Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
Reverse chronology bias Once you’ve had a taste of effortless updates, it’s awfully hard to back to manual everything. So they didn’t. And neither did thousands of their peers. It just simply wasn’t worth it. The inertia was too strong. The old web, the cool web, the weird web, the hand-organized web… died. And the damn reverse chronology bias — once called into creation, it hungers eternally — sought its next victim. Myspace. Facebook. Twitter. Instagram. Pinterest, of all things. Today these social publishing tools are beginning to buck reverse chronological sort; they’re introducing algorithm sort, to surface content not by time posted but by popularity, or expected interactions, based on individual and group history. There is even less control than ever before. There are no more quirky homepages. There are no more amateur research librarians. All thanks to a quirky bit of software produced to alleviate the pain of a tiny subset of a very small audience. That’s not cool at all.
