So with the CSII and it's 2 dimensions, the normative and the informational, you have a way to measure it's influence on purchase intention. If with the informational dimension you measure one's inclination to accept information from others as a validation of reality, you are thereby influenced and your intention is changed. So if I measure high on the scale I will be very influenced to buy. But can't this dimension used to measure anything else? If I measure a price variable, can't it influence it too? If I am verys susceptable to price and I score high on the informational dimension, can´t I assume that for that particular variable I am very susceptable to be influenced, therefore if anyone wanted to influence me via marketing all they had to do was press that matter?
I had the base from somewhere but stupidly didn't take note of it and I am unable to replicate the search.
