At my previous job I had this problem. It was intensified by, what I perceived to be, conversation that was more flawed than accurate. I heard so many statements I couldn't agree with, I didn't know where to start commenting on anything. In other worlds, the whole idea or conversation that was being discussed was wrong. Very often I had nothing to say, because how do you tell a team of co-workers that everything they're saying is wrong?

Of course, many would assume I was more likely to be wrong, disagreeing with so many people. I worked in a very stale industry however, no where near as pioneering or cutting edge as some dream jobs in the valley: some would say legacy, enterprise software. So I beg to differ the opposite is possible also. Also, I worked there for years, knowing most colleagues would do anything just to coast, I had far more than 5 minutes to give the processes consideration.

Regardless, what I learned is, if everything in the conversation sounds wrong, and the appropriate "5 minutes" have been given, perhaps you are participating in bad conversations / keeping bad company. Switching jobs is the best thing that could have happened to me in order to improve my expertise.
