Anchoring heuristics influence decisions by making individuals rely heavily on the first piece of information they encounter.
Consider Tom, a first-time homebuyer who is looking for a residential property.
Jane, a homeowner, lists her house for $600,000 despite her real estate agent, Mark, advising that the market value is closer to $550,000.
Mark suggests the higher price as a negotiating tactic, but Jane becomes anchored to the $600,000 figure, believing her house is worth this.
When Tom visits the property, he finds it appealing but has a budget of $570,000.
The $600,000 anchor influences his perception of value, making him feel that offering $580,000 is a fair compromise.
Jane, anchored to her initial price, rejects the offer, viewing it as too low.
After some negotiation, Jane lowered her expectations slightly to $590,000.
Still influenced by their respective anchors, Tom and Jane struggle to agree.
Eventually, they settled on $585,000, which is above the market value but feels acceptable relative to their anchors.
锚定启发法是一种认知偏差,其中决策会受到所遇到的第一条信息的强烈影响,即使这条信息是任意或无关紧要的。这个初始参考点被称为锚点,即使在有更加准确或相关的信息的时候,它也会不合理地影响判断、估计和后续判断。心理学家认为,之所以会出现这种情况,是因为人们未能从锚点出发进行充分调整,这需要额外的认知努力。
