After taking the survey, I must express two things that I've realized during the survey.
For one, my personal preference may not be the chest that is "more aesthetically pleasing" even though that is what the survey explicitly asks for. There are considerations other than aesthetics that should be considered. In my opinion, instead of the survey showing two cases (one perfect, one slightly afflicted), the survey should show just the afflicted chest and ask "is this aesthetically pleasing or not". Of course the perfect chest is more pleasing, but that does not mean that there was any problem requiring intervention on the other chest.
I've noticed that asymmetry with regards to breast size really are not a problem (for me), even in extreme cases. I've noticed this asymmetry in many women who have not had breast cancer or other afflictions. However, nipple asymmetry does stand out, especially vertical asymmetry. Two nipples at different heights does look terrible, and if aesthetics are an issue then I could understand performing surgery for those cases.
I do understand your concern - however the data collection works a little bit different "under the surface" as it seems.
In the statistical analysis of the data we do not look at the "complete" breast images.
The study is designed in a way, that the most important parameters around breast (reconstruction) surgery (e.g. breast size, breast shape, areola size, areola position, scars etc.) are being combined in 88 images in a way that in the end allows us to extract the data "broken down" to the different parameters. So the result of the study will not be "people like image X more than image Y".
Instead we want to get a far more profound understanding of the influence the different parameters have on the perception of the breast. As we also measure the decision time, results of the study will be something like: "most people (or maybe just men - that's what we want to find out) tend to accept breast size asymmetry more then areola asymmetry. The decision happens much faster on areola asymmetries - so that seems to be more obvious and therefore has to be taken more care of during the surgery."
Nobody has every done a profound analysis of these individual parameters alone - so that is where we see huge potential for a better understanding.
I hope that explanation helps a little bit! Thank you very much again for your support!
From very much experience in designing and running online interactions, including polls, I can tell you with authority that you cannot trust the decision time of answers online. You don't know that they user didn't look at a quick text message on his phone, or adjust the music volume, or go to the bathroom, or take a call, or had a network issue, or your images didn't load quickly, or the dog didn't bark suspiciously, or a loud C-130 just flew overhead, or any other of a million things. I highly suggest disregarding that feature.
