naysayer

One naysayer pointed out that these athletes were simply reverting to the mean.(一位反对者指出，这些运动员只不过是从巅峰状态回复到了平均水平。)

I would rather deal with the naysayer who proclaims "lean doesn't work" than the dismissive "lean was good but we already moved on to xyz."(我更愿意与声称“精益没有用”的反对者打交道，而不是那些不屑一顾的认为“精益很好，但我们已经在做别的事了”的人。)

The Naysayer. This office dweller delights in shooting down ideas.(办公室里的这类人以扼杀想法获得乐趣。)

Be warned that the majority of people out there will go into naysayer mode automatically.(值得注意的是，大多数这类人都会自动的变为反对者。)

Give up being a naysayer.(拒绝做否定主义者。)

When you have such an event in prospect, the naysayer who argues that you are over-reacting is more likely to be right than wrong.(如果预计此类事件，则认为你反应过度的那些反对派更有可能是正确而不是错误的。)

Only on the newspaper can you say things like "I was born in the year of the horse, that is why I am a naysayer."(只有在报纸上你才能说类似于“我出生在马年，这就是为什么我爱唱反调。”)

Instead of being a critical naysayer, put your mental skills to work by analyzing the details and contributing a practical plan that helps to handle the unanswered questions.(用你的心智去分析细节、推行切实可行的计划、处理悬而未决的问题吧，别再唱反调、作怀疑论者了。)
