Some of the worst managers I've met are non-tech and trusting. A red flag is someone who says "my team can do whatever you ask them to do," before consulting the team.
Sometimes I still think about this.
Doc Ock: If we fire again this week, we could rupture the space-time continuum.
Kingpin: You got 24 hours.
I'm not sure if naivety is the best word. It's more like laziness that translates into blind trust. The manager doesn't manage, they just push the problem to someone else.
