Don’t Know Whether to Push or Pull? Blame the Design.
2016-07-11
Over 95% of people pull this door.
100% push this door.
Actually, you cannot pull this door, can you?
People do that their guts tell them to do. "Push" or "Pull" ... If you need a instruction, the door is designed poorly.
Same for the software. If you designed well, there is no need for an instruction. People do what people do. We need to understand ourselves and design the software accordingly.
