Psychology is a discipline with global influence, but continues to neglect disadvantaged minorities and continues to adopt an incorrect model of science. This volume explains what has gone wrong, and what steps should be taken for psychology to become a constructive international force. Historically, psychologists have focused only on causal explanations of behavior, neglecting normatively regulated behavior and intentionality. By giving greater importance to context and collective processes, moving from 'societies to cells,' psychologists can better understand and explain individual behavior. Poverty is an extremely powerful context that shapes cognitions and actions, with destructive consequences for disadvantaged individuals. The advocation of 'be happy psychology' and 'resilience' as solutions to problems faced by the disadvantaged leads to entrenched group-based inequalities, with the poor stuck at the bottom. Moving forwards, this volume proposes that psychologists should focus on normative systems to ultimately foster a more balanced field of study for the future.
