Reliability and validity should not be seen as isolated concepts. In practice, they work together to produce research that is both replicable and meaningful. A highly valid instrument that lacks reliability would produce erratic results, undermining consistency in decision-making. Conversely, a reliable but invalid tool misguides with precision. Burns and Bush (2020) describe how establishing both attributes supports better interpretation of consumer behaviors, leading to stronger product development and market positioning.
