How does the belief that advertising drives major behaviour change square with 50+ years of psychological research showing that behaviour change is really difficult?

What on the face of those two statements is a conflict?

Long term behaviour change is difficult. Short term behaviour change; not so much.

To take a classic example from the "sociopathic" mind of Bernays himself:

> The targeting of women in tobacco advertising led to higher rates of smoking among women. In 1923 women only purchased 5% of cigarettes sold; in 1929 that percentage increased to 12%, in 1935 to 18.1%, peaking in 1965 at 33.3%, and remained at this level until 1977

And there's far, far more to it all. Sometimes you don't need people to change their behaviour, you just need them to be confused (say, about climate change, or who to vote for), and sometimes you just need media corporations to go soft on you because they like your money.

Sometimes you're advertising to kids, because childrens brains are more malleable. They form habits early.

Advertising made smoking cool; it made diamonds valuable; it greenwashed fossil fuel companies that sold our species future for short term profit. If you don't call that behaviour change, what do you call it?
