A few years ago, everyone was clicking. Today, we’re all scrolling. Twitter, Pinterest, Facebook, and as of this week, Instagram and Medium - it seems everyone is getting on the infinite scroll bus. What is it about this magical design pattern that has so many consumer web companies using it?
Not too long ago, users were forced to reload pages to progress from one piece of content to the next. Web designers were advised against creating websites with information appearing “below the fold”, the portion of the page underneath what is displayed on the screen. As mobile phones and tablets gained wider adoption, it looked like the swipe might become standard fare. But that’s all changed now. Today, designers are dumping the click and flick and opting for the scroll for one simple reason – it works.
The Endless Search
The infinite scroll is interaction design’s answer to our penchant for endlessly searching for novelty. Certainly, there are technical reasons for the scroll’s increasing ubiquity. The rise of dynamic content, like a new comment entering the feed, necessitated a better solution than pagination built for static content. But to really understand why the scroll works so well requires a brief trip inside the mind and back in time.
Our brains evolved through the millennia into incredible prediction machines, designed to help us make sense of our environment. Our species benefited from our ability to make good decisions based on what we know is likely to happen in the future, thus, keeping us alive long enough to make babies and spread our genes.
