Where did you get that chart from? When I look at Wiki (I know, not perfect data by any stretch), most of the nations you listed are close, except for Israel. They show up as a 94 IQ and are ranked 59th. I also couldn’t find Iceland on the Wiki either. Here is the link I was looking at:

It was Bing, one of the first results for “IQ bell curve” that had a cut-and-paste link.
Here’s wiki on Ashkenazi Jews.

I have a store with a washer down. Will be back shortly.
I think I figured out the issue with your chart. It appears to include the West Bank/Gaza in “Israel” which would bring the average down.
