I'm not very close to the core of EA, so maybe my perspective is not the most accurate, but one thing that I feel sets EA apart from other movements is that EA people generally are happy to disagree and change their mind based on good ideas/arguments/evidence from anyone inside our outside EA. For example:
Well, right today there's an article on the economist, one on the guardian, two things on the front page of hacker news, etc. This is a debate, with clear criticism of their current views. Let's see.

I expect and hope that people within EA will keep learning from mistakes and changing their views.
