The writer Matt Richtel notices that his 4-year-old son likes to compete, and win, at everything - even toothbrushing - and wonders: is competition somehow bad or destructive? Do you think competition is healthy? In general, do you perform better in situations in which you're competing, or in situations in which you're collaborating? In "The Competing Views on Competition," Matt Richtel writes: Just before bedtime on a recent night, two toddlers marched reluctantly to the bathroom to brush their teeth. Students: Do you perform better in situations with competition or collaboration, or both? Does competition raise or lower your performance level? Does it depend on the situation? What about collaboration? Is competition or collaboration more likely to get you to work harder or keep you more engaged with a problem or project? Is competition or collaboration more likely to make you anxious or damage your self-esteem? What advice would you give to Mr. Richtel?
