Is there any evidence of those cohabiting prior to marriage being more likely to divorce? In my circle, the happy marriages are all those of us who lived together for a while first. The divorced / unhappy marriages some did, some didn't. I would think it'd more likely be the other way round, as if you live together first you already know if you actually can stand to do it long long long term.
I'm also slightly suspicious of the idea that cohabitation prior to marriage means you are more likely to lead to divorce. Where has this come from?
If this is true, and it may be true as I've heard it before, I would guess it's more reflective of attitudes to marriage and divorce than something inherent about cohabitation. It probably includes a lot of older couples for whom cohabitation pre marriage wasn't an option.
I am in my early 50s and I know literally no one who married and had kids without having cohabited first. And honestly I would strongly advise my daughter (should she want to marry) not to do so without having lived with her partner first. It seems absolutely nuts to me that you would make a theoretically lifetime commitment to live with someone and raise children with them without testing out whether you could live with them first. Being able to cohabit well is probably even more important than sexual compatibility and personality/values etc.

Marriages between devoutly religious people (who are more likely to try and abstain before marriage) also have better outcomes.
That's probably true but it's a not a good thing as a rule. A couple in a devout religious community will face a huge amount of pressure to remain married and their personal feelings about one another are largely irrelevant. It doesn't tell you anything about the happiness of the marriage.
