Came here to say this. Being afraid to look stupid helps with keeping a certain image for employers. If you aren’t afraid to look stupid but end up failing a lot and don’t try to fake that confidence and knowledge after while you’re still working things out, you end up with the devil effect unfortunately.

Also, if you end up in a position above others, their trust in you often relies on how confident you act, even if you’re not sure of yourself.

So I guess the takeaway tends to be: don’t be afraid to fail so you can learn, but don’t be too obvious about that failure.
