Relative Estimation in 5 Minutes: Anchors and Comparisons

•

0 likes•642 views

The document discusses relative estimation versus absolute estimation. It notes that people are bad at absolute estimation but good at relative estimation when provided an "anchor" for comparison. It provides an example of estimating the value of a house, where providing different anchor values of $100k and $900k would likely result in very different estimates. The document is about a 5 minute presentation on relative estimation given by Stijn Decneut.
