We live in a world so diverse and so complex that everyone has to deal with situations where we’re really don’t know what’s going on. We have to ‘drive blindly’ – we’re all dummies at some time or another.
The reality is, it’s rarely your fault.
The last person said to know everything about the world was John Stuart Mill. In the 137 years since his death, no-one else has achieved that feat.
Instead, it’s the responsibility of the provider of a product or service to recognise that some of their users will be ‘dummies’. It’s their responsibility to find ways to make their customers capable and aware of what’s going on.
This is why good usable design, training, user documentation and other forms of user assistance are so important.
