You're talking about something completely different.
I'm telling you that there is an expected decrease in children and it's directly related to lockdowns and masks which has caused the children to become emotionally stunted.
What you're talking about is a general IQ statistic for a country.
You didn't specify the kids and kid IQ ratings are notorious for fluctuating. We'll see the true impacts in a decade. It's still early to draw conclusions.
Violence itself is a natural trait also. So it's one of those "violence may cause it but genetics cause the violence that causes it". Malnutrition is going to have a factor of course because then people genetics can't properly develop. I think a lot of the modern research on this though is not done fairly. Example: A country like Canada only really has black people because Canada immigrated in black people. Canada has standards for black people that immigrate in this Canada will only accept on average higher IQ blacks as part of its normal immigration process. To then compare Canadian blacks as well-nourished and then compare them to blacks back in their home country who are malnourished is going to give a highly biased result. Of course the Canadian blacks have higher IQ because they were filtered out specifically for their higher IQ as part of the immigration process.
If you take black people in the same country who are well-nourished vs. those who are not, you're again creating a bias because generally speaking the people with better genetics are going to end up getting more nourishment as a factor of their better genetics. Better genetics leading to them being more capable to get into position where they can get more resources and being born to families of superior genetics that have more resources etc...
To truly do an unbiased study, you need to essentially find a village that split into two randomly. The one village go good nourishment and the other village did not. Then compare IQs but that's not how a lot of the studies on nourishment are done. The way in which the studies are done, often lead to a lot of biases in them. However since nourishment advocates the "environment" angle, despite the flaws, it is pushed heavily by many in the field.
IQ hasn't dropped 20% because of masks. Average IQ in western countries had been dropping every year though because of immigration.

A fair enough criticism to be sure, but that still leaves violence and malnutrition which are more well documented.
