A global study led by a researcher at Columbia University Mailman School of Public Health and published in the journal Scientific Reports finds that economic inequality on a social level cannot be explained by bad choices among the poor nor by good decisions among the rich. Poor decisions were the same across all income groups, including for people who have overcome poverty.
The association between the cognitive biases of the tested psycho-metrics and poor decision making with regards to socio-economic outcomes aren’t tested or even cited in the study. To draw a causal conclusion you would need to investigate and confirm that. Put simply, A does not imply B.
