Quick takeaways
Heliospect Genomics allows wealthy parents to screen embryos for intelligence, raising significant ethical concerns about genetic enhancement and potential eugenics.
The scientific basis behind the company's claims about increasing IQ through embryo selection is questionable, highlighting the complexities and multifactorial nature of intelligence.
Deep dives
Emergence of Genetic Screening Technology
A US tech startup, Heliospect Genomics, proposes a controversial genetic screening service that allows prospective parents to select embryos based on various traits, including intelligence and physical attributes. Unlike traditional IVF clinics, Heliospect functions as a tech company, analyzing genetic data to provide predictions about the future children’s traits. Their pitch includes the ability to screen up to 100 embryos for a cost of $50,000, suggesting that parents could choose embryos based on desired characteristics like IQ. This service, however, raises ethical questions, particularly since it is not legally offered in places like the UK, highlighting the disparity in genetic selection practices across regions.
Genetic Predictions and Their Limitations
Despite the claims made by Heliospect regarding the potential for selecting embryos that could lead to higher IQs, the scientific validity of these predictions is questionable. Experts emphasize the complexity of intelligence, which is influenced by a multitude of genes and environmental factors, making it difficult to accurately pinpoint how many genes contribute to cognitive abilities. The company suggests that selecting the smartest of ten embryos could yield an average IQ gain of over six points, a claim that lacks substantial scientific backing. This raises concerns as to whether such marginal gains justify the risks and ethical implications of undergoing extensive IVF cycles.
Ethical Implications of Genetic Selection
The use of technologies like embryo selection brings forth significant ethical concerns, particularly relating to societal perceptions of genetic superiority. Critics warn that this could lead to a normalization of eugenics, where certain genetic traits are deemed superior, which contrasts starkly with the complexities of human intelligence and value. By facilitating genetic selection for traits like intelligence, there is fear of inadvertently reinforcing social inequalities based on biology rather than on environmental factors. The debate is further complicated by the realization that selective breeding in other species has led to unintended negative consequences, emphasizing the need for careful consideration and public discourse surrounding such technologies.
A startup company, Heliospect Genomics, is offering to help wealthy couples screen their embryos for IQ using controversial technology that raises questions about the ethics of genetic enhancement. Science correspondent Hannah Devlin tells Madeleine Finlay about the joint investigation into the company by the Guardian and the campaign group Hope Not Hate.
