From Jean-Louis Gassée:
While persuading a consumer to buy a particular brand of suds seems banal enough, keep in mind the force of Facebook’s algorithms. In order to influence buying decisions, algorithms not only push consumers in a particular direction, they can steer them away from “unwanted” conclusions by injecting biased, partial information that subtly alters the user’s landscape and changes how a product is perceived.
This is something I think about a lot. We pretend algorithms are working to find the best result for OUR needs and forget that they are working to find the best way to generate revenue.
