divorce rates among upper income, educated folks is low. . . closer to 10-20% range. . . and to be fair some matches are just plain bad or green card marriages.
My point was that, no matter how you fudge the numbers, it's impossible to chalk up bad divorces as outliers. Outliers are defined as 3 standard deviations from the mean in a normal distribution, so the parent was implying that bad divorces occur at a rate of 0.1% or less--which is off by at least one order of magnitude.
