I want to test an idea about how the perception of decision making process alignment with another party influences the tendency to accept information from that party. For example, if my wife and I both consider the cost, nutrition, and the presence of a toy when considering breakfast cereals, I'm more likely to take her cereal recommendation when I go to the grocery store. Likewise, if somebody else only considers taste, I'm less likely to heed his advice.
Looking in the literature, I can't seem to find any measures of decision making process alignment between two people. Does anybody know of a related construct that has been validated?
