同学,你好:不一样,the individual’s subjective expected utility is Σu(xi)P(xi)。Statement 1, beliefs are being updated 是基于 heuristics 启发式的,而不是 Bayes’ formula. Statement 2 一致与 prospect theory(权重分配不同); the client is overweighting the probability of a high financial impact outcome (gains on options) and underweighting the probability of a loss (the option premium cost).Statement 3 一致在于前提都是 risk-averse 的(风险厌恶)。

同学,你好:Heuristics are mental shortcuts based on experience and knowledge that simplify decision making. They are sometimes called “rules of thumb.”其实就是基于经验法则去做判断(直觉)。
