I could ask as an opt-in as it would be interesting for sure
You hear a lot of things (both positive and negative) about various countries and their education, it would be interesting to see some actual data.
One unsurprising trend I have noticed is that countries that value education more highly, put more effort (and more money) into it.
Collect user-generated data (drawings, answers) through games and interactive pages, then measure the results and compare to open data sets or against common conceptions
I created "Borderline", a border drawing game a few weeks ago.
Since then, thousands of people have played it and I have accumulated over 37,000 drawings, which are now all stacked on a blank canvas.
This allows you to see the world as people remember it.
You can also check similar maps for the US, France, the UK, Germany, Australia, and Switzerland.
Alternatively, you can also draw a few borders yourself (free, no signin required)
What people are drawing isn't the "truth" on average. First, nobody has seen the world from actual far away (space) and is just using what they remember from school or other media. And second, there is no "truth" because we are fundamentally dealing with a 2d projection of the 3d surface of a sphere and there are many different projections, all with advantages and disadvantages, neither being more correct than any other.
For some "narrow stripped" lands, that’s not that surprising, that lines also overlap so much in the middle, but for some countries with very distant straight lined boundaries, it’s far more astonishing. Some really looks like "drow some random strokes" was the sole instruction.
For a country like China, whose neighboring countries do not use the same language, you can get a reasonably good guess as to its borders simply by drawing in the space between city names written in hanzi and nearby cities without those names.
