GMO and Dunning Kruger

Published by under Skepticism,Technology

GMO-surveyIncreasingly in modern society, with perpetual access to the internet, lack of information is far less of a problem than misleading or incorrect information. As Dunning (of Dunning-Kruger fame) noted:

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.

I would add to that list – deliberate propaganda. People can feel as if they are well-informed because their heads are full of nothing but propaganda. Just have a conversation with an anti-vaxer, creationist, or flat-earther and you will see. Lack of information is not their primary problem.

Attitudes toward GMOs are also largely a function of information vs misinformation. After two decades of a dedicated anti-GMO campaign by the organic food lobby and Greenpeace, the public is largely misinformed about GMOs and organic food. This has led to a 51 point gap (the largest of any topic covered) between what scientists believe about GMOs and what the public believes.

Michigan State University has recently published their Food Literacy and Engagement Poll which sheds further light on this issue. For example, 20% of respondents believe they rarely or never consume food with GMOs and another 26% did not know. Meanwhile, 75-80% of packaged food contains GMO ingredients. Most corn and sugar derives from GMO crops. There are also “hidden” GMOs. For example, just about all cheese is produced with enzymes (rennet) derived from GMO yeast. Laws requiring GMO labeling or outright banning GMOs, however, always carve out an exception for cheese, because the cheese industry would essentially not exist without it.

Questions on GMOs

Published by under Technology

gmo-cartoons-good-fat-100Genetically Modified Organisms (GMOs) remain the one issue on which there is the greatest disparity of opinions between scientists and the general public. Even among self-identified skeptics, people who make a genuine effort to align their opinions with the scientific evidence, there remains great distrust of GMOs and the companies who produce them (such as Monsanto).

This disparity is partly due to the decades-long campaign by Greenpeace and the organic lobby to demonize GMOs. It is much easier to fearmonger than to reassure. I think we have started to crawl back toward reality on this issue, but we have a long way to go. We started with the low-hanging fruit, correcting the outright lies.

It is much more difficult to dispel the vague sense that there is something menacing about GMOs. We have a deep emotional connection to food that we perhaps don’t even recognize. It is easy to trigger our emotion of disgust, and we have apparently evolved to err on the side of avoiding anything that may be tainted. The image of unnatural “frankenfood” still clings to our culture and is hard to dispel.

Aspartame and GMOs

aspartameStories take on a life of their own. That is the origin of urban legends, myths, and even religion. A good narrative feeds on itself and can be self-sustaining. It evolves and adapts and finds fertile ground in most human hosts (unless they have been inoculated with a sufficient dedication to facts and logic).

Aspartame, an artificial sweetener that was approved by the FDA in 1981, has been the focus of conspiracy theories ever since. The “holistic medicine” and “natural health” subcultures have largely been responsible for spreading misinformed hysteria about aspartame, first through chain letters and newsletters, and now through the internet.

Ever adapting, they have added some new wrinkles to the legend of aspartame, making sure that their baseless fearmongering is making use of the latest buzzwords.

Aspartame is Safe

First for some background, the anti-aspartame brigade claims that this food additive has been linked to cancer, neurological disorders, and a long list of complaints and diseases. They are simply lying, or the equivalent of lying by cherry picking data, dismissing evidence out-of-hand, and making up whatever claims they need to support their position. Continue Reading »

One more round with Massimo on GMOs and Skepticism

platoLast week I wrote a response to a NYT article on GMOs. Massimo Pigliucci wrote a critical analysis of my response. I then responded to that piece.
Below is the final round of responses on this issue, one from Massimo and then a final response from me. In this round Massimo changes the focus from GMOs specifically to how the skeptical movement handles such issues.


My (further) response to Novella on GMOs

by Massimo Pigliucci

I promise, this is the last round concerning this particular discussion, at the least on my part. To recap: Danny Hakim, an investigative reporter for the New York Times, published a critical piece on certain aspects of GMO technology; my friend and fellow skeptic Steve Novella responded; I commented critically on Steve’s response; and he responded to my criticism. The current post, however, isn’t going to be yet another blow-by-blow affair, for a few reasons: i) it would be even longer than the last installment, which I fear would severely test readers’ patience; ii) there is a diminishing return to going deeper and deeper and insert more and more qualifications to any argument; and iii) it seems to me that most of what Steve and I wanted to say has been said already.

So let me try to zoom the discussion out a little, shifting attention to what I think are some background issues of which this exchange has been a particular instantiation.

Massimo Pigliucci Responds on GMOs

Published by under Skepticism,Technology

Scientists examining crops in field

I always enjoy when someone whom I respect and who cares about using careful and valid arguments disagrees with me. It is an opportunity for me to correct any mistakes I have made, to deepen my understanding of the topic, or at least tighten up my arguments.

Last week I wrote an article responding to a recent New York Times piece on GMOs (genetically modified organisms). Massimo Pigliucci, who is a friend and skeptical colleague, disagrees with my analysis. Massimo thinks that knee-jerk defense of GMOs is a problem generally in the skeptical movement, and uses me as an example. I disagree with him, but will discuss that toward the end.

I want to take the points that I make in my previous post one by one and see how they hold up to Massimo’s criticism, and may expand upon them and include other comments as well.

GMOs should not be considered as one thing.

