My favorite piece of media is Contact (book and movie).

Ellie is someone I would consider having an open mind. She dedicates her work, at great risk to her own career, finding signs of extraterrestrial life. Despite everyone telling her not to waste time and resources on it. But she does and she does it by collecting the evidence first, and when she got it, double and triple checked it before making the announcement.

Avi kind of does the opposite. He hypes his ideas up first, often taking credit for others' work, without sufficient evidence.
