Quantifying IQ is hard enough - quantifying deltas based on subjective rates of poverty? That'd be a courageous goal. Authors set out to demonstrate qualitative cognitive differences between people suffering with scarcity (primarily cash) and those not. People suffering with scarcity have a cognitive load that the 'not' category does not -- I don't think that translates to reduced IQ, but was demonstrated to translate to 'more bad decisions' via heightened and persistent cognitive load. ADDENDA: From the outside looking in, that phenomenon may be misunderstood by an observer to indicate a causal relationship between bad decision making and poverty. TFA makes the case that causality is inverse to common (by governments, elites, etc) interpretation.
