The issue is in the combination of data. Could you imagine the value of knowing if your heart rate went up after reading a certain message, or seeing a certain ad?

I don't care about the value.

What's the cost?

We can’t know the cost without knowing the value. Nothing will happen to the data unless someone buys it.

To identify the costs, we’ll have to think about who might want to purchase this data and what they could do with it.

Ask yourself this: why would anyone be willing to pay for your heart rate?

No, I'm guessing it's worth a couple of cents ?

Perhaps. But this kind of psychographic profiling is used in labs to craft better adverts. Video games are another example.

The Left 4 Dead director was trained on player emotions and designed to improve the game, which was a huge success.

Having access to it in the field has real applications.
