While a variety of writers have suggested these characteristics strengthen socially constructed ideas about beauty, research from evolutionary psychology suggest a different view. Gad Saad is the pioneer in the study of evolution in consumption. It is the study that applies evolutionary psychology theories to study consumer behavior. He has proposed an etymological system of evidence that examines the arguments for an evolving male sexual preference for females who have an hourglass-shaped body.
They consider a wide range of evidence from various disciplines which appear to reach an unambiguous conclusion. In the context of a preference for an hourglass figure in males and females, Saad presented evidence that the hourglass figure carries biological signs that indicate fertility and youth, which results in a sexual preference that is cross-cultural between men based on a variety of psychophysiological results. In the domain of sexual services it is common to see an hourglass figure (operationalized as the waist-to-hip ratio is approximately 0.70) is regularly mentioned by female sex workers in their online ads for their services in the form of a figure similar to this ratio linked to a higher price that female escorts charge. Particularly with regard to teen sex doll, adult-sized models are reported as having an average ratio waist to hip of 0.68 . According to these numbers and the notion that cheap sex dolls promote the socially constructed ideals of beauty is questioned by the opposing belief that dolls are simply reflecting an evolving preference of males for a specific physique and are therefore determined by the market demand.
In short, the preference of customers determines the design of models, more than in reverse. But, longitudinal studies examining the impact of exposure to mini sex doll and their effects on indicators of objectification and preference for body types could be an excellent base for examining the the validity of these different theories.
As has been mentioned previously that there isn't any research that specifically examines the causal relationship between sex doll and the propensity for sexual violence. However, the literature indicates these links are likely to be rooted in philosophical or ethical views [9, 20-22 28 51[9, 20-22, 28, 51]. In the absence of this causal proof certain philosophical arguments have gone as that they have considered whether robots' sexual relations is a form of rape in and of itself . In one instance, a conceptual piece written by Elen Carvalho Nasciemento declared the following "sex robots exploit female form - eventually becoming male, and maybe even children - to gain a unilateral physical pleasure. The purchaser of the item which is a sex machine that is humanized is able to perform whatever they wish and without consent". Sinziana Gutiu went on to say that she is asserting that the programming capability of sex robots enables their owners to engage in rape.
