I think that point is highly focused on the decisions people would self report. I've seen studies where perception of a fictional brand is significantly increased through repeated banner advertising. I'm sure some high IQ participants in the study would report no impact, but have been influenced at a pre-verbal level. The psychology of repeated exposure is well documented.
