Your post would have been far easier to read if you had stated that the mean IQ of the forum would increase if Joey were to leave. You caused confusion by stating that the IQ would increase by one standard deviation, thereby implying that the standard deviation would alter. This was not just my reading of the way this sounds but also of my daughter who is studying this at Uni. It is also obvious from the other postings on this subject that others have read this as a suggestion that the SD would increase.
Your assumption of an SD of 15 was based on Wechsler and as you have since pointed out other such experts have come up with varying different amounts for the SD in IQ assessments. You also implied in one of your posts that Stanford-Binet used the same formula but have since corrected this in the above post when you state that Binet assumes an SD of 16.
According to Wechsler the mean IQ would not change regardless of the presence of Joey or not as explained in my earlier post. Wechsler assumes a mean IQ as 100 regardless of the number of people tested. Therefore removing one from the test cannot impact on the mean IQ since the number tested has never been specified.

Your comment about a masters degree not taking 3 years to complete may be true in the US however in the UK a masters degree is for 3 years as standard and a PHD is for 5. It is likely that the length of time to complete a degree can vary form country to country. It is possible in the UK to take 5 years to complete an undergraduate degree if you are doing it as a part time student and in the UK once you have passed your undergraduate degree you are entitled to lecture at university so long as you achieved exceptionally high scores in your degree such as a first class degree with honours.
