on the intelligence of users, usability, and the law of reciprocity in application design
Users are not stupid, but often very busy so that they ignore warning labels, buttons and obvious passages. It is up to the designer to cut the noise down and reduce clutter. The best design is non-obstructive.
A tiny fraction of people will always fail. It is up to the designer to rescue them — a beneficiary gesture. Empowerment leads to soaring individual intelligence, and only with empowering the users can everybody benefit.
This is very obvious.
