Heisenberg's Uncertainty principle applies to the world of physics, the jist of it being that any measurement taken of a physical quantity affects its absolute value (basically the act of measuring something will affect your reading, e.g. using a ruler to measure length will affect the length. You can ignore this effect if you're measuring stuff in micrometres, but it becomes significant when you measure tiny stuff like atoms). I think we can extrapolate this idea to sociological studies. Making subjects aware that they are part of a study could possibly prejudice the results. Very few people consent to be part of a study for the 'greater good of science', but have some sort of vested interest, or lack thereof. Some are being paid and so may want to give the 'right' answers instead of being objective, in the hope that they 'please' the hands that feed them. On the other hand, some people are 'forced' to become lab rats. They may be a part of an organization say, a students at a university, who are required to fill feedback forms at the end of lectures, rating lecturers. Being forced to fill these at the end of every lecture, they naturally get tired of doing so and stop. Or even if they do, it's just a formality and they put in random numbers. Whichever white-collar yuppy is analyzing them will see that lots of people are rating professor X 5/5 and will falsely think that he/she is a great lecturer, whereas in reality, most of the kids are filling the numbers randomly. Hence, the data gathered is not truly representative. So what will happen is that if the lecturer is brilliant or crap, people will fill forms. If so-so, forms are returned empty. Which means that in the subsequent analysis, the faculty will see that the university has teachers at opposite ends of the spectrum, whereas MOST of the teachers are inbetweeners (or what statisticians like to call a normal distribution).
So what do we do about this? Beats me. I'm too lazy to think of ideas. Besides I'll falsely pass this off as trying to engage my readers. Your thoughts?
Come to think of it, I'm sure there's a sociological term for the content of this post. Again, I'm pulling the lazy card.
