Leveraging the skills and abilities of others in conjunction with your own can be frustrating.  Independence and belief in our own abilities and self-worth lead us to challenge the value of collaboration.

That is to say, while the quality and effectiveness of our achievements are greatly enhanced by acting en mass rather than independently it is not human nature to do so.

Interacting with Others

Going it alone can be very satisfying.  Individual accomplishments make us feel good.  Group accomplishments are still worth applauding and can be very satisfying but we are just a cog in the wheel.

A very challenging aspect of working with others is the need to attain a consensus.  This is a general agreement among all parties.  Making a unilateral decision and forcing it on others is so much easier.

Therein Lies the Rub

Leaders with granted power can abuse this privilege by taking the easy route.  That is rather than attaining consensus, which means the best ideas and knowledge all participants gets leveraged, they just override and push forward with their decision.

The disadvantage of this approach is simply that is has a lower likelihood of arriving at the best approach.  Intuitively the larger the information base, the combining of multiple processing power and the diversity of thought will provide better results than a single stream,

Albeit it slower, taking the extra time and effort to consult, discuss and achieve consensus will in most cases (outside of dire emergencies) produce the best results.

Granted power should not be used recklessly.
