no matter how many people you test, you will not find a negative IQ score
If race times are normally distributed around 28 minutes with a standard deviation of something or other, or bowling scores were normally distributed around 180, you wouldn't conclude that if you had enough people someone could theoretically get a negative race time, or a bowling score of -10 or 310.
edit: I see now- you're right :) The formula I was thinking of is the very old one, which is like (individual score/avg. score* 100). When SD is part of the formula rather than just an assumption about the data you can totally get a negative score.
