Whether natural selection favours ‘cheating’ in mutualisms is hotly debated. Gano‐Cohen et al. (2019a) report a negative correlation between fitness and mutualist quality in rhizobia, suggesting that rhizobia evolve to cheat. However, reanalysis of their data shows that the correlation is an artefact of unequal sampling across populations.
