In November, the European TV channel Arte aired an hourlong documentary, Demain, tous crétins?—Tomorrow, everyone’s an idiot?—on a topic that would seem to be of great importance. It starts with a London-based researcher, Edward Dutton, who has documented decades-long declines in average IQs across several Western countries, including France and Germany. “We are becoming stupider,” announces Dutton at the program’s start. “This is happening. It’s not going to go away, and we have to try to think about what we’re going to do about it.”
[...] It’s wrong to hint that scores on tests of memory and abstract thinking have been falling everywhere, and in a simple way. But at least in certain countries—notably in Northern Europe—the IQ drops seem very real. Using data from Finland, for example, where men are almost always drafted into military service, whereupon they’re tested for intelligence, Dutton showed that scores began to slide in 1997, a trend that has continued ever since. Similar trends have been documented using data from Denmark, Norway, and Sweden. At some point in the mid-1990s, IQ scores in these countries tipped into decay, losing roughly one-fifth to one-quarter of a point per year. While there isn’t any sign of this effect on U.S. test results (a fact that surely bears on our indifference to the topic), researchers have found hints of something similar in Australia, France, Germany and the Netherlands.
Are we becoming dumber, as in losing cognitive function, or merely less-well read?

Everyone knows it coincides with removing lead from petrol (or was it removing lead from Alcohol? I forget)

Petrol. Sadly, but an enlightening study is of the lead industry in the 1800s-1900s industrial revolution. The lead industry employed chemists to find ways to add lead to everything, and then sell the public, or at least the buyers in the distributors. (WalMart's corporate buyers shape much of the world's consumer products that are available...)
So they put lead in paint, which we're still paying for- it's very difficult and costly to remove lead-based paint, which was used up until the late 1970s. They also put it in petrol- it raised octane a bit, and lubricated engine valves. It was fairly easy to make valves and valve seats harder, and use better valve guides to eliminate the need for lead.

It's OK as long as you don't lick it
