In social psychology, attitudes have traditionally reflected people's personal reasons and, thus, their personal behavioral propensities. Analogously, what later became a measure of environmental attitude was initially introduced as a measure of people's propensity to protect the environment. This classical view of attitude as a personal reason is of course ultimately justified only when one is able to reliably and consistently anticipate manifest behavior with an attitude measure, that is, if the notorious attitude-behavior gap does not really exist.
