Why are Ads Filled with Fake Science?

In high school I had a great teacher named Mr. Dougherty who opened my eyes to the way advertisers manipulate our lack of scientific knowledge.
Mr. Dougherty said, "Shampoos will often say, 'PH balanced for your soft skin' or something like that. What they're not telling you is that every shampoo has to be PH balanced because otherwise it would burn your skin."

Since then I've had an eye out for deceptive ads that state the obvious as if it's something novel.
And one ad caught my eye yesterday on the subway. It's an ad for "AIRism" a new product from Uniqlo which for some reason is named like a religion.

I just love the part of the sentence where it says that Airism is "engineered specifically for both men and women."
That is actually not specific at all.
If Airism is for men and women then it's engineered specifically for every human on the planet.

It's like someone asking me what kind of women I like and me saying,
"I specifically like short and tall women, fat and skinny women, and specifically the women that have boobs."

What's not shown in this picture is that the Men's and Women's descriptions are slightly different descriptions of the same effects.

Be skeptical of science in ads people, cause remember:
They're just trying to sell you something.
