Why do older workers seem to have problems with technology? In this paper, I will review several possible reasons and illustrate them with evidence, often anecdotal, from our work as ergonomics practitioners. We find that older workers have more to "unlearn" from their accumulated experience. They may suffer from gradual or not so gradual ailing faculties of sight, hearing, dexterity, stamina, memory, and reaction time. They may exhibit a fear of making mistakes, and they may have strongly established preferences and pessimism about technological gimmicks. But the real problem is often that the designers have failed to anticipate the requirements of their users; they have failed to design for a range of abilities broader than their own; they have failed to test their designs with real people; and they have failed to learn from the experience of the market. Getting design right for older users is really only a continuation of getting design right for all.
