Yep, read the paper. But am very uncomfortable calling this a decision bias. It's more specific than that. It's about aversion of risk and how framing a decision in loss terms vs gain terms leads people to decide differently(see
https://en.wikipedia.org/wiki/Anchoring). Otherwise i agree the bilingual subjects do display the bias in their native tongue. Am gonna try reasoning in all three languages i know and see how that affects my decision making :-P
