“Proof” is one of those words that starts to seem funny if you look at it too long. Interestingly, our current understanding of the word only really took shape in the late 19th century, and its earliest etymology traces back to the Latin ‘probare’, meaning ‘to test’: Proof’s sexier sister-phrase, “Social Proof”, was first coined by , and it’s a key concept in one of his Robert Cialdini in his 1984 book, Influence six Principles of Persuasion : Reciprocity Commitment and Consistency Authority Liking Scarcity Conformity (Social Proof) Social Proof has since become a pretty ubiquitous umbrella term used by marketers, makers, product owners, and founders to describe any activity or feature designed to cue a given user behavior by highlighting the same behavior being performed by other users. As Hacker Noon writer Hojung Kim explains, in his story on , How to Engineer Viral Social Proof “[We knew we] could start from two first principles. Users will always respond to: 1. The right incentives — rewards or prizes to incentivize user actions; and 2. Social proof — following others taking the same actions.” In software, social proof is everywhere: from Amazon’s to the likes, retweets, comments and shares that power every social media platform that’s ever gained enough traction to stand the test of time. ‘Customers also bought…’ The Social Proof Challenge Robert Cialdini Didn’t See Coming The fact that is not new information. people and brands buy likes and followers Neither is the fact that social media has had a transformative effect on the evolutionary function formerly known as self-esteem.

Social media, with its displays of likes, friends, followers, and retweets, has pulled our sociometers out of our private thoughts and posted them for all to see. Human beings evolved to gossip, preen, manipulate, and ostracize. We are easily lured into this new gladiatorial circus.” What’s worse: according to a May NPR article entitled , “researchers culled through more than 200 million tweets discussing the virus since January and found that about 45% were sent by accounts that behave more like computerized robots than humans.” Researchers: Nearly Half Of Accounts Tweeting About Coronavirus Are Likely Bots So That’s Why Social Proof Kind of Sucks, Now What’s to be done about it?

We added time reading created on the profile page ( ): example 2. We added reads to the story page ( ): example And, this is why we’ve chosen to make these social proof related decisions: in the words of our CPO, Dane Lyons , "Social proof is one key element of the broader question: Some readers want a simple signal to help decide if a story is worth reading. And writers want a reward signal to help facilitate a virtuous writing habit. So simply adding a subtle number of story reads at the top of the post helps both the reader and the writer. What motivates people to engage with Hacker Noon? We haven't yet been able to invest as much energy as we'd like into social listening analytics or custom story commenting/reacting functionality. So stay tuned for more Hacker Noon social proof in the coming months."
