Acceptance in human psychology is a person’s assent to the reality of a situation, recognizing a process or condition without attempting to change it or protest it. In the case of ReVeAL, we are interested in the distribution and aggregated levels of acceptance of an entire population or homogeneous groups within that with regards to specific UVAR policy interventions. Acceptance can be measured and normally changes over time. Acceptance may be affected by specific design characteristics of UVAR policy measures, personal characteristics, and opinions of others.
