Judith Duportail and “The Algorithm of Love”

The story begins with the prestigious French journalist as the protagonist. At 28, Judith broke up with her partner and after the breakup, she started a new direction: she went back to the gym and yes, she turned to Tinder again. And likewise it is explained on the back cover of his latest book ««:

«After a first moment of euphoria and ego boost when the matches ―or flirts, in Tinder parlance― happen one after another, Judith discovers something unexpected that shocks her and feeds her curiosity in equal parts: the app has and saves hidden in its server a “note of desirability” of each user. The impossibility of accessing this note will make you undertake an investigation in order to discover how the application really works, what private and sensitive information each user has and what use he makes of it, and at the same time also find out how desirable it is itself. ».

Indeed, one day he came across an article published by the Fast Company portal entitled «I regret discovering my secret desirability score on Tinder» in which a journalist told how, by chance talking to Sean Rad, the founder and CEO of Tindercame to know that in the app everyone has an “ELO”, a number that rates their desirability. This indicator is not a simple indicator of beauty or something punctual, but rather it is a complex system to evaluate the desirability of a profile considering a great variety of factors.

800 pages of your secrets

Judith, after reading that, decided to investigate more about this topic so he wrote to the company to request information about the platform’s algorithm to understand what information they had about it and how they used it. It was easy? No, so, after several unanswered requests, she decided to officially present herself as a journalist and to do so together with Paul-Olivier Dehaye, a well-known privacy activist, and Ravi Naik, a human rights lawyer.

This is how it worked and she received a total of 800 pages with all the data that Tinder had collected about her (including lots of matches and conversations) since the famous application had been downloaded in 2013.

«I received about 800 pages with information such as my likes on Facebook, my Instagram photos, my studies or the age range of men I was interested in.Judith explained.

Because besides, The information is obviously complemented by everything they collect from us on the Tinder platform itself..

They analyze, for example, how many times we connect, what kind of people are interested in us, what words we use or even how long people spend on our photo before seeing the next candidate.

This level is awarded to each individual based on their history of results and is used in tournament rankings such as FIFA. FIFA? But what does it have to do with anything? Let’s investigate a little more.

The ELO ranking

ELO, that mysterious “desirability score”, subtracts points if a popular user on Tinder rejects you or if a person with a “poorly positioned” profile matches you.

Through this identification and subsequent analysis of the data obtained, Tinder can estimate aspects such as the IQ of users or their general emotional state.

In addition, linked to what was previously mentioned about the information that Tinder collects, to analyze these aspects, it also considers things such as the average number of words we use per sentence or how many words with more than three syllables we write. «People with the same level of attractiveness are more likely to understand each other»they acknowledge in their patent.

Tinder chooses for you (and for all your partners)

And if you are interested in finding out more about this topic, the book «The algorithm of love» de Duportail explains all these investigations in detail and concludes with an interview with Sean Rad, from Tinder.
