People are more influenced by options that are put into a larger group
Description
Category size bias describes our tendency to believe outcomes are more likely to occur if they are part of a large category rather than part of a small category, even if each outcome is equally likely.
We mistakenly believe that items in larger categories have a higher probability of being picked than the ones from smaller categories.
Example
Just because most of the contestants in ski jumping are from Norway, doesn't mean the sportsman from Norway will win the whole season.
Nonetheless, because of category size bias, when seeing the majority comes from Norway, the one from Norway will be your favorite.
Application
Featured Products and Bestsellers
Highlight products or services from larger categories prominently on your website or in digital marketing materials. Use labels such as "Bestsellers" or "Most Popular" to emphasize their popularity within the broader category. This can create a perception of desirability and drive interest among consumers.
Bundle Offers and Packages
Create bundle offers or packages that include products from larger categories alongside those from smaller categories. By pairing items from different categories together, you can capitalize on the perceived popularity of the larger category to increase the perceived value of the entire bundle.
