This study seeks to compare two modes of categorising people: the machinic, in the form of Amazon's recommendation system, and the subjective in the form of social stereotypes in the fields of race, class and gender. The hypothesis under consideration asserts that there is a significant correlation between the subjective social categories that serve both to describe and to reproduce and perpetuate the structures of our societies and the categories constructed by collaborative filtering algorithms as they group online shoppers based on similar behaviour in an attempt to provide product recommendations that are of greater interest.

Methodologically, this study follows some of the patterns of Richard Rogers' Digital Methods. While regrettably, it was impossible not to import traditional sociological methods into the digital when considering human subjectivity and stereotypes, this study does endeavour to devise investigative methods that make use of computational logics afforded by natively digital objects. It combines a traditional survey – albeit with the digital twist of being carried out over Amazon Mechanical Turk – with browser automation and web scraping.

Research Method

This study comprises two investigations in two different domains. The first is an investigation into the categorisation of users implicit in the functioning of collaborative filtering algorithms likely employed in Amazon's recommendation system. The second takes the form of a survey of the subjective categorisation of people in the context of Amazon's categories of consumer goods. While the object of the second of these investigations is more closely allied to Digital Methods as it qualifies as natively digital, the second, though digitally mediated by means of Amazon Mechanical Turk (henceforth: AMT) surveys, is situated within the semiotics of human subjectivity and stereotypes.

The survey is composed of two AMT human intelligence tasks that asks respondents to match categories of consumer goods with social categories such as "male", "middle-class" or "black". The product categories are culled directly from and, although ultimately it is the former that is investigated in this study because AMT workers are predominantly American and Indian. (Ipeirotis) Both surveys have only 25 respondents and consequently cannot serve as more than a very crude approximation of American subjectivities.

The second part of the study involves web browser automation and scraping recommendations from This is largely done using the specially developed python package snu-snu and web application Unfortunately, the analytic capabilities of the software haven't been developed to a significant degree, with the consequence that the majority of analysis had to be carried out manually. It is clear that this placed considerable limitations on this study and as such the results are presented as preliminary.

The following sections elaborate on the decisions undertaken in arriving at which social categories and categories of consumer goods to investigate.

Product Category Selection

Although the Websites they sell many of the same products, the categories on and differ. At the very least, these differences give insights into the way in which Amazon's staff conceive of the dominant ideologies of the populations that the websites principally serve. For example, while includes a category in film and TV for "Gay, Lesbian & Transgender", merely includes one for "Gay & Lesbian". also lacks an explicit category for adult films.

Many of the categories on pertain to electronic equipment, sporting goods an mundane items for the kitchen or office. While no doubt many of the items in these categories have subtle associations with social categories and a few less so, there are categories of consumer goods that offer a greater array of social signification. Among these are clothing, music, books and films. It is worth noting that Items of clothing are somewhat problematic as gender and sex are hard-coded into the way they are categorised on

Chosen Category Set

Because of their rich interplay with social stereotypes and lack of contingency on biological sex, this study makes use of cultural genres as product categories. The two sets of categories selected are books and films. While music may have sufficed as well, and may be used in a future study, two root categories are judged sufficient at this point.

Social Category Selection

Part of this study requires survey respondents on Amazon Mechanical Turk to match categories of books and films derived from to broad social categories under the headings of race, gender and class. Below are summaries of the reasoning behind the treatment of each set of categories.

Social Class

There are many models of social class in the UK to choose from. The seven categories employed by the Great British class survey of 2013 – devised using measures of social, cultural and economic capital (Savage et al. ) – serve as a comprehensive approximation of how contemporary British society is stratified. The National Statistics Socio-economic Classification and even the NRS social grade of the 1970s provide reasonable granularity along occupational lines. However, such models are poorly suited to this study for two reasons: first, an estimated 80% of Amazon Mechanical Turk users are American and Indian (Ipeirotis), models constructed with reference to British society may not apply, and second, however accurate the models, their category names are unlikely to be common knowledge outside of marketing and the social sciences.

This study settles on the tetrad of working class, upper class, lower class and middle class. While this is an approximation based on general ideas gleaned from an English milieu, deploying complex taxonomies of American class such as the model developed by Gilbert Dennis in The American Class Structure would lead to some of the same problems in communication with respondents as those from England. The result is a somewhat vague compromise that will not sit entirely uncomfortably in an Anglo-American context.


The survey is concerned with social stereotypes, and thus distinguishes the social categories of gender from the biological categories of sex. As outlined below, this distinction is far from unproblematic.

This study resists the temptation of following Crany-Fancis, and conceiving of gender as 'the culturally variable elaboration of sex[.]' (4) The pitfall of positing biological sex as the stable foundation upon which various genders are constructed is avoided. Instead of figuring sex as extra-discursive: both in that is is cordoned off from the humanities and social sciences and that it can be viewed independent of human purposes (Harrison and Hood-Williams), this study acknowledges the discursive forces at play in the construction of sex, reified by medicine in the surgical assignment of binary sex to the estimated 1% of newborns' bodies that differ from standard male or female physiology. (Blackless et al. Qtd. in Eckert and McConnell-Ginet 11) However, as it is concerned with social steriotypes, it seeks to avoid such grey areas.

Instead, this study draws on the ideas of R W Connel, who posits masculinities, as groupings of interrelated social practices, forming hierarchies and intersecting with other clusterings of social categories. While masculinities and femininities more accurately reflect the plurality of social practices subsumed under gender, to aid clarity, the terms masculinity and femininity are used.


As this survey pertains to, the racial categories are those of greatest relevance to the USA. These are based on the most populous groups according to the official American census, including – following Humes et al. – the ethnic category Hispanic.


