Unfortunately, Dodril should not have corrected the Wonderlic scores because they were low compared to the WAIS. The WAIS was normed circa 1953 and the Wonderlic norms were from 1973, so people taking both tests in 1981 would be expected to score higher on the former than the latter, but no one knew about the Flynn effect in those days so it’s understandable.
However I found a paper by Arthur Jensen stating that in a nationally representative sample taking form IV of the Wonderlic Personnel Test (circa 1972?) whites had a mean of 23.32 with a standard deviation of 7.5. So using white norms (which were also used by the original WAIS):
IQ = [(wonderlic score – 23.32)/7.5] + 100
