Never assumed I was the 'master', but I do know how the test is scored.
Why can't you use researched facts to disprove what I said instead of just saying I'm wrong with no supporting arguement besides what your so called psychologist said? If you did the slightest bit of research, you would see the test is scored on be strict bell curve. If you've ever taken a college course thats on a curve you should be familiar with them. A set number of people achieve each grade. This is just like the WAIS IQ test is scored for each age group. If every person in the population who is 21 takes the test right now, a SET number of people will achieve each score because its all in relation to eachother. Now lets fast forward 40 years when all the 21 year olds are now 61 year olds. Again, they all take the test. The same number of induviduals will achieve each score, thats the nature of the bell curve. This directly disproves your comment that as we age, our scores tend to move towards 100.
I would love to hear you counter these facts with facts of your own, but until then, please don't assume I don't know what I'm talking about.