I wrote in my previous article:

“Any meaningful analysis of GM technology has to consider each application unto itself. Further, the GM trait is only part of the picture – you also have to consider how it is being applied.”

I have consistently taken this position in my writings, and this is also the most common position I encounter when reading other skeptics writing about GMOs. It is not really meaningful to consider GMOs as if they are one thing, and this is a mistake that Hakim makes in the original NYT article.

The Times Gets it Wrong on GMOs

Published by under General Science

Bt BringalIt is unfortunate that so many journalists begin with a narrative and then back fill the facts and points necessary to tell their narrative. I have encountered this many times when being interviewed for an article or documentary – more often than not the reporter or producer is simply hunting for quotes to plug into a story they have already written. I am not giving them information so much as filling a role, which could be that of expert or of token skeptic.

We are all familiar with this phenomenon when reading about political topics in outlets that have a clear editorial policy. If the policy is clear, we don’t even expect objectivity. When reading about non-political topics, however, I do think there is a general expectation of objectivity, but the motivated reasoning can be just as pronounced.

A recent New York Times article, in my opinion, is a good example of what happens when a journalist writes about a complex and contentious topic and allows their narrative to overtake the facts. The article, Doubts About the Promised Bounty of Genetically Modified Crops, declares the narrative in the headline (yes, I know journalists don’t write their own headlines, but they still may accurately reflect the tone of the article, as in this case).

GMOs and Horizontal Gene Transfer

Published by under General Science

horizontal-gene-transferPeople reject genetically modified organisms as food (GMOs) for a variety of reasons, but the single most cited reason is the false belief that they are unhealthy. That specific belief also represents the single greatest disconnect between the opinion of scientists and of the general public in a 2015 Pew poll, greater than evolution, climate change, or vaccine safety.

The reason for this disconnect is that the public is relying upon their intuition, rather than scientific knowledge, to arrive at their conclusion. Further, that intuition has been hijacked by a deliberate anti-GMO campaign orchestrated by misguided environmentalists and by the organic food lobby to help promote their brand.

As Stefaan Blancke and his coauthors argue in the above article:

This intuitive reasoning includes folk biology, teleological and intentional intuitions and disgust.

One of the primary “folk biology” talking points of the anti-GMO crowd is that it is “unnatural” to place genes from one species into a distant species. No further reasoning is offered to defend this position – just the invocation of what is “natural” seems to be enough. Those who defend the scientific position often point out that this irrelevant, just a manifestation of the appeal to nature fallacy. Whether or not something occurs in nature does not determine if it is good or bad for human health.

Bt Brinjal – Destroying the Anti-GMO Narrative

Published by under Technology

Bt BringalIt is amazing how a rigid ideology can so dramatically alter one’s perception of reality and justify bad behavior. Consider the following summary of events:

One side of the GMO debate opposes the use of seeds that were created in the public interest and given freely to farmers, without any corporate ownership or profit motive. These plants dramatically reduce the use of pesticides and reduce loss due to pest damage.

The activists on this side don’t have any facts at all to back them up, so they willfully spread lies and misinformation, spread propaganda as if it were journalism, and make personal attacks against those on the other side. Yet, they still think they are the good guys.

The Anti-GMO Narrative

The anti-GMO narrative – and that is what it is, a story – has several consistent elements. According to this narrative GMOs are poisonous, bad for farmers, and solely promoted by companies out to make money by controlling the food source and exploiting farmers and the public. The problem with this cartoon is that it does not comport with reality.

Framing the Debate on GMOs

Framing is a very interesting and intellectually critical concept. It is part of metacognition, the act of stepping back from the details of your beliefs and arguments to think about the nature of the thinking itself. Framing is meta-debate, where you think about the context of the debate itself, not just the details.

Framing can also be used, either consciously or inadvertently, to control a debate or discussion, to set up the parameters so that they favor one position.

A recent article in The Conversation discusses the framing of the GMO (genetically modified organism) debate. It’s an interesting article that definitely makes me think about how the GMO discussion should be framed, although I do not agree with the author, Sarah Hartley’s, take.

Senate Passes GMO Labeling Compromise

“You’re unhappy. I’m unhappy too. Have you heard of Henry Clay? He was the Great Compromiser. A good compromise is when both parties are dissatisfied, and I think that’s what we have here.”

– Larry DavidGMO_labeling-thumb

Senate Democrats and Republicans have reached a compromise on the issue of mandatory GMO labels. I am not happy with the outcome, but it could have been worse. Apparently pro-labeling advocates are unhappy too.

Last year the House passed a bill that would preempt mandatory labels. That bill stated:

(Sec. 101) This bill amends the Federal Food, Drug, and Cosmetic Act to require the Food and Drug Administration (FDA) to continue the voluntary consultation process established under the FDA’s “Statement of Policy: Foods Derived from New Plant Varieties.” In that process, the FDA evaluates a scientific and regulatory assessment provided by the developer of a food produced from, containing, or consisting of a plant that is a genetically engineered organism (GMO).

The FDA may require a GMO food to have a label that informs consumers of a material difference between the GMO food and a comparable food if the disclosure is necessary to protect public health and safety or to prevent the label from being false or misleading. The use of a GMO does not, by itself, constitute a material difference.

This was a reasonable bill, which acknowledges that the way a food is produced saying nothing directly about the safety or other properties of the end product.  A GMO can be perfectly safe, and a non-GMO can be unsafe.
