Furthermore, the Hierarchy of Needs has been accused of having a cultural bias—mainly reflecting Western values and ideologies. From the perspective of many cultural psychologists, this concept is considered relative to each culture and society and cannot be universally applied. However, according to the University of Illinois researchers Ed Diener and Louis Tay, who put Maslow's ideas to the test with data collected from 60,865 participants in 123 countries around the world over the period of five years (2005-2010), Maslow was essentially right in that there are universal human needs regardless of cultural differences, although the authors claim to have found certain departures from the order of their fulfillment Maslow described.
