I’ve compiled five academic research papers revealing the flaws of down-votes. Findings are summarized in bullet points for easy reading. Literature download link provided via WeTransfer for each.
In case their scientific merits are in question. These academic research papers are conducted/written by a team of postdoctoral scholars in computer science from Stanford University, in collaboration with Cornell University or Max Planck Institute. Their data-driven research via machine learning algorithms is supported and funded by their Stanford Graduate Fellowship and a Google Faculty Research Award, in cooperation with Disqus, Twitter, among many major commenting systems.
Studies such as these hark back to why major social sites across the field in the U.S. and China have abandoned the down-voting system, particularly the type used by our GoK.
-----------------
How Community Feedback Shapes User Behavior
we.tl/t-h9NZdGYkPm
- “We find that negative feedback leads to significant behavioral changes that are detrimental to the community”
- down-voting (negative evaluations) can “cause users to post lower quality contents,” or worse comments… and are perceived by the community as such, hence “valued less by others…”
- down-voted victims are more likely to subsequently evaluate their fellow users negatively by down-voting others, “perpetuating a negative feedback loop… a vicious spiral of increasingly negative behavior that is exactly the opposite of the intended effect.”
------------------
Antisocial Behavior in Online Discussion Communities
we.tl/t-3mRYEhCCno
- “Studying the evolution of these users from the moment they join a community up to when they get banned, we find that not only do they write worse than other users over time, but they also become increasingly less tolerated by the community. Further, we discover that antisocial behavior is exacerbated when community feedback is overly harsh.”

A few bad votes too many?: towards robust ranking in social media
we.tl/t-7jgWgbUTyR
- Susceptibility of down-vote abuse where increasingly, a “small fraction of malicious users are trying to game the system by selectively promoting or demoting content for profit, or fun.”
---------------------
Social Influence Bias A Randomized Experiment
we.tl/t-forItRx9wB
- Downsides of early down-voting by result in “snowball effect” of “irrational herding,” a “hive-mind” “mob mentality” of negative reinforcement.
----------------------
Anyone Can Become a Troll: Causes of Trolling Behavior in Online Discussions
we.tl/t-9e6z0eVR5T
- “ignoring bad behavior is an effective way of discouraging it, and one that social network sites might profitably explore. But at the same time, these sites will need a way to step in and actively prevent certain types of behavior when necessary.”... Permanent banning recommended, not negative reinforcing down-voting.
Remains of lost 1100 year-old city discovered in Yunnan
发布者One of the most groundbreaking archaeological discoveries was published only last month, suggesting modern human ancestors evolved not from Africa, but from China. The "Dali Skull" dating back to 260,000 years ago:

Kunming's bike share options: A user guide
发布者@GoKunming
300 meters, not 3km of damaged bikes:

Btw, two of the wealthiest CEOs in China have already invested in these companies. Alibaba is one of the lead investors in Ofo, while Tencent in Mobike. They are here to stay.
Years before these startups began, UBikes were proven to be a success in Taipei. These Chinese counterparts reversed engineered them into dockless shared bikes, which IMO are much more convenient for riders, albeit "tragedy of the commons" in the mainland ensued as expected.
Findings: Yunnan possibly once ruled by giant predatory otters
发布者via Google:
"Gray wolf weight varies geographically; on average, European wolves may weigh 38.5 kg (85 lb), North American wolves 36 kg (79 lb) and Indian and Arabian wolves 25 kg (55 lb). Females in any given wolf population typically weigh 5–10 lb (2.3–4.5 kg) less than males."
Okay, so these prehistoric otters are more massive... especially compared to the wolves (Canidae lineage) of the Miocene era:

Findings: Yunnan possibly once ruled by giant predatory otters
发布者@dolphin
Different epochs I presume. T-rex dinosaurs roamed the earth 60 million years before these giant otters.
"Bigger and more powerful than wolves?" WTF?! Look at that ferocious set of cutlery. So much for cuteness.
Just saw a Youtube video of a pack of tiny, adorable otters trying to take down a zoo keeper. Vestigial predatory instincts on full display.
