> I once worked with a guy who had strong opinions during code review and changed them often (usually after reading blog). I hated working with him.

> With people who have strong opinions and stick to them you can at least learn their opinions and adapt or fight once. If they change every week, you have to fight or adapt constantly. Last week you need to use x syntax wherever possible, this week you must not use it. And big deal about difference each time.

If they are constantly changing their opinions back and forth based on whatever blog they read most recently, those aren't strong opinions weakly held. They're just weak opinions, strongly advocated (or strongly enforced, depending on your co-worker's authority).

Also, if they are privileging opinionated blog posts over the arguments of their colleagues, the solution is simple: start a blog.

Another reason for people trying too look overly confident is when they are overly exposed over a certain topic.

For example, if you have very narrow job titles and roles in a team ("he is our DevOps, she is our architect"...) everyone will have to defend their role, often trying to sound infallible.

If instead you make the whole team responsible for all team tasks, everyone will be more open to leveraging everyone else's suggestions.
