A deficient product is a product that does not have immediate appeal and does not provide long-term benefits to the consumer and society. These products have neither immediate appeal nor long-term value (low satisfaction and low long-term benefits).
In the context of social marketing, this term is used to classify products that are ineffective and potentially harmful in the long run. Marketers, guided by the principle of social marketing, should avoid offering such products and focus on desired products that offer both high appeal and high benefits.
