In this eighth and final installment of the Expert Commentary series from the BIAS project, Marianne Bertrand talks about the potential for a “broader behavioral agenda” that would include larger contributions from psychology and could transform public policy.
The BIAS project offers overwhelming evidence that insights from the behavioral sciences can be successfully leveraged to improve access to human services among the poorest and most vulnerable families in the United States.
