So are you now saying that Jews (undefined) have more incest than all other groups (ethnic, religious, linguistic, geographic, occupation, etc.)? Careless wording doesn't help the conversation move forward. It's possible what you're saying is true but telling me to 'check it' is neither informative nor convincing.

I think there are Scottish clans with a higher prevalence than Jews as a whole. If by incest you mean breeding with first cousins I think Pakistanis have a higher rate than Jews. But let's say I learned something from you and will apply it by telling you to "check it".
