Bruce is fantastic at conflict resolution: he always cuts to the core of an issue.

He isn’t battling his daddy issues or going on a self-righteous ego trip everytime there is an argument amongst the team. He focuses on the issue at hand. He goes straight to the heart of the matter
in each case — 

it is strange that SHIELD claims to be in the energy business
—

they are locating the Tesseract, but they demand to know why SHIELD is making weapons of mass destruction using it
—

that being scientists, they would have better idea as to what they are doing in regards to Vision
—

that they’re under a huge time constraint and the priority should be finding the infinity stones before deciding what to do with them. Thus, Bruce is
easily

able to clarify either the importance or the urgency of an issue; and highlights what needs to be the priority of the team.

This is also the reason why, in Infinity War, Bruce almost ended years-long feud between the Avengers by saying a simple line
—

“It doesn’t matter who’s talking to whom. Thanos is coming.”

aka there is a reason why Bruce had to be taken out of the narrative for Civil War to be possible.
