The only way to maximize group creativity—to make the whole more than the sum of its parts—is to encourage a candid discussion of mistakes. In part, this is because the acceptance of error reduces cost. When you believe your flaws will be quickly corrected by the group, you're less worried about perfecting your contribution, which leads to a more candid conversation. We can only get it right when we talk about what we got wrong.

Children can't help but create: they need to put their mind on the page, they want to paint, to sculpt, to write short stories.

Creativity is a catchall term for a variety of distinct thought processes.

Creativity is not a trait that we inherit in our genes or a blessing bestowed by the angels. It's a skill.

Design is the conscious imposition of meaningful order.

How do we regulate our emotions? The answer is surprisingly simple: by thinking about them. The prefrontal cortex allows each of us to contemplate his or her own mind, a talent psychologists call metacognition. We know when we are angry; every emotional state comes with self-awareness attached, so that an individual can try to figure out why he's feeling what he's feeling. If the particular feeling makes no sense—if the amygdala is simply responding to a loss frame, for example—then it can be discounted. The prefrontal cortex can deliberately choose to ignore the emotional brain.
