Don't be afraid to be wrong
I agree on the parts about being more willing to share ideas and healthily accept criticism about them, but in general this article feels like it's presenting a false dichotomy: that you must either state things metter-of-fact or stay silent.It's possible to share a belief while expressing an appropriate level of uncertainty about it, and this is something I really wish more people did rather than blurting out falsehoods with confidence all the time. There's no harm in adding "I think ... is likely" or "AFAIK ... seems the most probable" etc. Reserve direct assertions for things you are actually sure about. And then if you're wrong about those things, reflect on what led you to be more certain than you should have been and try to prevent it from happening again.I think everyone should strive to never be 100% certain about things that end up being wrong.
