Give and take policy may not be the best alwaysWe hear many times that give and take policy is the best always. Give respect and take respect. When you want something from someone, you should be ready to give something to the other person. When we take so many resources from nature we should give something back to nature. It holds good in many places.
But recently I have seen a new concept. When people work for their PhD, they have to make a thesis and submit to the university and the university will send for adjudication to some professors from other universities. In this also they use the give and take policy. A professor will send his candidate's thesis to a professor whom he knows well and the other professor will send his candidate's thesis to this professor. Both of them approve the thesis they received. Some universities send the thesis to a foreign university also where this give and take policy will not work.
There may be many other areas also where this give and take policy will have some adverse effects. I solicit the opinions of learned members on this.
