In device-independent quantum information, correlations between local measurement outcomes observed by spatially separated parties in a Bell test play fundamental role. Even though it is long-known that the set of allowed theory lies strictly Bell-local and no-signaling set, many questions concerning geometry remain unanswered. Here, we revisit problem when boundary coincides with simplest scen...

Abstract Commitment contracts are a strategy for binding self-control failures, such as skipping gym visit or breaking dieting regime, to monetary penalties. Despite evidence that commitment with stronger penalties improve self-control, they relatively underused. Across 5 experiments, we find decision makers less likely select more severe (i.e., anti-charity contracts) themselves than others. T...
