You know 5-Hour Energy? You might have seen ads for it, some of which claim that this energy drink gives you a bigger boost of energy and focus than a cup of coffee. Another one tells the story of a guy who – after downing a 5-Hour Energy – disproves the theory of relativity, finds bigfoot, swims the English Channel (twice), and masters origami while setting a hacky sack record…all in 5 hours. Courts have determined that one of these claims is misleading enough that it violates marketing laws…this one, about the coffee. The ridiculous BS about the super-productive guy is totally fine. That’s because it’s a different type of marketing claim, known as “puffery.”
Here in the US, the legal definition of puffery has been honed basically into two subtypes: claims that are so wild that no “reasonable person” would believe them – like the 5-Hour Energy origami-bigfoot-English channel one – and claims that are so vague or subjective that they couldn’t actually be proven – like, say, a random diner claiming to sell the “World’s best coffee”. Companies argue – and courts agree – that consumers should be able to recognize these claims as bragging for the sake of selling us stuff, rather than as actual factual claims about the product. tSo even though there IS a system in place to protect us consumers from deceptive advertising – ad claims are just a really complicated issue. The bottom line is that you should still probably take most of what you see on TV – and, really, everywhere else – with a grain of salt…even when it comes to salt itself.
