In Plain Sight
The image you see below is from the check-in process for my chiropractor, and I've seen this for more years than I can imagine. I have dutifully clicked on various descriptors and body locations each time, even though they change infrequently. But a few appointments ago, I noticed the option to choose "click here if you have no change in symptoms", which is a nice little time-saver.
According to the Perplexity AI chatbot, this is caused by two phenomena. The first is "inattentional blindness", which occurs when a person does not see something fully visible because their attention is focused elsewhere. The second is "selective attention", our brain's way of tuning into what matters and ignoring background distractions. All part of what it's like to be a human.
