Midwives have been told about the benefits of “close relative marriage” in training documents that minimise the risks to couples’ children.
The documents claim “85 to 90 per cent of cousin couples do not have affected children” and warn staff that “close relative marriage is often stigmatised in England”, adding claims that “the associated genetic risks have been exaggerated”.


Am I the only one that thinks 15% is way too high of a chance to be rolling the dice like that? I’ve played enough XCOM to know that even a 99% success rate will still bite you in the ass.
Yeah, but what can the NHS do with that?
They just treat folk. People will make those choices regardless.
Now tell them vaccinees have less than 15% chance of causing autism.
While it’s true that the chance is less than 15% you missed about 10^-5 0’s there.
That’s because like NHS in this case, X-COM *lies *.
It lies in your favor, though. On difficulties below the highest, the modern games have hidden modifiers that affect the hit chance that you can’t see, but all of them are cheating for you. IIRC your hit chance secretly increases when you have missed shots recently, when you have dead soldiers, when you are outnumbered, and maybe some other things.
