What might link these
The relationship between public sector corruption and political rights might be driven by the fact that countries with stronger political rights tend to have better institutions and mechanisms for holding officials accountable, reducing corruption. A careful reader should be cautious about assuming causation and consider other factors that could influence this relationship, such as education levels or press freedom. Economic development is a likely confounder, as it can impact both corruption and political rights.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. This correlation could mislead by implying a direct causal link between reducing corruption and improving political rights, when in fact other underlying factors may be driving both.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
