AIMING FOR A SCIENCE OF ALL HUMANITY To address p
Post# of 27283

To address potentially vast gaps in our understanding of human psychology and behavior, researchers have proposed a number of solutions. One is to reward researchers who take the time and effort to build long-term research relationships with diverse communities. Another is to recruit and retain behavioral scientists from diverse backgrounds and perspectives. Still another is to pay closer attention to the norms, values, and beliefs of study communities, whether they are WEIRD or not, when interpreting results.
A key part of these efforts will be to go beyond theories of “universal humans” and build theories that make predictions about how the local culture and environment can shape all aspects of human behavior and psychology. These include theories of how trading in markets can make people treat strangers more fairly, how some societies became WEIRD in recent centuries, and how the number of personality traits we find in a society—such as agreeableness, conscientiousness, neuroticism—depends on the complexity of a society’s organization.
Proponents disagree on the best paths to moving beyond WEIRD science to building a science of all humanity. But hopefully some combination of these solutions will expand our understanding of both what makes us human and what creates such remarkable diversity in the human experience.
