Democracies tend to have lower levels of corruption
This scatter plot illustrates the relationship between political corruption and electoral democracy indices for various countries in 2024. The vertical axis represents the political corruption index, ranging from 0, indicating less corruption, to 1, indicating more corruption. The horizontal axis shows the electoral democracy index, also ranging from 0 to 1, where higher values suggest greater levels of democracy.

The chart is titled "Countries that are more democratic tend to be less corrupt" 

Each country is represented by a point on the graph, with countries like Denmark and Singapore positioned closer to the lower end of the corruption scale and higher on the democracy scale, indicating they are less corrupt and more democratic. In contrast, countries like Myanmar and Russia are closer to the higher end of the corruption index. 

The data is sourced from V-Dem, with estimates based on expert evaluations. The chart is licensed CC BY to Our World in Data.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants
