An experiment using a representative survey of the German population shows that letting respondents report a number rather than asking them to choose from a list of predefined ranges lowers the response rate for both perceived past and expected inflation and decreases (increases) reported past (expected) inflation. Income, education, gender, objective and subjective knowledge about monetary policy, and political affiliation affect the effect's size but not its sign. East and West German respondents who were 15 or older when the Berlin Wall fell have reactions different from those who were younger at that time, which supports the ‘impressionable years’ hypothesis based on different inflation experiences.

一项对德国人口进行代表性调查的实验表明，让受访者报告一个数字，而不是要求他们从预先定义的范围列表中进行选择，会降低对过去和预期通货膨胀的响应率，并减少（增加）报告的过去（预期）通货膨胀通货膨胀。收入、教育、性别、货币政策的客观和主观知识以及政治立场影响效应的大小，但不影响其符号。柏林墙倒塌时年满 15 岁的东德和西德受访者与当时较年轻的受访者的反应不同，这支持了基于不同通胀经历的“易受影响年”假说。
