The rise of the alt-right and white nationalist movements in the U.S. contributed to a resurgence of eugenics and race science in academic literature. Private donors began funding race science, and proponents of scientific racism started manipulating the push to make science more public.

Even well-intentioned scientists have been involved in this shift by promoting genetic determinism, the idea that genes are the primary driver of traits and behaviors. Problematic work has been platformed in the name of academic freedom, further fueling the resurgence of eugenics.

Paul Lombardo, a professor of law at Georgia State University, who has extensively studied the legacy of eugenics, expressed his surprise at how eugenic thinking has become more overt in recent times. The language used by proponents of eugenics is no longer subtle, with direct references to genetic superiority and inferiority.

Shannon O’Brien, a political scientist at the University of Texas, Austin, who has written a book on eugenics in American politics, highlighted the dangerous nature of eugenicists. They not only harbor hatred for others based on ethnicity or skin color but also believe in legislating people out of existence through measures like sterilization and extermination.

Former President Donald Trump’s rhetoric and embrace of eugenic thinking have not received enough attention, according to experts. Trump has made statements suggesting that certain people are genetically superior, rooted in the idea of “racehorse theory” that he was introduced to by his father. His views on genetics and intelligence perpetuate dangerous eugenic ideologies.

The history of eugenics dates back to Francis Galton in the late 19th century, who applied Charles Darwin’s theory of evolution to humans. The field of eugenics gained traction in the U.S., leading to policies like selective breeding and forced sterilization. The sequencing of the human genome in the 1990s reignited interest in eugenics, with the belief that genes could explain complex behaviors.

The Human Genome Project aimed to dispel notions of genetic differences between groups but inadvertently fueled genetic determinism. Geneticists hyped up the role of genes in people’s lives, focusing on the 0.1% of genetic variation that makes us different rather than the 99.9% that makes us the same. Companies like 23andMe and Ancestry.com further promoted genetic determinism by linking genetics to health and racial identity.

In the early 2010s, mainstream academic circles began discussing ideas of genetic intelligence and racial biology, reflecting a shift towards eugenic ideologies. The resurgence of eugenics and race science in the U.S. poses a significant threat, with dangerous implications for marginalized communities.

Ultimately, the legacy of ideas like Richard Lynn’s and the differential K theory highlight the dangers of using flawed research to perpetuate harmful stereotypes and discriminatory practices. It is crucial for researchers to critically examine their work and consider the broader implications of their findings. By challenging and rejecting pseudoscientific theories that seek to justify inequality based on race or ethnicity, we can work towards a more just and equitable society for all.

In recent years, there has been a shift in the understanding of genetics and its role in shaping human abilities and behaviors. Researchers like Panofsky have introduced paradigms that challenge the notion that genes are the sole determinants of our traits. Instead, they suggest that genes interact with a multitude of other factors to influence who we are.

This new perspective opens up a door to a post-deterministic biology and genetics. It implies that our genetic makeup is not the sole dictator of our destiny, but rather a player in a complex web of influences. This paradigm shift has the potential to revolutionize the way we think about genetics and human potential.

However, despite these advancements, the field of genetics has been slow to fully embrace this new way of thinking. The traditional belief that genes are central to our abilities and behaviors still prevails in many circles. This outdated mindset can inadvertently perpetuate harmful rhetoric, such as the type used by Trump to stigmatize immigrants.

The echoes of eugenics, a dark chapter in American history, still linger in our society. Just over a century ago, eugenicists like Harry Laughlin used pseudo-scientific theories to justify discriminatory policies against certain groups, including immigrants. His belief that a person’s “blood” or hereditary qualities determine their worth is disturbingly similar to the rhetoric we hear today.

Despite efforts to distance ourselves from this shameful past, the underlying ideas of eugenics continue to influence our perceptions and policies. Michele Goodwin, a professor of constitutional law, warns that we cannot afford to be complacent in assuming that we have eradicated these harmful beliefs from our society.

As we navigate the complexities of genetics and human diversity, it is crucial that we confront the legacy of eugenics and challenge the outdated beliefs that still linger. By embracing a more nuanced understanding of genetics and human potential, we can move towards a more inclusive and equitable future for all.
