Question

What is a strength and a weakness in a model?

Answer 1

The Health Belief Model (HBM) is a psychological model that attempts to explain and predict health behaviors. This is done by focusing on the attitudes and beliefs of individuals. The HBM was first developed in the 1950s by social psychologists Hochbaum, Rosenstock and Kegels working in the U.S. Public Health Services

WEAKNESSES:

they may not be accurate as climate models are highly complex  in number of factors and accuracy is lost in  the process of oversimplification, they depend on the expertise  of the people making them,and different people expound them  in different ways.
