朝三暮四 (Zhāo Sān Mù Sì) — Three in the Morning, Four in the Evening
The Concept
English: Anchoring Bias — Relying too heavily on the first piece of information offered (the “anchor”) when making decisions; subsequent judgments anchored to initial values.
Chinese: 朝三暮四 (Zhāo Sān Mù Sì) — Three in the morning, four in the evening.
Cultural Origin
This parable from the Zhuangzi (庄子):
A man who raised monkeys said to them: “I will give you three chestnuts in the morning and four in the evening.”
The monkeys were furious.
So he said: “I will give you four in the morning and three in the evening.”
The monkeys were delighted.
The total was identical (seven chestnuts), but the monkeys anchored on the first number they heard. “Three” sounded insufficient; “four” sounded generous.
The Anchor as First Impression
Anchoring bias is the monkeys’ response applied to all judgment:
- The first price we hear for a product becomes our reference point
- The first impression of a person colors all subsequent interactions
- The first theory we learn about a topic becomes our default
- The first offer in a negotiation sets the range
The anchor doesn’t need to be relevant or accurate—it just needs to be first.
The Psychology of Sequence
Why does order matter so much?
- Cognitive laziness — The first number provides a ready reference point
- Adjustment insufficiency — We don’t adjust enough from the anchor
- Primacy effect — First information receives more attention and weight
- Framing — The same information presented differently produces different responses
The monkeys were not irrational—they were human. We all anchor.
Historical Manifestations
- The Tribute System: China’s first demand in diplomatic negotiations set the anchor for all subsequent relations. Barbarians who accepted the initial framing became vassals; those who rejected it became enemies.
- The Examination Pass Rates: The first year of a new emperor’s reign often set the anchor for what constituted “normal” success rates, influencing expectations for decades.
- The Opening Price: In traditional Chinese markets, the first price offered anchored the entire negotiation. Skillful bargainers knew to reject the anchor and establish their own.
Daoist Interpretation
Zhuangzi used this parable to illustrate the relativity of human judgment. The monkeys’ delight and anger were based on framing, not substance. The sage recognizes that all values are anchored arbitrarily and doesn’t cling to any particular frame.
Laozi taught: “有无相生，难易相成” (Being and non-being produce each other; difficult and easy complete each other). The anchor creates the perception of value; without the anchor, there is no high or low.
Modern Applications
Anchoring appears in:
- Pricing strategies where high initial prices make subsequent discounts seem generous
- Salary negotiations where the first number mentioned sets the range
- Legal damages where outrageous initial claims anchor jury awards
- Medical decisions where initial test results anchor diagnostic thinking
Each is three in the morning, four in the evening—same total, different reactions.
The Lesson
The monkeys teach that our judgments are relative to arbitrary anchors. The wise person:
- Recognizes when they are being anchored
- Actively generates alternative anchors
- Focuses on totals and substance, not sequence and framing
正如庄子所言：“名实未亏而喜怒为用。” (The reality was unchanged; only the emotions were manipulated.)
Seven chestnuts are seven chestnuts, regardless of when they are given.
