Reddit and internet forums have a bias for negative anecdotes.

Do you have any proof or even just actual argument whatsoever that the very specific thread I linked to has any such alleged problems? Did you actually even bother to read the many comments there? Unlike your single-phrase blanket statement they are actually quite thoughtful. You could learn a thing or to on Internet discussions from that thread.

There was no prediction or conclusion made whatsoever, it was a number of for the Internet quite high quality personal observations. If you are unable or unwilling to accept the personal observations of those people, here doctors, then the issue is on your side.

We also know that there indeed is a significant difference in culture, we can see that in elections and elsewhere. That too is a "known bias", which you also ignore.

For example:

https://www.sciencedirect.com/science/article/abs/pii/S07430...

https://en.wikipedia.org/wiki/Urban%E2%80%93rural_political_...

So differences in general are real, and you cannot simply dismiss any anecdotes as "bias", especially since there never was a claim for that thread to be anything more than that.

This divide is also not the same all over the globe, the US may be more extreme (example: https://www.uva.nl/shared-content/uva/en/news/news/2024/03/t... -- "Compared to the US, UK and Canada, overall levels of urban-rural electoral divides are still substantially lower in most European countries, due to centrist parties attracting support from both urban and rural areas."). That too has some interesting comments showing this in that thread, with the bad anecdotes coming mostly from US doctors.
