I guess it depends on who you ask and what locality. But it was measured by
1999 in Denmark.
If pollution levels are falling- dioxins among other things at least have been- I wouldn't blame pollution for this reversal. Lifestyle changes might be a factor considering things like the effect of the American diet on development (not just obesity). Another explanation is the weak but measured negative correlation between IQ and number of children.
This guy thinks genotypic IQ will fall by .8 every generation. It's interesting to consider if IQ reaches equilibrium over time and genotypic intelligence will fall back to the same point every time it finishes going up. People will be just as dumb in 2900 as they were in 1900 if evolution takes it's course.
It's not an either-or situation. Detain insurgents if you want, but detain them as you would detain, you know, a human being charged with a crime. I don't disagree with holding people that are dangerous, but Gitmo was such a horrible thing.
It's not just that; the abuse scandals created a lot of unrest when they were found out. But what we were talking about in the previous thread (before it got locked) was mainly whether terror suspects should be put on trial.
