Mm, that doesn't look terribly convincing compared to a real study like this one from Stanford which shows a much lower figure: (link in the article to the full study if you can access it) https://www.washingtonpost.com/news/wonk/wp/2016/03/08/how-m...
Thanks, I was doing a quick search but you found a better looking one, I agree.
Nevertheless, even this shows that the work place is a significant factor to meet a partner - even if it has lost relevancy. Which leads to the question why. Is it because the other places somehow got more effective for that purpose, or is it fear of being perceived as crossing boundaries which makes people hesitant to try. Both (or other) explanations seem imaginable to me.
