The main problem with the TPB is not that it is not explaining sufficient variability in behaviour. The main problem is that some of the theory’s propositions are patently false. In particular, the mediation assumptions in the TPB are in conflict with evidence. For example, beliefs are often found to predict behaviour over and above intentions. More critically, the bold sufficiency hypothesis assuming that all theory-external influences on behaviour are mediated through the TPB is empirically and conceptually indefensible, and has been falsified. For example, there is consistent evidence that age, socio-economic status, physical health, mental health and features of the environment predict objectively measured physical activity when TPB predictors are controlled for.
