Some people would ask, as a data scientist are you upset that the data actually failed you. Not really.

It is a failure to rely too heavily on one or the other. You need to question everything. The data as well as our cognitive biases.
When it comes to wearables, Is “10,000 steps walked today” actually just a vanity metric? Will it really make me change my behavior and lose weight? It is all still too bleeding-edge. Like the early days of business analytics, are we still just presenting data to people rather than giving them meaningful metrics that will change behavior.
