Definition: Adherency is the ability to accept, respect, or comply with the demands or wishes of another person or group. For instance, a student who follows a strict schedule for school work is adherent to their teacher's instructions, while an employee who stays on time and does not cause any disruption at the workplace is considered obedient. Adherency also means remaining consistent in doing something even when there are conflicts or challenges that may arise, as demonstrated by individuals like Einstein who did his utmost to avoid conflict with his fellow scientists.
