“Facebook’s strategy, as he described it, was not so different from Napster’s. But rather than exploiting weaknesses in the music industry, it would do so for the human mind. “The thought process that went into building these applications,” Parker told the media conference, “was all about, ‘How do we consume as much of your time and conscious attention as possible?’” To do that, he said, “We need to sort of give you a little dopamine hit every once in a while, because someone liked or commented on a photo or a post or whatever. And that’s going to get you to contribute more content, and that’s going to get you more likes and comments.” He termed this the “social-validation feedback loop,” calling it “exactly the kind of thing that a hacker like myself would come up with, because you’re exploiting a vulnerability in human psychology.” He and Zuckerberg “understood this” from the beginning, he said, and “we did it anyway.”
