In the 1990s, Switzerland transitioned from a migration policy that only let in low-skilled labor that wouldn't compete with locals to one where migrants weren't restricted to being low-skill.

Accordingly, on the tail-end of the low-skill era in the year 2000, 1st-generation migrants' kids performed poorly on the PISA. You can see that poor performance very clearly:
After the immigration reform, high-skilled immigrants started seeking entry to Switzerland, and they did manage to get in. As a result, by the next PISA administration, the gap between 1st- and 2nd-generation immigrants was greatly diminished:
In a 2015 paper, Cattaneo & Wolter performed an Oaxaca-Blinder decomposition of this change for 1st-generation migrants to see what was up. Their result was really something.

In the year 2000, immigrants' parents being from Germany, France, Austria, or Belgium predicted +24.80 points on the PISA (ns). If they were from Italy, Spain, or Portugal, -2.46 points (ns). If the immigrants were from Albania, Kosovo, or other parts of ex-Yugoslavia, the effect was -27.39 points. Immigrants from Turkey were associated with -38.35 points!

Moreover, a person's parent having a tertiary education was associated with a 30.84 point boost in PISA scores (ns), while compulsory education was associated with a decrement of -26.40 points.

But after Switzerland started letting in immigrants of all skill levels instead of just low-skilled immigrants, things changed. For example, if a person's parents were from Germany, France, Austria, or Belgium, that was associated with +51.41 points. Being from Italy, Spain, or Portugal was associated with just -0.18 points (ns), while parentage from Albania, Kosovo, and ex-Yugoslavia came with -11.48 points. Being from Turkey was also no longer a negative, as it was associated with +9.50 points (ns).

Not only that, but education also became less apparently meaningful. For example, tertiary education was associated with only +10.99 points, and compulsory education with +4.58 points (ns). Perhaps the increased diversity in migrants' qualifications helped erode the signal from this sort of variable.

Regardless of the reason, it seems that almost 75% of the 40-point increase in 1st-generation immigrants' scores was attributable to this unusual change in migration policy. Or, as the authors put it: "Better migrants, better PISA results."

This just may be one of the most powerful things you can learn for invention and creativity.

Thomas Edison kept it a secret and even had a statue he designed to be placed on his estate to memorialize it.

I began to studied it in the 1970s after visiting Menlo Park.
