Self-Identity and the Theory of Planned Behavior: Assesing the Role of Identification with" Green Consumerism"

deep look at self identity and whether it is an independent variable in the formation of intention.
the authors seem convinced that it is not independent, but rather an antecedent to attitude.
they tackle the articles claiming that it is independent and carry out research of their own.
they kinda come to the conclusion that it is independent (grudgingly) but point out that other authors do not apply A + F 100% accurately.
good intro to self id.
You want to do A, and you should do A (B), but you are the sort of person who does C.
