Anchoring Effect / 锚定效应
Anchoring effect is the pull that an initial number or frame has on later judgment. In 106.别再害怕冲突，快来学习谈判术！, the first-offer question is treated as conditional: making the first offer can set the anchor when one has good information, but letting the other side go first can reveal their expectations.
The episode uses a real-estate valuation experiment to show that even professionals can be influenced by nearby listed prices while denying the influence. It also suggests extreme counteroffers as a way to offset an extreme anchor, while warning that the counter must be managed carefully so the negotiation does not collapse.
《资治通鉴·秦纪》116｜史上最惨太子：被父王亲手斩杀？！ adds a historical command-selection case. When 嬴政 / 秦始皇 asks how many troops are needed to conquer 楚国, 李信 first says 200,000 will suffice; 王翦 later says 600,000 are necessary. The source treats Li Xin’s lower first answer as the anchor that makes Wang Jian’s larger estimate look aged and timid rather than appropriately cautious.
《资治通鉴·秦纪》117-2｜学着点！秦朝武将竟然如此高情商？ gives the outcome of that command anchor. Li Xin and 蒙恬 initially win cities, but 项燕 defeats the expedition near 南郡, forcing Ying Zheng to return to Wang Jian’s 600,000-troop requirement. The episode therefore treats anchoring not as a small judgment quirk but as a strategic-scale planning error that must be corrected after battlefield loss.
Key Claims
- Anchors work partly because later judgments adjust from the first salient number.
- Expertise does not eliminate anchoring pressure.
- First offers are useful only when they are backed by enough information about Zone Of Possible Agreement / 协议区间.
- Counter-anchors need explanation and emotional buffering to avoid damaging the relationship.
- Anchors can distort military and managerial judgment as well as bargaining: a lower first estimate may make a larger realistic estimate look like fear or incompetence.
- Later evidence can break an anchor, but the correction may come only after the underestimated cost has already been paid.
Connections
- Reservation Value / 谈判底线 and Zone Of Possible Agreement / 协议区间 - anchors can distort these estimates.
- Concession Signaling / 让步信号 - later concessions also signal where the parties may be anchored.
- Behavioral Investing Biases - existing wiki branch where anchoring also appears in investment decisions.
- Motivated Bias / 动机偏差 - related bias that can make people deny being influenced.
- Qinji 116, 李信, 王翦, 嬴政 / 秦始皇, and 楚国 - troop-estimate anchor in the Chu campaign decision.
- Qinji 117-2, 蒙恬, 项燕, and 南郡 - battlefield correction of the underestimated Chu campaign.
