Caveat: written by Jonah Lehrer, whose star has fallen since it was shown that he recycled his own previous writing without noting it and he quoted people who other people, not him, had interviewed. Messages: K. Sawyer -- "Decades of research have consistently shown that brainstorming groups [who were told not to criticize anything proposed] think of far fewer ideas than the same number of people who work alone and later pool their ideas." Research by Nemeth -- Groups told that "most studies suggest that you should debate and even criticize each other's ideas" produced more ideas together and then subsequently on their own. Research by Uzzi -- (Lehrer's words) "The best Broadway shows were produced by networks with an intermediate level of social intimacy." Lehrer's take-home message -- "The fatal misconception behind brainstorming is that there is a particular script we should all follow in group interactions. The lesson of Building 20 is that when the composition of the group is right-enough people with different perspectives running into one another in unpredictable ways-the group dynamic will take care of itself. All these errant discussions add up."

"For Musk, going to Mars is way more than just cool. "Are we on a path to becoming a multiplanet species or not?" he has asked. "If we're not, well, that's not a very bright future. We'll simply be hanging out on Earth until some eventual calamity claims us." Impey makes much the same point. "Humankind evolved over millions of years," he observes. "But over the last 60 years, atomic weaponry created the potential to extinguish ourselves. Sooner or later we must expand beyond this blue and green ball, or go extinct." So does Petranek. "There are real threats to the continuation of the human race on Earth, including our failure to save the home planet from ecological destruction and the possibility of nuclear war," he writes. "The first humans who emigrate to Mars are our best hope for the survival of our species.""

"The chief justice's masterful opinion showed that line of argument for the simplistic and agenda-driven construct that it was. Parsing the 1,000-plus-page statute in a succinct 21-page opinion, he deftly wove in quotations from recent Supreme Court opinions. Who said that we "must do our best, bearing in mind the fundamental canon of statutory construction that the words of a statute must be read in their context and with a view to their place in the overall statutory scheme"? Why, it was Justice Scalia (actually quoting an earlier opinion by Justice Sandra Day O'Connor) in a decision just a year ago. And who said that "a provision that may seem ambiguous in isolation is often clarified by the remainder of the statutory scheme" because "only one of the permissible meanings produces a substantive effect that is compatible with the rest of the law"? Why, Justice Scalia again."
