Stop blaming yourself for every digital mistake you make
In short: We have all been there: the forgotten email attachment, the wrong train ticket, or the accidental file deletion. While we tend to curse our own clumsiness, the fault often lies not with the user, but with the way our digital systems are designed.
When we struggle with a confusing website or a difficult ticket machine, our instinct is to take the blame. However, Professor Tony Mann suggests that the difficulty of navigating these interfaces is a central challenge for interaction designers. The frustration we feel—such as accidentally opening Adobe Acrobat when intending to use Photoshop—is often a symptom of design flaws rather than personal incompetence. This tendency to blame ourselves can actually create additional hurdles for the professionals attempting to improve these interfaces. This psychological habit makes the work of designers significantly more difficult.
The field of interaction design can be understood by connecting mathematical principles to the worlds of magic and illusion. By studying how humans interact with technology, designers aim to create systems that are both effective and comfortable to use. The goal is to reduce the frequency of common errors, such as the ubiquitous mistake of sending an email without its promised attachment. This study of human error is part of a broader series of lectures offered by Gresham College. This institution has provided free public talks to the community since 1597.
The stakes for these design choices are high. While some errors are merely irritating, others can lead to serious consequences. As computing power has grown—with modern smartphones now carrying more power than the most advanced computers from just a few decades ago—the complexity of the systems we rely on for cars, cameras, and navigation has increased, making the designer's role in preventing human error more critical than ever. The scale of this technological shift is immense, as we now rely on computing in everything from satnavs to cameras. Even the way we access knowledge has changed, as the internet and search engines provide information content that was previously unimaginable.
