Researchers find IQ scores dropping since the 1970s

You might be right. I've taken an IQ test at the beginning and at the end of my highschool and my scores dropped from 136 to 132 in four years (Wechsler scale if I recall correctly), which can be attributed both to organized education and increasing reliance on technology. Moreover, as the average 100 IQ has gone down in absolute terms, the change is even more drastic in my case :P

However, and despite me being prone to tell this as a funny anecdote, this might be a case of sample bias or other statistical imprecision.

4 points on a score that high just sounds like noise.

Iirc WAIS (and most IQ tests) will only compare to your age group, so your drop in IQ is not relative to the general population.

Edit,and as the other person says, the reliability more than 2 standard deviations up is somewhat limited, so a person scoring within 4 points is reasonable.
