You may be right (and that’s a thing I hadn’t considered, thank you!) but I worry that getting it wrong means you’re adding to noise and masking the message underneath a veneer of familiarity (how many compulsive gamblers see the “Gambling problem?” message at the bottom of casino billboards? How many smokers read the surgeon general’s warning?).

To get that calibrated correctly, you’d need some research; but the data on why a person searches a particular search term is definitely going to be skewed in this instance by a flood of people searching these two terms to compare the results.
