1) One ramification of the fact that attitudes are hypothetical constructs is that we must infer their existence from people's statements and behaviors.
2) Since attitudes are unidimensional constructs, they can be measured along a continuum.
3) The third assumption may be the most critical - that attitudes and behavior are related, but that the relationship is much more complex than researchers originally thought. In the field of social psychology, the work of Ajzen & Fishbein (1970, 1973, 1974, 1977) is frequently cited as a theoretical framework concerned with attitude formation, behavioral intentions, and the prediction of overt behaviors. In general, research findings support the framework.
