This is not really true. Consumer confidence has a direct impact on GDP in terms of consumption. Lower confidence = lower consumption. Other components of GDP (Investment, Government spending, Net exports) can increase at the same time which can result in no net change, or even positive growth despite decreases in consumer spending. But saying consumer confidence (ie consumption) has no correlation with GDP is incorrect. This is basic macroeconomics.
