When you invite others to reflect on a past decision with you - share all of the details. Even the details you left out of your thinking, share them. If ever you had a doubt, share the doubts you had. Especially if you're creating a decision-making tribe, the tribe owns the data - share it all.
I encourage you to be transparent because the devil is in the details! The information we choose to accept because it confirms our bias, or ignore because it challenges our bias, drives a large part of our decision-making process. As a result, that information must be on the table for discussion when employing others to reflect with you.
You're going to find this to be a challenge. I do - every day! It requires vulnerability.
Do you like to be wrong? No.
Do you enjoy it when people illustrate how you missed something? Hardly ever, I'm sure.
How do you see yourself when someone exposes your bias? Unsure, upset, unwilling to accept - all of the above?
If you want to be a better decision-maker, share all of the data with your tribe. Let them press for more, and be willing to put all your cards on the table. Only then, after sharing it all, will you start to see growth within yourself.
Share it all.
