Thanks for the reply. You mention reliability of stats. The best, most reliable research is always to be found published in professional journals (not popular mags) and University research.
The second link in your post is to an "as yet unpublished study," not a good source. Your first link, however, to the University of Chicago research, is legit. Interesting!!! However, the study is over a decade old. Many professional journls of psychology have published research on infidelity since then... that's important, because to my knowledge, infidelity is a problem that has been on the RISE for quite some time, thanks mostly to the internet and to people spending longer hours in the workplace setting.
I WISH I remembered the source of my "80% of all marriages" statistic. The reason I do not have the source, is because the statistic was quoted to me just last semester, by a marriage and family sociologist I was taking a class from at the University in my city. I will try to e-mail him for his source.
I think it's pretty obvious that there's a whole lotta hanky panky going on out there, but even it were some not-so-big problem in society (which I doubt!), it would still be deserving of understanding it, rather than judging it. It's really hard to understand a complex life-event like infidelity, or the people involved, when one is busy moralizing, that was my only point.
