A taxonomic approach to field research was developed and utilized to support empirical and experimental research findings into the impact that incentives/pressures to overvalue have on systematic valuation bias. An expected no‐bias population was defined and valuation judgments from actual, real‐world appraisals were statistically tested against it. The judgments of appraisers presented with no incentive/pressure to over‐value were consistent with the no‐bias population, while the judgments of appraisers presented with incentive/pressure to over‐value were significantly incompatible with the defined no bias population.


Taksonomijos metodas buvo išpletotas ir pritaikytas taikomajam tyrimui siekiant patvirtinti empirinius ir eksperimentinius tyrimu rezultatus, kad paskata arba spaudimas pervertinti yra sistemine paklaida. Buvo apibrežta tiketinoji nešališka imtis ir nustatytos statistines realios vertes. Vertinimai, kuriuose nebuvo paskatos ar spaudimo pervertinti, buvo suderinti su imtimi be sistemines paklaidos, o vertinimai su paskata ar spaudimu pervertinti buvo visiškai nesuderinti su apibrežta imtimi be sistemines paklaidos.
