I am taking a systems engineering class this summer. According to International Council on Systems Engineering (INCOSE), "Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems".
What does systems engineering have anything to do with egolessness? Actually nothing ! But, more recently, the field has been expanding beyond technological systems to include new discipline like social science. One of the readings assigned in this class was an HBR article by Chris Argyris, "Teaching smart people how to learn". Chris argues that the smart people fall into the trap of single loop learning. They know how to execute well what they know and they mostly succeed. But they don't respond so well (a.k.a respond defensively and blame others) if they fail. He further argues that these people could benefit from double loop learning (i.e. to reflect on one's failure to find the real causes of failures and find ways to address them).
What happens next is a comment by the course instructor. He shares an observation that this situation - smart people falling into the trap of single loop learning - is mostly present in a western way of life. The emphasis on "I" or ego puts a lot of pressure to rationalize and defend one's actions at the cost of letting it go and learn. According to him, the eastern world (he was primarily referring to Buddhist philosophy) gets around this problem by de-emphasizing ego. Not to mention, I had an interesting conversation with him after the class.
