I do not fully agree. Take into account the fiscal pressure, here is the same. Another thing is that basic investigation is a waste of time if you do not have capacity of developing the possible outcomes from it. So, first develop more in what generates employment, and the current research should be only related to what generates employment and not in what generate easy papers (scientific articles). If not you end doing things that in the academic sense is good, but is of not use. You have to growth your GDP with good investment, it mean, good research too and then expand the expenses in research

This is a good example of why I think any visualization of correlation should include the actual Pearson correlation value. I don't think the correlation here is a strong as the title makes it out to be (wouldn't be suprised if < 0.5), even setting aside concerns about whether it is spurious.

It’s also a great example of development with little to no exportable natural resources. You’re not dependent on climate, or your neighbours. An R&D industry also enables startups, which leads to global companies forming that provide unique solutions you can’t get elsewhere giving you leverage on the world stage. Large companies start opening HQs in your country.

No, you can have it in datasets of any size. If X causes Y, but also it just happens that in your dataset there's some other factor Z that causes (not Y) and happens to correlate strongly with X (in your dataset). For example, if exposure to some substance causes cancer, but people who are exposed to that substance tend to be exposed to vast quantities of it that kill them immediately (thereby preventing the vast majority of them from living long enough to develop cancer), you'd have a definite causation, but no (or even a reversed) correlation.

The Saarland has a population density of 382. However, regardless of the actual density, every dense region will look completely red. It's just that Germany has no large uninhabited areas whereas the Alps in Switzerland are almost uninhabitable.
TLDR: Switzerland's network is denser, it just has bigger holes
