A "thinking job" usually doesn't mean commenting on this or that without knowing what they're talking about (well, there are people who do that but those are in the top 0.1% of the population). Most "thinking jobs" require you to conduct tedious research, getting engaged in discussions, being flamed in front of an audience etc. And most "thinking jobs" limit your expertise to one tiny bit of reality which means that you spend the rest of your life with thinking about inane details hardly anybody really cares about. (Again there are exceptions because once you get famous you can easily pass as expert for everything.)
