I can't be the only person afflicted with these sidebar ads. The series is notable for taking guys who have at most 7% body fat and then Hulking them out even further through some form of isometrics or meditation or whatever. They doubled down on whatever game they're running, though, with this particular before/after set. You have to imagine it animating back and forth between the two:
The deceit here is vaguely mathematical so I asked my first class of students, "What is it selling and how does it try to sell it?" Most identified the product as some kind of weight loss formula and/or protein shake. No one identified the deceit.
So I asked my next class, "What is it selling and how does it lie?" Many suggested we were looking at two different people here, which I said was false (with about 99% certainty). One student thought the ears were the giveaway, which is true, though not the giveaway he thought they were.
I guess I'm curious a) if you notice the deceit and b) if there's any way to translate that deceit into an actionable math unit?
Update: Yeah, it's the distortion, which is about 17% too wide in the first image and 17% too tall in the second image. Should it worry me that none of my students caught it?
Here are my estimations of the undistorted images.
Graph: effectiveness of ad v. percent distortion.
[Update: Holy cow. They fixed the proportions in the latest ad buy.]
