Well no one has a plausible explanation on it yet but with some of the highest A/B testing ratio and best Data Scientist Amazon too seems to think this works.
Hah. I remember shopping for a wireless router and seeing things like “shoppers who bought this item also bought...”. Yes, we all buy three slightly different models of routers. Good job Amazon.
Actually there is. There is a certain chance that you're unhappy with your fridge and you'll return it. So the assumption is that you are more likely to buy a different fridge than any other item. That's why they show you other fridges.
