Which biotech foods are most acceptable to the public?

That's the title of a paper I just published in the Biotechnology Journal with Brandon McFadden and Brad Rickard.  

Based on a survey of over 1,000 US consumers, we sought to determine which types of foods or biotechnology applications might be most acceptable.  

Respondents were asked, on a 7-point scale, to indicate how desirable (i.e., 1 = very undesirable to 7 = very desirable) it would be to eat six foods strategically selected to vary by product type (i.e., apple, corn, and beef) and degree of processing (i.e., fresh and processed): apples, apple juice, corn on the cob, corn chips, beef steak, and beef hotdog. The question was then repeated except each food was identified as being GE: genetically engineered apple, apple juice made from genetically engineered apples, etc. Of interest is the change in the desirability of each food product as it moves from a GE to a non-GE form, and whether the change in desirability systematically relates to product type and degree or processing. 

Here's what we found.

We write:

when foods were not GE, fresh was preferred over processed and beef products were preferred over corn and apple products. . . . [W]hen products were GE, respondents continued to prefer fresh to processed (although not nearly as much as when non-GE), but now respondents prefer corn and apples to beef, indicating a preference reversal. . . . The results indicate that adding “GE” causes a larger drop in desirability for fresh than processed food and also caused a larger drop in the desirability of meat relative to corn and apples. Thus, not only does GE change the overall desirability . . . , it changes the relative ranking of products, with larger penalties associated with being GE assigned to fresh food and meat.

We also asked consumers how desirable or undesirable different reasons for genetic modification were.  All the reasons had a mean score above 4 (on a scale of 1 to 7), meaning they were more desirable than not.  Here the results for each issue.

How effective is education at correcting misperceptions

Whether its GMOs or pesticides or economic effects of various food policies, it seems that the public often holds beliefs that are at odds with what the experts believe.  A natural tendency - especially for someone who is an educator - it to propose that we need more education on these topics.

But, how effective are we at changing people's minds?  This article in Pacific Standard by the psychologist David Dunning might give us pause.  

The research suggests:

What’s curious is that, in many cases, incompetence does not leave people disoriented, perplexed, or cautious. Instead, the incompetent are often blessed with an inappropriate confidence, buoyed by something that feels to them like knowledge.

But, before you start feeling too confident in your own abilities, read the following:

An ignorant mind is precisely not a spotless, empty vessel, but one that’s filled with the clutter of irrelevant or misleading life experiences, theories, facts, intuitions, strategies, algorithms, heuristics, metaphors, and hunches that regrettably have the look and feel of useful and accurate knowledge. This clutter is an unfortunate by-product of one of our greatest strengths as a species. We are unbridled pattern recognizers and profligate theorizers. Often, our theories are good enough to get us through the day, or at least to an age when we can procreate. But our genius for creative storytelling, combined with our inability to detect our own ignorance, can sometimes lead to situations that are embarrassing, unfortunate, or downright dangerous—especially in a technologically advanced, complex democratic society that occasionally invests mistaken popular beliefs with immense destructive power (See: crisis, financial; war, Iraq). As the humorist Josh Billings once put it, “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.” (Ironically, one thing many people “know” about this quote is that it was first uttered by Mark Twain or Will Rogers—which just ain’t so.)

Several studies seem to suggest that providing people with a little information may not lead to more agreement on an issue, but rather can result in polarizing opinions. The reason is that information makes use feel more informed, and lets us feel more confident in whatever our political or cultural tendencies would lead us to believe in the first place.  That is, people bend information to reinforce their identity and cultural beliefs. 

Frankenfood

Buried in the comments section of an article in the Guardian about a UK retailer selling some American brands that contain GMOs was this comment that made me laugh:

It should be noted that Frankenstein was not even a hybrid, let alone a gmo. He was a grafted individual, much like today’s grapevines in vineyards and apple trees.

GMO and Soda Votes

I have been keeping an eye on several ballot initiatives in yesterday's election.  Not all results are finalized, but here's what we know so far:

In Colorado, mandatory GMO labeling was defeated by a wide margin, 66% to 34%, with 93% of precincts reporting.

In Oregon, mandatory GMO labeling is very close and still up in the air.  With 88% of the votes counted, the "No's" are ahead by about 26,000 votes (659,404 to 633,132), giving the "No's" a current 51% to 49% margin. 

A vote in Maui, HI to ban cultivation of GMOs is too close to call

Berkeley, CA passed a soda tax (75% in favor vs. 25% opposed)

The majority of voters in San Francisco, CA favored a soda tax (55% in favor), but the initiative required a 2/3 majority to pass. Thus, the soda tax failed in San Francisco.
