In general, do professors work at liberal arts colleges because they do not want to have to face the pressure of writing a lot of research papers? Instead they want their evaluations to be skewed towards their teaching quality?
You're not expressing the question in the most flattering way, but yes: most academic jobs are a mix of research and teaching (and also service / administration), and there is a lot of variation in the importance placed on each from job to job. Some people are more interested in one than the other, and the faculty at liberal arts colleges have signed up for a job in which more emphasis is placed on teaching and student contact than a, well, a research university.
At a good liberal arts college faculty are still expected to be research active -- it's just that they spend more hours per week on teaching than their colleagues at a more research-oriented institution. Someone who felt like writing research papers was pressure that they didn't want to face would probably be more comfortable at something like a four-year, junior, or community college, in which in most cases the research expectations are really nominal.
