“…This phenomenon is not rare; it is called denominator neglect, or ratio-bias phenomenon (in the present study I use the term denominator neglect). Denominator neglect is focusing on relative frequencies of numerators (Reyna & Brainerd, 2008), paying attention to numerators (number of times an event has happened) and inadequate attention to denominators (overall number of opportunities for an event to happen) (e.g., GarciaRetamero, Galesic, & Gigerenzer, 2010;Okan, Garcia-Retamero, Cokely, & Maldonado, 2011;Passerini, Macchi, & Bagassi, 2012), for instance, whether nine winning lottery tickets is few or many depends on the overall number of lottery tickets.…”
