The Evolutionary Perspective on Gender DifferencesAccording to evolutionary psychologist Steve Stewart-Williams, almost everyone gets sex wrong. Traditionalists tend to exaggerate natural differences between men and women, while progressives tend to minimize them and assume that nurture and socialization play a decisive role. In his book "A Billion Years of Sex Differences," Stewart-Williams promotes a more nuanced, scientifically rigorous public conversation about why and how men and women differ to guide better policymaking.Understanding the Spectrum of Sex DifferencesStewart-Williams identifies varying degrees of sex differences. Some are relatively pronounced, such as attraction patterns, upper body strength, height, likelihood of committing violence, and occupational interests. Others, like ability in mathematics or conscientiousness, are much more modest. These differences are best visualized as two overlapping bell curves. For example, while the average man is taller than the average woman, there is considerable common ground—knowing someone is 5ft 8in doesn't enable confident gender identification.Research Evidence and Scientific BiasesAs a professor of psychology at the University of Nottingham Malaysia, Stewart-Williams examines various physical, psychological, and cognitive sex differences through an evolutionary lens. He identifies common biases in his field, including "gamma bias" (minimizing differences that paint men in a better light while highlighting those that do the opposite) and "delta bias" (an aversion to traditional sex differences and a preference for the reverse).His research found that when presented with fictitious studies showing men drawing better, lying less, or being more intelligent, people rated them as lower in quality, more harmful, and more worthy of censorship than studies showing women possessed these positive traits.Implications for Gender Equality and PolicyStewart-Williams argues that innate differences don't imply one sex is better than the other, nor do they suggest a moral imperative to enforce sex differences. However, he believes that when given freedom of choice, men and women tend to gravitate toward different directions—men toward working with things and status, women toward working with people and relationships.Interestingly, various studies find that many sex differences—from occupational preference to personality traits—are more pronounced in more gender-equal countries, suggesting that when social constraints are removed, natural tendencies become more evident.The Future of Gender ResearchWhile Stewart-Williams presents compelling evolutionary explanations for sex differences, the reviewer notes that evolutionary psychology isn't always the most useful lens. For example, understanding domestic violence as primarily a manifestation of male aggression rather than patriarchy may overlook how socialization and culture shape behavior in different societies.The book contributes valuable insights to the nature versus nurture debate, but ultimately represents only one part of a complex story about human development and gender relations. Future research will likely need to integrate biological, psychological, and sociological perspectives to fully understand the intricate interplay of factors that shape who we are.

The Growing Concern Over AI's Economic ImpactOne in three university students in Great Britain believe that artificial intelligence will eliminate jobs so rapidly that it will trigger civil unrest, according to a new survey by King's College London (KCL). This significant finding highlights the deep concerns among educated young people about the potential societal consequences of rapid technological advancement.The poll, conducted by the King's Institute for Artificial Intelligence and the KCL Policy Institute, represents the first major tracking study of attitudes toward AI across different segments of British society. It compares responses from university students, young people aged 16 to 29, employers, and the general public.Student Usage Patterns and PessimismUniversity students emerge as among the heaviest users of AI technology, with 77% reporting using it at least a few times a month—substantially higher than the 46% of workers who do so. Additionally, 27% of students use AI daily or almost daily, indicating deep integration of these tools into academic life.Despite their familiarity with AI, students express significant pessimism about its economic consequences. More than half are convinced that job losses resulting from AI will be more severe than those in a typical recession. This pessimism is particularly notable given that students generally hold more positive views about AI's overall impact on humanity compared to the general public.Key Statistics from the AI Attitudes Survey34% of university students believe AI will eliminate jobs fast enough to cause civil unrest (compared to 22% of the general public)77% of university students use AI at least a few times a month (compared to 46% of workers)27% of university students use AI daily or almost daily52% of male university students believe AI is positive for humanity (compared to 24% of the general public)9 out of 10 university students have encountered problems with AI, most commonly factual errors (37%) and made-up sources (31%)78% of students would still choose to attend university, though 30% would have selected a different subjectImplications for Education and the WorkforceThe survey reveals a significant gap between students' perceptions of their preparedness for an AI-shaped job market and their actual experiences. While 60% believe universities are capable of preparing them for this future, only 36% report actually receiving adequate preparation.This disconnect suggests that educational institutions may be struggling to adapt curricula and teaching methods to address the rapidly evolving technological landscape. The findings also highlight gender differences in how students perceive AI's impact on their cognitive abilities, with male students more likely to believe AI enhances their thinking skills while female students tend to hold the opposite view.Divergent Views on AI's FutureThe poll captures contrasting perspectives on AI's potential impact. Bobby Duffy, director of the KCL Policy Institute, emphasizes the widespread concern about AI's effect on employment, particularly at entry-level positions, and its broader implications for young people and the economy.In contrast, Bouke Klein Teeselink, a lecturer in philosophy, politics, and economics at KCL, offers a more optimistic outlook. He suggests that with appropriate training, policies, and institutional support, AI could lead to increased productivity, expanded opportunities, higher incomes, and accelerated scientific progress.These divergent views reflect the broader societal debate about artificial intelligence—balancing legitimate concerns about displacement and inequality against the potential benefits of technological advancement.
