How to Live a Life with More Positive Than Negative Feelings?

Decision-making is the cognitive process of choosing a preferred option from among a set of options (Wilson and Keil 2001). Decision-making is present through every aspect of life, and making good decisions for every important occasion during lifetime is a human being’s constant endeavor (Garnham 2016). Historically, religion and philosophy have been the only domains not only acting as gateways for explaining the meaning of life (McGhee 1992) but also acting as guidelines for facilitating and directing human important decisions during lifetime.

Darwinian evolution by natural selection is regarded as another gateway capable of explaining the existence and meaning of life (Dawkins 1986). Menelaos Apostolou, Assistant Professor at the University of Nicosia, in his book, Feeling Good: An Evolutionary Perspective on Life Choices, explores human decision-making from the perspective of Darwinian evolutionary science by addressing the question of how to live a life characterized by more positive than negative feelings.

The book begins by criticizing philosophy’s inability to direct humans toward a happy life, simply because philosophy has had very little knowledge on human nature and mind. Instead, Apostolou acknowledges the work of Darwin and Wallace and the subsequent advancement in understanding human nature done by evolutionary theory. In general, in this book he argues that based on genetic makeup and environmental conditions, individuals should make decisions in their daily life that increase the chance of survival and reproduction.

In the first chapter, Apostolou briefly and in a very simple language explains the origin  and evolution of life and the fundamental evolutionary forces. Then, he summarizes ….

Does ecology affect human behavior? Book Review

In their book The Parasite-Stress Theory of Values and Sociality, Randy Thornhill, Distinguished Professor at The University of New Mexico, and Corey L. Fincher, Assistant Professor at University of Warwick, present a new interpretation of human values and cultural behaviors, on the basis of ecological variations in parasite-stress prevalence across and within nations.

Before delineating their theory in upcoming chapters, in the second chapter Thornhill and Fincher discuss their philosophical viewpoints on scientific investigation in general, and evolutionary science in particular. First, the chapter compares philosophical and scientific methods of knowing, concerning exploration of the universe and its function. In particular, in this chapter the authors challenge philosophical aesthetics and argue that pure philosophical reasoning cannot discover causes of nature without scientific testing. The authors further argue that due to personal differences in values (biased common
sense, intuition, and emotional validation of ideas), human pure reasoning, thinking, and deduction are biased, and that aesthetic philosophy cannot empirically falsify or verify hypotheses. They also argue that all areas of science that deal with life and living beings are evolutionary in essence, and that humans are evolved animals and living beings—hence, that all studies of humans are evolutionary and biological studies. … Click here to read the rest.

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces

Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of men’s preferences. Using an average femininity preference for each country, we found men’s facial femininity preferences correlated positively with the health of the nation, which explained 50.4% of the variation among countries. The weakest preferences for femininity were found in Nepal and strongest in Japan. As high femininity in women is associated with lower success in competition for resources and lower dominance, it is possible that in harsher environments, men prefer cues to resource holding potential over high fecundity.

Why do we play? And why it is attractive?!

Question of the origin of play and playfulness has been one concern of Garry Chick, Professor at the Department of Recreation, Park and Tourism Management, Penn State University. From an evolutionary perspective, Professor Chick has developed a theory in which he explains adult play and playfulness. It is now known why children and offspring play and what the advantages of play would be in their adult life – they are mentally being prepared for the problems and conflicts that they might face in their adult life. But what is the advantage of play and playfulness in human adults?

Professor Chick has proposed that “both male and female adult humans prefer mates who are playful because playfulness signals desirable attributes in possible mates.” Playfulness in males signals that they are not aggressive and would not harm the mother and the offspring. So females would prefer playful and harmless males. And playfulness in females signals health and fecundity, according to Professor Chick. On this basis, adult playfulness seems to be attractive to the opposite sex.

Professor Chick and two of his colleagues investigated this hypothesis experimentally and supported that with data. The article is now published in the latest issue of American Journal of Play and is accessible for free here.
