什么是“默认选项”的威力——opt-out 为何胜过 opt-in？
What is the power of defaults—why does opt-out beat opt-in?
默认选项利用现状偏差与惰性：被预选的方案采纳率远高于需主动选的。它广泛用于器官捐献、节能与订阅，是“助推”的核心工具，也引发家长式干预的争议。
Defaults exploit status-quo bias and inertia: pre-selected options are adopted far more than those needing action. Used in organ donation, energy saving and subscriptions, it is core to 'nudging,' with paternalism debate.

什么是“心理账户”？钱为什么不都是等价的？
What are mental accounts—why isn't money all equal?
心理账户指人把钱按来源/用途分账（奖金、工资、彩票），对不同账户消费倾向不同，违背钱等价。它解释为何舍得花“返现”却省“工资”。
Mental accounting splits money by source/use (bonus, salary, lottery), spending each differently despite equal value. It explains splurging 'cashback' while skimping on 'salary.'

为什么“免费”最贵——零价格效应？
Why is 'free' the most expensive—the zero-price effect?
“免费”会不成比例地吸引选择，因省钱的快感压过理性权衡（零价格效应）。结果人们为免运费凑单、拿无用赠品，反而多花。
'Free' attracts choice disproportionately as the pleasure of saving overrides reason (zero-price effect). People add items for free shipping or grab useless gifts, spending more.

面对三档价位，为什么很多人偏偏选中间那档？——折中效应
Facing three price tiers, why do many pick the middle—compromise effect?
折中效应：在不确定时人们倾向选中间档以求“安全不亏”，看似理性实为回避极端。商家用高低两档夹出中间“主推”款即是利用它。
Compromise effect: when unsure, people pick the middle to seem 'safe, no loss'—rational-looking but avoiding extremes. Sellers flank a target with high/low to make the middle the hero.

菜单上放一个超贵套餐，会让中间那款显得划算——这是什么效应？
A pricey menu item makes the middle look like a deal—what effect is this?
诱饵效应：加入一个明显次优的“诱饵”选项，会改变对其他选项相对价值的判断，使目标项更受欢迎。商家用它引导选择，识破它要看“我真的需要吗”。
The decoy effect: adding an obviously inferior 'decoy' shifts perceived value of other options, making the target look better. Sellers use it to steer choice; seeing through it asks 'do I really need this?'

为什么“限时/限量”会催人下单？——稀缺效应
Why do limited-time/quantity offers push us to buy—scarcity effect?
稀缺（限时、仅剩N件）触发损失厌恶与紧迫感，降低理性比较。它常是营销制造，冷静后问“没有这紧迫我还买吗”可防冲动。
Scarcity (deadline, only N left) triggers loss aversion and urgency, cutting rational comparison. Often manufactured, a calm 'would I buy without this rush?' curbs impulse.
