This was a scientific study with quantitative measures that have clear operating definitions as spelled out in their methodology section. I have trouble imagining the quantitative measurement for “Facebook designed their app to maximize addictiveness” would even look like. Have mercy on the poor scientists who chose to answer a narrow question empirically and well, and left the fuzzier question out of their scientific paper.

Not speaking about this particular study, just wanted to nitpick that the psychology tricks behind "Facebook designed their app to maximize addictiveness" have indeed been measured from the point of view of monetisation/engagement, hence why so many apps and games nowadays try to implement them. I agree the concept is not relevant for this particular study.

See the book "Hooked". This is not some batshit conspiracy, it's well documented
