Lately I’ve noticed that more and more products — from gasoline to rewards cards to patent medicines — are being advertised by people in lab coats.
Somebody must have done a marketing study about this and determined that Americans just trust people in lab coats. How else to explain why companies who are trying to decide how to clothe the human mannequins that appear on billboards and point-of-purchase ads would pick lab coats as opposed to, say, a minister’s collar, a nurse’s uniform, or the loud sportscoat and gold-buckled loafers of a used car salesman? If my assumption is correct, why would people be more trusting of a shill just because he’s clad in a lab coat? Is it because a lab coat suggests intelligence and precision? Or, is it because lab coats have quasi-medical connotations, and people trust their doctors? I’ve known scientists and lab workers and they were decent human beings — but not measurably more honest or credible than people in other lines of work.
Often, the lab coat seems to have nothing to do with the product or service being sold. Consider the Shell rewards card ad that I saw when I fueled up my car today, a picture of which accompanies this post. It features a nerdy-looking guy in a lab coat gesturing toward the card. I guess he’s supposed to be a fun-loving Shell fuel technician . . . but why would anyone rely on a lab worker to provide them with guidance about smart financial decisions? Lab workers may be adept with Bunsen burners, but that doesn’t mean they know bupkis about whether a payment card is a good deal or a rip-off.
According to ABC News, 
I still balk, however, at the sale of product by presidential campaigns. Go to 
I’m sure such protestations of faith appeal to some voters, but for me they tend to set off alarm bells. In my experience, vendors who advertise their religious beliefs — say, with a cross on their Yellow Pages ad or a religious saying on the sides of their panel trucks — often turn out to be less than scrupulous. It’s as if such people use the overt religious symbols and sayings as selling points for their services, in an effort to entice the unwary. They appear at your house to give you a quote, sprinkle some Bible phrases or references to “the Lord” or “Christ Jesus” in their presentations, and hope that you let down their guard. And then, weeks later when the job has been done poorly or not done at all, you can’t reach them.
