In this TED video, Laurie Santos reminds us that humans are not perfect. Although we are really good at overcome our biological limitation, there are other limitations that we still need to address, such as our inability to be rational, the tendency to make errors and poor decision making. Therefore, until we recognise our own limitations we won’t be able to archieve in full our human potential. And here it comes the work of designers, Human Factors, and HCI researchers. We help people to achieve their full potential by recognise their limitations and design around them. A good designer can only be driven by love for people and the passion to improve the world.
