I agree, many of the available estimates are misleading, either because they do not break down salaries by starting and assistant prof, because they combine a number of disciplines or across all departments, or because they have a biased sample of respondents to the salary survey. For instance, APA estimates by region seem quite inflated from those listed on professional websites. This is probably because those that respond to the APA survey tend to be more prestigious or higher paying (also more likely to come from an urban area where cost of living is higher).
In my experience, and that of most people I went to graduate school who are still in academia, starting salary for psychologists range from $42,000 to $60,000. Most of these salaries were for less prestigious or at least less research heavy places. To break it down further for you:
-$42,000-$44,000 starting salary for 3 friends and 3 acquaintances, most at regional university focusing primarily on undergraduate teaching, but 2 started at liberal arts colleges focusing exclusively on teaching.
-$48,000 starting salary for a friend who teaches in a related department outside of psych. This is at a Rural State University
-$49,000-$51,000 starting salary for 2 friends at a regional university with a master's program (due to wage freezes, one friend still makes the same after 4 years on the job!; the other has recently left academia)
-$50,000 starting for a friend that works at a satellite school for a major Midwestern university.
-$53,000 starting for a friend at a reputable liberal arts college with some emphasis on research (this was just before the recession hit, and her salary increased for cost of living only once in the 5 years she has been there, though tenure will help boost it next year). This was also in a moderately expensive but quite nice city.
-$58,000 starting for 3 friends; one at a private university with PhD program in a large city, and one at a second tier state university with a PhD graduate program, and one at a Rural State University with a Master's Program
-$60,000 starting salary offer at a Rural state university with a PhD program and heavy research activity. The position did not actually materialize, so it went unfilled while the department tried to rethink what it wanted.
So it seems like the less paying jobs are far more frequent.
