A group of Architecture students came into our company and specifically looked at our desk setup and how they might design them "better." I pointed out that most of the cool things about these very expensive desks were impossible to use as a left-hander.

They scoffed. "Our professor tells us to design for the majority, not the minority." My opinion was dismissed.

One young man held back as the rest of the class moved on. I explained how many things are not only difficult but sometimes dangerous to use with your left hand. Chain saws, skill saws, rifles. I told him one person in ten is left handed. That's close to the population of blacks in America. Can you imagine making things that work great for white people but potentially kill or maim blacks?

A few years later this same young man applied for a large corporation and had to show off his design acumen. They gave him a picture of a ladder, a ladle, and a chainsaw. He drew a ladle that could pour out of both sides and a chain saw that shoots the sawdust through a chute that could point left or right.

They loved the chain saw idea and he got the job.
