ABSTRACT
Recent arguments claim that behavioral science has focused - to its detriment - on the individual over the system when construing behavioral interventions. In this commentary, we argue that tackling economic inequality using both framings in tandem is invaluable. By studying individuals who have overcome inequality, "positive deviants," and the system limitations they navigate, we offer potentially greater policy solutions.

Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups. We tested temporal discounting and five intertemporal choice anomalies using local currencies and value standards in 61 countries (N = 13,629). Across a diverse sample, we found consistent, robust rates of choice anomalies. Lower-income groups were not significantly different, but economic inequality and broader financial circumstances were clearly correlated with population choice patterns.

Ultrafilters (dialysis membranes) are generally considered to be impermeable to bacterial endotoxins (lipopolysaccharides) contaminating dialysates used for hemodialysis therapy, due to the self-aggregating properties of its molecules in aqueous media. The aim of the present investigation was to monitor the efficiency of high-flux polysulfone ultrafilters in removing lipid A and lipopolysaccharide (LPS) from dialysis fluids. To evaluate the safety of high-flux polysulfone membranes, an in-vitro circulation system (measuring lipopolysaccharide and lipid A penetrate from the ultrafilter to the other side and vice-versa), was utilized. Peritoneal dialysis solution was spiked with various concentration of Pseudomonas aeruginosa lipopolysaccharide (LPS) as well as lipid A diphosphoryl (E. coli F-583). Endotoxin and lipid A concentrations were detected by a chromogenic limulus amoebocyte lysate (LAL) assay. This investigation indicates that polysulfone ultrafiltration represents an efficient system to obtain an endotoxin and lipid A free dialysate when contaminated peritoneal solution was circulated through the dialysis membrane.
