It is not best that we should all think alike;
it is a difference of opinion that makes horse races.

All Kinds of People                                              

In my close to 40 years in software, I've seen a lot of different kinds of people working in the business.  In the early days (that would be the 1970s), in the North of England, the company I worked for hired Physics and Math majors like me, Mechanical and Electrical engineers, at least one Anthropologist that I know of (and write about in the the article).  Heck they even employed music majors to write software.

And this was not a bad thing...

The Difference                                                      

Scott W. Page's The Difference [Princeton University Press 2007] pointed out that collections of different thinkers usually perform better than even high powered groups of similarly oriented experts.  The reason is fairly straightforward: the best problem solvers often think quite similarly so there is little benefit in having more than one of them.  They can also engage in a nice comfortable groupthink which does not tend to explore different options and alternatives that might be more optimal.  Scott even asserts that ...diversity trumps ability.

He is not the only one to note this.  Edward DeBono years ago provocatively stated that smart people are often not good thinkers.  Specifically, he noted that:

Different People Think Different*                                 

There isn't much point in having too many people who think similarly.  Since they tend to come up with similar answers, there's not much benefit to having more than one of them.

Howard Gardner identified a number of different "intelligences" that are quite different ways of processing information.  They are:

As you can imagine, people with these different information processing modalities can come up with quite different answers when looking at the same problem.  Scott Page asserts that teams can create much more optimal and powerful solutions from hybrids of these answers.

If we have teams of different people.
