I would think that critical thinking is part of most people's every day lives. When I was deciding which college to attend, I had to consider the pros and cons of each school to which I was accepted. From critically comparing and analyzing what I wanted with what each school offered (including, but not limited to, cost, offers of scholarships and aide, distance from home, programs of interest to me, restrictions on freshmen, sports, etc.) and came to a final decision.
The same is true for the process I went through to choose where I would teach overseas. I found that the majority of schools offering excellent pay were in Asia and the Middle East. I knew I didn't want to be in a burka or forced to follow the restrictive cultural environment for women in the Middle East, so that left Asia. There are lots of countries in Asia, so again, I went through a process of elimination and comparison to finally decide on South Korea. Then, again, I had to apply to the schools with openings and from there go through the whole process again with the schools who offered me the position.
On a smaller, but not less important scale, as a teacher, I often have more than one section of the same class (honors seniors or traditional sophomores, for instance). If something didn't work well in the first class of the day, I had to access the weakness or what didn't work and change it before the next class came in...you think on your feet, tweak the lesson plan, and make note of the change for the next class/year.
I'm sure it's not that different for bankers and the decisions they make daily-- businessmen, translators, police officers, etc.
