The problem this data will have is it’ll just be two extreme points of view. Some people regret heavily, some heavily glad. Anyone in between probably not represented because they can’t be bothered to express an opinion.

I saw a sign recently that just read “success is very similar to failure” and I absolutely agree.

The difference in your life and happiness between getting what you want and not is often much smaller than you expect.

Considering the real value is in the comments, I think that's fine.

Also this reasoning applies just as much to any sort of review feature elsewhere. Yelp, Amazon, Glassdoor, IMDB, etc. Most people who bother to leave a review are those that have strong opinions one way or the other.

It loses a lot of data in nuance, as well. I regret never having an SO halfway through my life. But it's easy to gloss over the fact that not all relationships are helpful and can lead to grief and consequences that exceed the cost of being single. So what I'm really saying is that I regret forgoing a very specific case of having an SO.
