomics aides in education.

And the same fear that I’m trying to mitigate through education is the same fear that some journalists and ethicists seem to be perpetuating if not creating.

In my experience, if you’re informed, you’re likely to appreciate biological complexity rather than cling to genetic determinism. If you’re informed, you understand the positive and negative consequences and aspects of personal genomics. If you’re informed, you don’t get lured into personal genomics for all the wrong reasons. You don’t order an expensive 23andMe spit kit as if it’s snake oil. You don’t send your vial of saliva to California, along with 300 of your precious bucks, because you think it will help you to live a longer, healthier life, or because you think it will show you your future.  Spit kits are not crystal balls, are not medicine, are not cures. Plus, the results will also most certainly change! Not your genotypes, but how they’re interpreted. That genomes must even be “interpreted” should be a flag shouldn’t it?

Informed citizens and consumers don’t buy into personal genomics thinking it’s their one and only answer– their key to “me”– because “me” will be increasingly different the more we learn about genetics and the links between genotypes and phenotypes. “Me” is, for most, too stubborn and conservative, while at once too big and too free, to be dictated by genotypes and probabilistic phenotypes.

All that is guaranteed with a 23andMe spit kit is that you will see parts of yourself that you haven’t seen before. There’s not a whole lot on the planet that’s cooler than that. For most of us who will never go to Mars, at least we’ve got this, at least we’ve got innerspace.

Even if you don’t get an ounce of joy from the experience, when you’re informed you don’t fall uncritically for claims that spit kits are dangerous or venomous.

Considering the engaging educational opportunites provided by personal genomics, considering its power to inform, spit kits may just be much-needed anti-venom.

In my experience education diminishes fear about genetic determinism because it diminishes genetic determinism. That leads me to see fear of personal genomics as a symptom of ignorance. And that’s something worth being afraid of.

Note: Ken, Anne and I have differing views on direct-to-consumer (DTC) personal genomics like 23andMe so please remember that I speak only for myself when I write. Also, I am not paid  or sponsored by 23andMe to endorse their product. I use their product, at the educational rate, to teach anthropology at the University of Rhode Island.
