alt Hacker NewsIs there a way to measure users "making the best choice?" You could measure the amount of time spent comparison-shopping, but most people are terrible at that anyway; it's an acquired skill for sure. Besides a willingness to spend time, it seems like an impossible-to-quantify metric even in the abstract.
Maybe the best proxy metric is whether the customer returns the product. But the store will also be willing to eat more returns on a higher margin item if they make more profit at the end of the day.
