[求助]高频argue 求解

An argument from the head of HR dept. in an automobile company:    

Study shows that employees of not-for-profit organizations, compared to those of for-profit organizations, are more likely to perform well when their performance is not monitored and evaluated. Interviews with employees of not-for-profit organizations also show that they have more motivation. They believe that their work is important to improve the society. They have personal reasons to perform well, even without financial returns. Therefore, our corporation should donate a significant portion of the overall profit to humanity, to increase the motivation and productivity of the employees, and thus to increase the profit. 

 只看出来increase the profit有错，还有interview 的validity， 还差一处，请高手指点。

可能参加non-profit organization的人本来就是比较有责任心的，而不是NPO让他们更有责任心

也可以认为，参与这次调查研究的not-for-profit的人在他们的老板的force下才做出这样的回答，而事实并非如此。可能事实上他们的motivation 是一样的或者for-profit的人更高。
