Alan Cooper:

Cain devotes most of her text to casting doubt on the millennial generation’s tendency to do everything as a group. Schooled early in the political correctness of what she calls “groupthink,” young people seem inclined to attack everything as a large collaborative team. I’m a big fan of teams and teamwork for getting most things done, but for innovation, give me just two people, a whiteboard, and the challenge of a Gordian Knot to untie.

I found myself nodding along in agreement to most of the points here. Some of my most productive work has come when working with one other person in front of a whiteboard. Knowing group dynamic, there is a natural flow to how those things work and “roles” that people take on, and it’s simply to difficult to think critically in those situations.

More isn’t always better:

Brainstorming’s adherents believe that a group of people can together imagine more and better solutions than any one person can alone. I won’t dispute that assertion, but just because one is better than the other doesn’t imply that either is anywhere close to being optimal.

I like the idea of small teams of two smart people working on a problem.
