Socialist countries did great in 2022

Two weeks ago the Human Development Report 2023/24 was published. As I did last year, here's a comparison of current and past socialist and capitalist economies' HDI (not weighed), along with the standard error of the latter group and a p-value computed via Mann-Whitney U-test.

Looks like socialist countries are now (in 2022) fully on par with their capitalist counterparts. All of them except Cuba saw a sharp increase in their HDI, while capitalist countries are yet to recover from the COVID-19 pandemic and its economic consequences.
