Interrelationship between Share of Women in Parliament and Gender and Development: A Critical Analysis

Gender and development are among the two most important components of any economy to sustain its perpetual and sustainable economic growth in both the long as well as short run. The role of women in parliament and the interrelationship between gender and development is critically analysed. Women’s representation in parliament is the dependent variable and the predictor variables considered are gender development index, female access to assets, female labour force, and country GDP per capita. Data were collected from the UNDP human development report for the period 2015 to 2021–2022 and World Bank for 188 countries of which finally 159 were considered to develop the model based on data availability. We have used the theoretical lens of social stratification theory and gender role theory to frame the hypothesis. A random effects model-based panel regression analysis of the data indicated a strong positive relationship between gender development index and the dependent variable, but no relationship between female labour force, and access to assets. The study addresses a critical gap in policy and development of the literature on gender, politics, and development using a global data set, establishing the importance of indicators such as gender development index, and laying down the path for future research on the subject.

Mismatch between scientific theories and statistical models

Yarkoni recommends that psychology researchers should take care to align their statistical models to the verbal theories they are studying and testing. This principle applies not just to qualitative theories in psychology but also to more quantitative sciences: there, too, mismatch between open-ended theories and specific statistical models have led to confusion.

Seven steps toward more transparency in statistical practice

We argue that statistical practice in the social and behavioural sciences benefits from transparency, a fair acknowledgement of uncertainty and openness to alternative interpretations. Here, to promote such a practice, we recommend seven concrete statistical procedures: (1) visualizing data; (2) quantifying inferential uncertainty; (3) assessing data preprocessing choices; (4) reporting multiple models; (5) involving multiple analysts; (6) interpreting results modestly; and (7) sharing data and code. We discuss their benefits and limitations, and provide guidelines for adoption. Each of the seven procedures finds inspiration in Merton's ethos of science as reflected in the norms of communalism, universalism, disinterestedness and organized scepticism. We believe that these ethical considerations-as well as their statistical consequences-establish common ground among data analysts, despite continuing disagreements about the foundations of statistical inference.

Evolution, the Menstrual Cycle, and Theoretical Overreach

A considerable amount of recent psychological research has attributed a variety of menstrual-cycle-related changes in social behavior to evolutionarily adaptive functions. Although these studies often draw interesting and unusual conclusions about female emotion and behavior within evolutionary theory, their significant limitations have not yet been addressed. In this article, we outline several methodological and conceptual issues related to the menstrual cycle that constitute threats to the internal validity and theoretical integrity of these studies. We recommend specific guidelines to address these issues and emphasize the need to apply more comprehensive and sophisticated theoretical structures when considering menstrual-cycle-related changes in emotion and behavior.

Defending the Queen’s Pride: Effect of the menstrual cycle phase on conspicuous consumption

Women experience both physical and psychological changes during different phases of the menstrual cycle (MC), which can affect their decision making. The present study aims to investigate the impact of the MC on women’s preferences for conspicuous consumption. In three studies, women in the low-fertility phase were found to be more inclined toward conspicuous consumption, with the MC effect on conspicuous consumption being mediated by the extent of pride. We assumed that women in the low-fertility phase would feel less proud due to an evolutionary drive and that they would consume conspicuous products as a means of compensation. Meanwhile, women who were only children did not manifest such behavior. We infer that women from one-child families may have a greater sense of security and confidence, which buffers the mediating effect. This research contributes to both evolutionary psychology and marketing research and provides new insights for future studies.

The Stability of Individual Well-Being in Short Windows of Time: Women's Perceptions across the Ovulatory Cycle

Empirical research on well-being has rapidly increased in recent years. One of the most dominant issue concerns the degree of cross-situational consistency and stability of well-being across time, and this is of particular relevance to women life. The aim of this study was to verify the stability of women well-being in short windows of time, specifically across menstrual cycle phases. A within-subject design with 25 normally cycling women (range: 19-26 years) was carried out. The multidimensional assessment of well-being included the administration of psychological well-being, self-esteem, and emotional self-efficacy beliefs questionnaires during both high and low-fertility phases. The results showed the stability of the level of individual well-being across menstrual cycle phases. Albeit preliminary, results indicated that women representations of their well-being do not change according to menstrual cycle. Rather, an effective organization and integration of the entire self-system appears sustained by the stability of well-being measured through a multi-componential assessment over short periods of time.

Increasing Transparency Through a Multiverse Analysis

Empirical research inevitably includes constructing a data set by processing raw data into a form ready for statistical analysis. Data processing often involves choices among several reasonable options for excluding, transforming, and coding data. We suggest that instead of performing only one analysis, researchers could perform a multiverse analysis, which involves performing all analyses across the whole set of alternatively processed data sets corresponding to a large set of reasonable scenarios. Using an example focusing on the effect of fertility on religiosity and political attitudes, we show that analyzing a single data set can be misleading and propose a multiverse analysis as an alternative practice. A multiverse analysis offers an idea of how much the conclusions change because of arbitrary choices in data construction and gives pointers as to which choices are most consequential in the fragility of the result.

Automatic female dehumanization across the menstrual cycle

In this study, we investigate whether hormonal shifts during the menstrual cycle contribute to the dehumanization of other women and men. Female participants with different levels of likelihood of conception (LoC) completed a semantic priming paradigm in a lexical decision task. When the word 'woman' was the prime, animal words were more accessible in high versus low LoC whereas human words were more inhibited in the high versus low LoC. When the word 'man' was used as the prime, no difference was found in terms of accessibility between high and low LoC for either animal or human words. These results show that the female dehumanization is automatically elicited by menstrual cycle-related processes and likely associated with an enhanced activation of mate-attraction goals.

A Psychophysiological Mechanism Underlying Women’s Weight-Management Goals

Three studies demonstrated that conception risk was associated with increased motivations to manage weight. Consistent with the rationale that this association is due to ovulatory processes, Studies 2 and 3 demonstrated that it was moderated by hormonal contraceptive (HC) use. Consistent with the rationale that this interactive effect should emerge when modern appearance-related concerns regarding weight are salient, Study 3 used a 14-day diary to demonstrate that the interactive effects of conception risk and HC use on daily motivations to restrict eating were further moderated by daily motivations to manage body attractiveness. Finally, providing evidence that this interactive effect has implications for real behavior, daily fluctuations in the desire to restrict eating predicted daily changes in women’s self-reported eating behavior. These findings may help reconcile prior inconsistencies regarding the implications of ovulatory processes by illustrating that such implications can depend on the salience of broader social norms.

Menstrual cycle phase does not predict political conservatism

Recent authors have reported a relationship between women's fertility status, as indexed by menstrual cycle phase, and conservatism in moral, social and political values. We conducted a survey to test for the existence of a relationship between menstrual cycle day and conservatism. 2213 women reporting regular menstrual cycles provided data about their political views. Of these women, 2208 provided information about their cycle date, 1260 provided additional evidence of reliability in self-reported cycle date, and of these, 750 also indicated an absence of hormonal disruptors such as recent hormonal contraception use, breastfeeding or pregnancy. Cycle day was used to estimate day-specific fertility rate (probability of conception); political conservatism was measured via direct self-report and via responses to the "Moral Foundations" questionnaire. We also recorded relationship status, which has been reported to interact with menstrual cycle phase in determining political preferences. We found no evidence of a relationship between estimated cyclical fertility changes and conservatism, and no evidence of an interaction between relationship status and cyclical fertility in determining political attitudes. Our findings were robust to multiple inclusion/exclusion criteria and to different methods of estimating fertility and measuring conservatism. In summary, the relationship between cycle-linked reproductive parameters and conservatism may be weaker or less reliable than previously thought.

Beyond Power Calculations

Statistical power analysis provides the conventional approach to assess error rates when designing a research study. However, power analysis is flawed in that a narrow emphasis on statistical significance is placed as the primary focus of study design. In noisy, small-sample settings, statistically significant results can often be misleading. To help researchers address this problem in the context of their own studies, we recommend design calculations in which (a) the probability of an estimate being in the wrong direction ( Type S [ sign] error) and (b) the factor by which the magnitude of an effect might be overestimated ( Type M [ magnitude] error or exaggeration ratio) are estimated. We illustrate with examples from recent published research and discuss the largest challenge in a design calculation: coming up with reasonable estimates of plausible effect sizes based on external information.

Evolutionary Awareness

In this article, we advance the concept of “evolutionary awareness,” a metacognitive framework that examines human thought and emotion from a naturalistic, evolutionary perspective. We begin by discussing the evolution and current functioning of the moral foundations on which our framework rests. Next, we discuss the possible applications of such an evolutionarily-informed ethical framework to several domains of human behavior, namely: sexual maturation, mate attraction, intrasexual competition, culture, and the separation between various academic disciplines. Finally, we discuss ways in which an evolutionary awareness can inform our cross-generational activities—which we refer to as “intergenerational extended phenotypes”—by helping us to construct a better future for ourselves, for other sentient beings, and for our environment.

Why isn't everyone an evolutionary psychologist?

Despite a widespread acceptance that the brain that underpins human psychology is the result of biological evolution, very few psychologists in any way incorporate an evolutionary perspective in their research or practice. There have been many attempts to convince mainstream psychology of the importance of such a perspective, mostly from those who identify with "Evolutionary Psychology," and there has certainly been progress in that direction, but the core of psychology remains essentially unevolutionary. Here I explore a number of potential reasons for mainstream psychology continuing to ignore or resist an evolutionary approach, and suggest some ways in which those of us interested in seeing an increase in the proportion of psychologists adopting an evolutionary perspective might need to modify our tactics to increase our chances of success.

Is preference for ovulatory female's faces associated with men's testosterone levels?

Women's ovulation is perceivable with different senses. Already subtle face shape differences are enough to trigger men's preference for the ovulatory female. The aim of the present study is to investigate if men's testosterone level can be linked to their preference for the ovulatory female. Thirty-nine heterosexual participants were shown face pairs of which one of them was transformed to the shape of a prototype face of a woman in her luteal cycle phase and the other was transformed to the shape of a prototype face of an ovulatory woman. Participants were asked to choose the face which they perceived as being more attractive (attractiveness task), or the woman with whom they would have better chances to get a date (dating task). In both tasks, the ovulatory female was chosen more often. Testosterone was not predictive for the chosen face; regardless of testosterone level men preferred the ovulatory woman. However testosterone predicted how confident the men were with their choice. Men with lower testosterone levels were more confident with their choice than men with higher testosterone levels.

Beyond the negative: political attitudes and ideologies strategically manage opportunities, too

Hibbing et al. use evolutionarily derived logic to suggest that political attitudes are related to responses to negative features of the environment. We suggest that the authors focus too narrowly on the negative and contend, instead, that a more comprehensive evolutionary approach focusing on people's responses to threats and opportunities will better account for variation in political attitudes.
