Looks like even science magazines have fallen prey to clickbait titles a la buzzfeed. Which is quite sad considering that it's actually a quality article.
"Clickbait", especially "a la buzzfeed" also usually refers to the original definition: "10 great jokes that Shakespear hid in poetry–No 12 will blow your mind". And considering they have A/B tested their headlines and you consider the article worth reading, isn't the outcome arguably good, anyway?
