It's important to separate objective self interest (knowing all the facts combined with perfect reasoning) and subjective self interest (based on limited and likely misleading data, with possibly faulty reasoning). The first one will obviously not be true for the most part and is usually only knowable in retrospect, but aside from some amount of purely random decisions, the rest will largely fall in the second group, if only subconsciously. But I'd argue it's still the same exact principle :P
