Others will straight up swear by the results and extrapolate all kinds of things from the data.

The results and interpretations of long-term studies of IQ among large populations is hotly contested. But there is the Flynn effect. Named after researcher James Flynn, this highlighted increases in IQ scores measured all across the world over time. On average, IQ scores were rising by about three points per decade starting in the first half of the 20th century.

And not by a little. Three points per decade might be one small step for a 10-year period, but over the course of half a century, that's one giant leap for mankind's intelligence.

And that explanation seems to be environment. If IQ was mostly genetic and fixed, you wouldn't expect entire populations to get smarter over just a few decades. Genes don't evolve that fast.

Absolutely. But other factors play in as well, like better health, cleaner water. And the one that kind of blew my mind was that we live in more cognitively demanding environments. People do more abstract thinking in the modern world. Modern life just requires more problem solving and, quote unquote, out of the box thinking.

Yeah. Family size is, in fact, one of the many factors experts point to to explain the Flynn effect. there are plenty of studies that suggest that IQ is going up or at least for several decades it was going up crap so are we getting dumber now There is some data pointing to a decrease in IQ in recent years. Norway, Denmark, Finland have all seen decreases in IQ ever since the 1990s.

In Britain, scores started dropping around the year 2004. In the United States, it's a mixed bag.
