Explaining public opposition to GMOs
Concerns about health, environmental, and socioeconomic hazards have resulted in a strong public opposition to GMOs 1, 2, 3. These worries tend to have a large impact on national and international policies. For instance, in India, the government suspended the culture of Bacillus thuringiensis-engineered Solanum melongena (Bt brinjal), despite initial approval for commercialization [4]. In Europe, the lack of public support for GMOs has led to a de facto moratorium within the EU on new GM crops
An intuitive understanding of GMOs
Although generally we feel as if we control willfully what we think and do, much of our thinking depends on intuitions, of which the working largely stays below the radar of conscious awareness [14]. Among other things, these intuitions, which evolved in response to particular adaptive situations, automatically shape expectations about the world or induce reflexive risk assessments [15]. Under ecologically relevant conditions, these intuitions tend to generate rational responses [16] but, when
Folk biology
The human mind intuitively understands how the biological world functions. One constituent of this folk biology is psychological essentialism [25] that amounts to the belief that organisms hold an unobservable, immutable core determining their identity and, thus, their development and behavior. Psychological essentialism makes sense evolutionarily because it allows individuals to categorize automatically the biological world. As such, valuable information becomes immediately available, enabling
How the opposition to GMOs does – and does not – take shape
Some representations are more popular than others. The popularity of a representation is determined by the relevance of the information it purveys. Whether information is relevant depends on its ability to capture attention and the ease by which the mind can process it. The more information is in line with our intuitive expectations, the more easily it is apprehended, remembered, and, thus, communicated. Because intuitions are universally shared, appropriate representations stand a greater
Concluding remarks and implications
The human mind comprises evolved intuitions that shape and constrain cultural preferences. In the case of GMOs, folk biology, religious intuitions, and emotions such as disgust leave the mind readily seduced by representations of GMOs as abnormal or toxic. By pointing out how public aversion to GMOs thrives on such preferences, it is understandable why people continue to resort systematically to concerns about GMOs that are scientifically unsubstantiated. With such a perspective that is not
