The Kardashian index: a measure of discrepant social media profile for scientists. "In the era of social media there are now many different ways that a scientist can build their public profile; the publication of high-quality scientific papers being just one. While social media is a valuable tool for outreach and the sharing of ideas, there is a danger that this form of communication is gaining too high a value and that we are losing sight of key metrics of scientific value, such as citation indices. To help quantify this, I propose the ‘Kardashian Index’, a measure of discrepancy between a scientist’s social media profile and publication record based on the direct comparison of numbers of citations and Twitter followers."

Does the science world have its own version of the Kardashians? According to this article (written by a British geneticist Neil Hall, who himself has >1500 Twitter followers), certain scientists have way more Twitter followers than should be warranted by their publication records. To measure this effect, he invented the "Kardashian index", which is a metric similar to the h-index; however, instead of productivity, it measures the "discrepancy between a scientist’s social media profile and publication record." Certain scientists have very high "K-index" scores--that is, they're "renowned for being renowned." For those people, Hall
says,"[the K-index] can also be an incentive - if your K-index gets above 5, then it’s time to get off Twitter and write those papers."