As social categories intersect, complexities emerge, as in the case of the particular relationship working-class women have to care in both domestic and occupational settings. (Armstrong) As survey respondents can select multiple identity categories, they may perceive themselves as specifying intersectional identities: white working class masculinities may be mapped to "humour & entertainment" books, for example. In the case of sexualities, a decision as to the use of "gay" and "lesbian" or simply "homosexual" would need to be made. The latter encourages a reading of homosexual femininities or masculinities in to a user's selection of "homosexual" in combination with a gender category. Exhaustive permutations of combined social categories such as masculine-heterosexual-white-middle-class risk overcomplicating the survey and verge on the absurd.

A consequence of ignoring intersectionality is that the sets of genres derived from each category are monolithic and therefore limited in their applications. Combining the monolithic categories in order to derive some sort of approximation of intersectional identities amounts to little more than an exercise in curiosity. On balance and in the interests of simplicity, neither of the surveys make reference to explicitly intersectional identities.

Technical Considerations

In order to deploy its research, this study requires a piece of browser-automation based code that is capable of searching within the hundreds of product-sub-categories on Amazon. Due to inconsistencies in the structure of the pages for the main categories, it isn't practical to develop something that can scrape these categories and make them available for selection. The first attempt at a solution involved manually storing the URLs of sub-categories and navigating to them. This failed as automatically logged users out when the browser attempted to access these pages directly. Perhaps they detected a behaviour associated with web scraping.

After this setback, the only option was to search within the root categories of Book and Film & TV, entering the name of each sub-category as a search term. There is little doubt that this harmed the precision of the study and may have skewed the results.

Preliminary Findings

This section outlines and conducts an analysis of both the results of the two traditional surveys and those based on the scraping and analysis of Amazon recommendations. As indicated by the title, not even tentative conclusions are drawn from these findings as the samples sizes and breadth and depth of analysis were greatly restricted by a lack of resources both pecuniary and temporal.

Book and Film Genre Surveys

Respondents were given book and film genres and asked to match them to social categories, the members of which were likely to buy, read or watch items within those genres.


The results pertaining to social class were mostly explicable in terms of cultural capital and education. Those genres that indicate higher levels of cultural capital and leisure time such as Travel and Arts & Photography in books and Performing Arts and Documentary in film and television are most commonly selected by respondents for a stereotypical member of the upper class. Those indicative of technical skills and some cultural capital, such as Literature & Fiction and Computers & Technology, along with genre fiction among books and the more popular genres of Horror and Comedy from film and TV are associated with the middle-class. Those genres selected for the lower and working classes are exclusively related to popular entertainment, religion and quotidian life.


Interpretation is limited here due to a lack of detailed understanding of race in America. Viewed through the same lens as were the categories of class: the white and asian categories have a higher proportion of genres associated with affluence, education and high culture, than those of black and Hispanic.


Many of the genres here starkly echo the dichotomies of poplar essentialist thought, we find such oppositions as women are weak, men strong – women irrational, men rational; women cooperative – men competitive – woman passive, men active – women timid, men aggressive – women emotional, men impassive. (Eckert and McConnell-Ginet 35) By way of books, femininity is assigned Romance, Craft, Hobbies and Home and Children and Family; films and TV yield a similar selection comprising Drama, Soap Opera and Performing Arts. The stereotypes that inform sex role theory, which assigns a broadly expressive role to females and an instrumental role to men (Connel 22) are somewhat evident in the assignment of Engineering and Transport, Science and Maths and Business and Finance books to masculinities, as well as action films and sports shows.

Digital Investigation of Amazon


Due to time constraints, and due to this study already having given a greater degree of consideration to gender, only the masculine and feminine categories have been analysed.

Although only 200 items were added to the shopping list and wish-list of each account used, the number of recommendations given by Amazon exceeds this number. As all recommendations were for books, and 100 TV and film items were added to the shopping list before any books were added, it seems certain that there are at least twice as many recommendations as list-adds. However, as many videos were streaming items and instead added to watch-lists, the extent of the recommendations is not entirely clear.

Of those recommendations that were scraped, a significant proportion of them fall into the categories that were explicitly searched for, viewed and added to lists (see appendices 3.1.1 and 3.2.1). The is markedly the case for the feminine category where 90% of recommendations fall under either the chosen or reserved genres. What could hesitantly be described as gender disparity seems evident here as only 56.3% of recommendations for the masculine category fall under the used or reserved genres.

The Status of the Hypothesis

Although the number of recommendations scraped is too low to base any firm conclusion on, these preliminary results do not support the hypothesis. For the masculine category, only 5.6% of recommendations fell under the reserved genres. Despite most of the genres of the recommended products for the feminine category falling under the selected genres, only 0.5% fall under the reserved. These results appear to refute the hypothesis as stated.

All that is refuted is that the particular set of stereotypes gleaned from a small number of surveys match a subset of the recommendations generated by Nevertheless, the hypothesis is certainly no stronger than it was when untested.


The postulate that there is some correlation between social stereotypes and the profiles used by to generate recommendations – if such categories are indeed used – is in no way supported by the approximations of stereotypes constructed in this study or the recommendations analysed. Though there are a peppering of suggestive anomalies, it seems likely that subjective social categories, at least those on the molar scale of class, gender and race, do not significantly structure's recommendation system. Product-to-product similarities seem to play just as significant a role, if not more so.

Due to the small sample sizes, these results do not put an end to the question of how recommendation systems categorise people. It may be worthwhile to carry out further analysis on a greater number of recommendations or to develop a hypothesis that is aimed a social categories rather more molecular than the molar categories addressed in this study. Such a set of categories could be provided by the Great British Class Survey.
