In my experience in IT field there are generally two types of people, one who are open to new experiences and learning and other ones are the people who are skeptical about almost everything, these are “know it all” guys.
In the book “How Google Works” the author Eric Schmidt described these people as Hippos, they destroy the people in front of them with their experience rather than merit and it is really difficult to convince them for any idea.
These Hippos are everywhere in hierarchy model of a corporate, and this is the reason why there are revolutionary things happening in startups rather than in big corporate offices.
Being reasonable and being skeptical are two different things, people who are skeptical stick to their point of view not matter what, and people who are reasonable would might change their perspective after the discussion.
We should always be open to new learning and possibilities, because learning can come from anywhere irrespective of experience and hierarchy. I have learnt so many things from my juniors and it has truly changed my life.
