How honest are you? If you're speaking to an individual, perhaps you would consider being candid. In a group do you wait to see what others might bring forward or speak the same as if it were one-on-one?
It's not most of our natural tendencies to strive for candour. We've been brought up in a world that encourages us to be nice, be polite and not stir the pot. I know I've thought many times "well I'm sure this question has occured to someone else, so I'm sure if it's important someone else will ask it."
Turns out that while the question has occured to someone else, they are thinking those same thoughts as you, which means no one is asking the question. There's also a good chance that because we all see the world a little differently, that you do have a unique insight to share.
Medium suggested this article for me related to this. It's about Pixar's company culture that encourages this openness to thrive.
A hallmark of a healthy creative culture is that its people feel free to share ideas, opinions, and criticism. Lack of honesty, if unchecked, leads to dysfunctional environments. — Ed Catmull, President, Pixar
Pixar has something called their Braintrust meetings. Every few months there's a meeting in which people discuss in an open talk the progress of their movies. There's no authority and everyone is equal in the meeting. There is an obligation and expectation for honesty and good conversation. That lack of authority means it is also up to the project lead about what feedback to take or leave moving on from the meeting. The article also shares an example of a Braintrust that happened.
We can all create our own version of Braintrust. If we're ready to recieve honest feedback and figure out how to filter through this, we can certainly make any idea even better.
