Like someone else said above, communities with shorter dating cycles (i.e. 3 or 4 dates before engagement) tend to have lower divorce rates. Communities where they date for 6 months and even longer, tend to have higher divorce rates than even the communities that are mid-range (i.e. 9-10 dates before engagement.)
So if there is an argument to be made, it is surely that shorter dating tends to work out better.
