Sally and Tom live in the same street and are both looking for love. Both Sally and Tom have average looking faces. Sally is a 37 year old overweight unemployed divorced stay-at-home mother of a 12 year old boy. Tom is a fit single, childless, 32 year old with a stable job as a civil planner, enjoys the outdoors and is a runner. Sally and Tom join Tinder at the same time. Both add a single photo of themselves and list their hobbies and family circumstances. Both Sally and Tom decide to swipe right(like) every photo they see on their screens.
After both have done this for a thousand photos they only return to the app a week later. Sally has 200 mutual likes and message from men of various ages wanting to hook up. Tom has no mutual likes.
As a result Sally has a high expectation of her desirability and Tom forms a very low expectation of his desirability.
One could argue people are biased for Sally/ biased against Tom but in a real life scenario if Sally and Tom went independently to a club, Tom would get more interest shown in him than Sally. So the word(s) I'm looking for is related to a specific scenario/use case i.e. Tinder but not in general.
If I look at words like bias, prejudice, discrimination ,inequity, favouritism it has the feeling of
unfair which is not want I want to convey, but I rather want to say an illogical advantage not applicable to real life, just Tinder.
Since online dating sites like Tinder did not exist 20+ years ago the word I though of is
Definition: noun the defining spirit or mood of a particular period of history as shown by the ideas and beliefs of the time.
However what I am thinking of isn't related to a specific period but rather a situation e.g. realm of Tinder.
Other similar words in vogue, feeling, atmosphere just don't fit in what I am trying to say
How do I explain this either with word(s) e.g. zeitgeist or alternatively with something to describe the postive/negative bias on each person?
