Not Fitting the Profile
Have a picture in your mind's eye of what an event or a leader should resemble and that may be less of a guide and more of a trap.
I recently noticed the bias in a meeting. A person's name was mentioned as a possible candidate for a position and it was rapidly ignored. There was no serious consideration of the person's abilities or perspectives; instead split-second analysis and then zap.
A profile was not matched.
That battle will be fought another day.
