It's funny that the paper author goes only into multitasking / concentration after wondering why people struggle to think critically. Sure, distracted thinking is generally not good thinking, but slowing down in and of itself won't improve your judgment skills. It's kind of a bummer that after the author says "there's a problem with critical thinking!" -- he moves on and doesn't talk about ways to actually develop critical thinking besides, you know, this 4 minute essay that just says "slow down the decision making process." I would have hoped he would have talked about different ways to analyze or prioritize problems, or discussed game theory or maybe gone into wicked problems[1].
Oh well
