The current paradigm is so thoroughly established that the only way to change is to start over again.

I think there is a tendency in science to measure what is measurable and to decide that what you cannot measure must be uninteresting.

In my opinion, no single design is apt to be optimal for everyone.

Design is really an act of communication, which means having a deep understanding of the person with whom the designer is communicating.

I think a successful company is one where everybody owns the same mission. Out of necessity, we divide ourselves up into discipline groups. But the goal when you are actually doing the work is to somehow forget what discipline group you are in and come together. So in that sense, nobody should own user experience; everybody should own it.

Technology may change rapidly, but people change slowly. The principals [of design] come from understanding of people. They remain true forever.

If people keep buying poorly designed products, manufacturers and designers will think they are doing the right thing and continue as usual.
